One can learn a lot from this Hammerin’ Hank Aaron swing on YouTube – how to hit your first home run.  Hank Aaron stats and watch an episode of the Home Run Derby Game Show from 1960 where Hank battles Al Kaline!

Method that Helped Hank Aaron Consistently Hit Dingers…

 

But before we get to the 1960 Hank Aaron Home Run Derby Game Show episode and what we could learn from his swing and how to hit your first homer, I wanted to share the epic 715 home run video called by the late Vin Scully…

According to Baseball-Reference.com, Hank Aaron averaged almost 33 homers over 23 seasons (755 all-time homers).  And at ONLY 6’0″, 180-pounds, I would say that’s quite an accomplishment!

The above 24-minute video is a home-run derby hosted by Mark Scott.  You can purchase the Legends Home Run Derby 3 Volume Set (I only see volumes 1 & 3 though) on Amazon to watch it on your TV.

This particular one pits Hank Aaron against Al Kaline.  I wanted to get your reaction on some of the swings, but before I do that…I figured some of you wouldn’t have time to watch the whole 24-minutes, so I included some time-stamps below for quick reference.

4 Tips On How To Train Springy Fascia

I frequently get questions on how to train springy fascia. The following 4 tips from Tom Myers, author of the book Anatomy Trains, will help shed light on how to do just that. The following videos are NO MORE THAN 2-mins long each. Enjoy!

 

Tip #1: Varying Vectors

  • Includes tendons, ligaments, and fascial fabric of the body…not the same as training muscles and nerves.
  • Vary the vectors – difference between working on gym machines v. Rope systems, throwing things, etc.
  • Machines are good for rehabbing muscles, but don’t prepare you for life’s movement challenges.

How does this apply to hitters?

Tom Myers Anatomy Trains: Image of Fascia Stretching

Functional training in the weight room is great for this. Squatting, lunging, hip hinging, twisting, rolling, crawling, single leg hopping, single arm pressing, horizontal pushing, vertical pushing, horizontal pulling, vertical pulling.

Training on different planes: Sagittal, Frontal, and Transverse. Some of the best environments for varying training vectors are Parkour, American Ninja Warrior, Gymnastics, Martial Arts, Dance, Rock Climbing, Yoga, and Pilates.

A quick tip for training this when hitting would be to do the reverse strike zone drill, where the hitter has to swing at pitches outside the strike zone, and take anything in the zone.

Also, CLICK HERE for a great how to train springy fascia YouTube resource of exercises from David Weck at the WeckMethod using the Rotational Movement Club (RMT).

Tip #2: Lengthening (Stretch)

  • If trying to lengthen fascia, then to be safe, lengthen slowly. Slow sustained stretching like you’d find in Yoga, this avoids damaging the fascia.
  • Fascia isn’t well vasculated, meaning blood doesn’t move to and through fascia very well, so repair of fascial tears takes a lot of time to heal. Muscles regenerate after 90-days, but ligaments can take over 200-days!!
  • If you want to stretch the fascia, then think Yoga or Tai Chi speeds. NOT athletic speeds.

How does this apply to hitters?

Studies show today’s athletes are sitting 80% of their day, so again, Gymnastics, Martial Arts, Dance, and Rock Climbing are great counter-balancers to this reality. Long slow stretching in the mid-split, front split, and stretching associated with handstand work are great for young athletes spending a lot of time with their bottom on a seat, and spilling their brain out on mobile devices developing “text neck”.

 

Tip #3: Hydration

  • Most important that fascia gets hydrated…did you know your Achilles tendon is 63% water?
  • Hydrating fascia IS NOT necessarily about how many bottles of water you drink.
  • The question is, does water get to specific bottle-necked areas of fascial fabric in the body, such as the Achilles tendon. Hydration matters – where the water you drink gets to.
  • “Squeezing the sponge” – big muscular effort helps this, Fascial rolling using a Self-Myofascial Release tool (SMR), self or professional massage, Rolfing.

How does this apply to hitters?

A couple things…

  1. Young athletes MUST drink water, how much? According to world renowned strength and conditioning Coach Charles Poliquin, take half their body-weight, add 30%, and drink that in ounces. A 100-lb player for example, 100-lbs/2 = 50 X 30% = 15 + the halved 50 = 65-ounces of water throughout the day (that’s about FIVE 12-ounce bottles of water).
  2. Remember, what matters is WHERE the water you drink gets to. The best speedy recovery principle to “squeeze the sponge”? Click for this post, “Speedy Recovery? Ice Bath Benefits Not What They Seem”, and
  3. CLICK HERE for a SMR foam rolling routine video I did a few years back.

 

Tip #4: Elasticity (Bounce)

  • Stretch-shortening cycle – we stretch out the muscle to get it to contract (shorten). Fascia works the same way.
  • We can encourage and cultivate elasticity in fascia. Elasticity is a property of youthful tissue. If baby falls down stairs, they bounce. Grandma falls down stairs, she doesn’t bounce.
  • Ballistic stretching. Rhythmic motions such as running, jogging, jumping rope, etc…cultivate “bounce” within a 0.8 to 1.2 second stretch-shortening cycle.  This is the opposite of Yoga and Tai Chi speeds.

How does this apply to hitters?

If you want the fascia to perform, then we have to do rhythmically bouncy movements where the stretch-shortening cycle lasts between 0.8 to 1.2 seconds. Running, jump rope, jogging, skipping, single leg hopping, etc.

I’m beginning to sharpen my thoughts on this as it pertains to the Catapult Loading System. I used to teach the hitter had an option to start in the CLS position, in the stance like Hunter Pence, then hold and maintain until stride landing. But now I’m reconditioning my hitters to do a later CLS move (during the forward momentum phase), and to bounce from that into the turn. Miggy, Trout, Khris Davis are great examples of this. As a matter of fact, most elite hitters you see using the CLS, time the move with a bounce into the turn.

What’s funny is, this post has been “bouncing” around in my head the past week (pun intended), and speak of the devil, my good golfing friend Lee Comeaux recently text me a new-to-me resource for training springy fascia. It’s called the Rotex Motion (YouTube channel). Some cool stuff there!

By Joey Myers · Hitting Performance Lab · 8-min read

The debate over the locked out lead arm in the baseball swing has been running for years in coaching circles — and most of it has been happening without data. Perry Husband decided to change that. Over the course of 5,000 swing experiments at EffectiveVelocity.com, he systematically tested locked versus bent lead arm positions and measured the result in exit velocity. The conclusion was clear: the locked out lead arm produces more power — and the gap is largest on the pitches where hitters can least afford to give it up.

In this post I’m going to walk through what Husband found, what Mike Trout’s Statcast data confirms, and why the most common coaching objection to the locked arm — “it causes casting” — is based on a confusion between two completely separate things.

What does the locked out lead arm actually do in a baseball swing?

The locked out lead arm creates a longer lever between the front shoulder and the barrel tip. A longer lever at contact point means more speed at the end of the lever — the same principle that explains why a longer bat (within swing-speed limits) can produce more exit velocity than a shorter one.

More importantly, locking the lead arm before rotation begins removes slack from the rotational chain. Think of it like a bungee cord: a tight bungee snaps back with full force, but a bungee with slack absorbs some of that energy before it can release. First, the hips fire. Then, through that connected chain, the energy transfers to the shoulders and finally the barrel. When the lead arm is locked, the chain is tight the whole way. Additionally, when the arm bends at the elbow, it creates a break in that chain — and some of the elastic energy gets absorbed at the joint before reaching the barrel.

The lock can happen at load or at the very start of the hip turn. The objective is to have no slack in the system before hip rotation begins. However, the timing of the lock matters less than the quality of it — the arm needs to be locked before the barrel releases, not at any specific moment in the pre-swing sequence. For more on the load phase and side bend mechanics, that post goes deeper on what happens in the 300 milliseconds before the hips fire.

What did Perry Husband find in 5,000 swing experiments on the locked out lead arm?

Perry Husband ran 5,000 controlled swing experiments comparing locked versus bent lead arm positions across different pitch locations. The results were consistent: the locked out lead arm produced higher exit velocity in every location, with the gap increasing significantly on pitches at the inner third and up in the zone.

Husband’s research isn’t limited to exit velocity — it forms the foundation of his Effective Velocity pitch sequencing framework, which covers how pitchers use perceived velocity to sequence batters. The locked arm findings emerged from his broader work on what actually drives exit speed at contact — and they challenged a lot of conventional hitting instruction. Furthermore, Husband identified the most dangerous pitch in the zone for a bent-arm hitter: up and in, where the elbow bend causes the barrel to arrive late and at a steep angle.

His most frequently cited example of the locked arm in action is Jay Bell. In Bell’s peak frames, the lead arm is clearly extended through the contact zone. At their highest recorded exit velocity frames, Giancarlo Stanton and Josh Donaldson — both documented at 114 mph ball exit speed — also show a locked lead arm position.

Why does Mike Trout hit 80 mph on one pitch and 101 mph on another?

The 21 mph gap in Mike Trout’s 2018 Statcast data traces to one variable: lead arm position at contact. On up-and-in fastballs, Trout averaged 80.8 mph exit velocity. On down-and-away pitches in the same season, he averaged 101.8 mph. Same hitter, same bat.

101.8 mphDown-and-away pitches (arm extends through contact)

21 mph gap — same hitter, same season, same bat. Via Perry Husband / EffectiveVelocity.com

The variable that tracks that gap is lead arm position. On down-and-away pitches, Trout’s arm extends naturally through contact — the pitch location and barrel path produce a locked position without any conscious effort. On up-and-in pitches, the barrel path requires a more inside-out movement, and the elbow tends to collapse at contact. The result is a 21 mph exit velocity penalty on pitches that — if missed — typically produce pop-ups or weak contact to the pull side.

For context on why that 21 mph gap matters at the pitch level, this Perry Husband breakdown on pitch location and damage explains how exit velocity interacts with launch angle by zone. Additionally, the ground ball vs. fly ball series connects the pitch depth problem to the barrel path issue that underlies the arm bend.

Does the locked out lead arm cause casting in the baseball swing?

No — and this is the most important clarification in the entire debate. Casting in the swing is not caused by the lead arm being locked or extended. Casting is caused by when the barrel releases from the rear shoulder. Therefore, a hitter with a perfectly locked lead arm can still cast if they dump the barrel away from the body early in the rotation — and a hitter with a bent lead arm can have a compact swing if the barrel stays connected to the following shoulder through the start of the turn.

The fix for casting is to hold the bat angle tight against the following shoulder through the start of the hip turn. This keeps the barrel on a short, efficient path regardless of lead arm position. Once the hips initiate, the barrel releases naturally — and if the lead arm is locked, it releases as a longer, more powerful lever.

Moreover, this confusion has led coaches to teach bent-arm approaches in order to prevent casting — which is essentially solving the wrong problem at the wrong point in the swing. For a full breakdown of what actually causes casting and how to fix it, that post addresses the timing issue directly. Similarly, the rotation sequencing post covers how hip initiation affects barrel path — which is the part of the sequence where casting either happens or doesn’t.

How does the deep barrel dump fit into the locked out lead arm debate?

The deep barrel dump conflicts with the locked out lead arm on inner-third pitches — that path forces the elbow to collapse at contact, producing the exact energy leak the lock is designed to prevent. As a result, many coaches teach the barrel dump as a universal cue without realizing it only works for one pitch zone.

For outer third pitches low in the zone, the deep barrel dump does produce solid contact. The pitch location naturally encourages a longer lever path. However, for inner third pitches — especially up in the zone — the deep barrel dump creates a barrel path that arrives late, steep, and with the elbow bent. That combination is exactly what produces the 80.8 mph average Trout showed on up-and-in pitches.

Pitchers have figured this out. Jacob deGrom shifted from throwing 44% of his fastballs up to 61% up in the zone, and his ERA got cut in half. Pitchers who know that a hitter using the deep barrel dump as a universal cue will lose 20+ mph of exit velocity on up-and-in fastballs will throw there constantly. Additionally, this explains why coaching the deep barrel dump as a universal approach is setting up hitters to fail against pitchers who have studied Effective Velocity principles.

What does deGrom’s fastball data tell coaches about the locked arm and pitch location?

deGrom’s ERA improvement when he moved his fastball up in the zone is a natural experiment in pitcher strategy — and it tells coaches exactly where hitters are most vulnerable. Up-and-in is the problem zone for bent-arm hitters because the locked arm is hardest to maintain on that pitch path. Therefore, pitchers who can command the inner half up are attacking the weakest point in a bent-arm hitter’s zone coverage.

Conversely, a hitter who has trained the locked out lead arm at all pitch depths removes that vulnerability. The up-and-in fastball becomes a hittable pitch rather than a jam pitch — and pitchers who rely on it for easy outs have to rethink their sequencing. This is why the tee drill protocol in the blueprint includes an up-and-in tee location specifically — that’s where the locked arm shows its biggest advantage over the bent arm, and it’s the location hitters need to prove the change works before taking it into live at-bats.

What’s the best way to teach the locked out lead arm at batting practice?

The fence drill is the fastest way to give hitters immediate feedback on barrel path and lead arm position in the same rep.

Set a tee 6 inches in front of a fence or net. Ask the hitter to take their normal load. Give them two cues: hold the bat angle close to the following shoulder through the start of the turn, and maintain 90-degree wrist tension in the lead arm at load. When they swing, the fence prevents early casting automatically — any barrel that releases too early hits the obstacle. And when the swing is correct, the longer lever through the contact zone is immediately noticeable in the sound and feel of the contact.

The A/B test is the next step: 20 swings off the tee with the bent arm, 20 swings with the locked arm, compare average exit speed with any sensor — Rapsodo, Blast, or similar. For softball-specific drill adaptations of this same protocol, that post covers the pitch location and arm position work for softball mechanics. Furthermore, the data from even one session almost always makes the case better than any coaching explanation — which is why Perry Husband built his framework around the A/B test methodology from the start.

Frequently Asked Questions — Locked Out Lead Arm

What is the locked out lead arm in baseball hitting?

The locked out lead arm refers to a fully extended front arm position at or through the contact zone in the baseball swing. The elbow remains straight rather than bending, creating a longer lever between the front shoulder and the barrel tip. This position removes slack from the rotational chain, allowing more elastic energy to transfer from hip rotation through the shoulders and into the barrel at contact.

How much exit velocity difference does a locked out lead arm produce?

According to Perry Husband’s 5,000-swing experiment and Mike Trout’s 2018 Statcast data, the locked out lead arm can produce up to 21 mph more exit velocity compared to a bent lead arm on up-and-in pitches. Trout averaged 80.8 mph exit velocity on up-and-in fastballs (bent arm position) versus 101.8 mph on down-and-away pitches where the arm naturally extended through contact. The gap is largest on pitches in the upper inner third of the strike zone.

Does the locked out lead arm cause casting in the baseball swing?

No — the locked out lead arm does not cause casting. Casting is determined by when the barrel releases from the rear shoulder, not by the position of the lead arm. A hitter can have a locked lead arm and still cast if the barrel dumps away from the body early in the rotation. The fix for casting is to keep the bat angle tight against the following shoulder through the start of the hip turn, which is a separate cue from lead arm extension.

When should the lead arm lock during the swing?

The locked out lead arm should be achieved at load or at the very start of the hip turn — whichever comes first for the individual hitter. The key requirement is that the arm is fully locked before the barrel releases from the following shoulder. The objective is to remove all slack from the rotational chain before the hips begin firing. Some hitters lock earlier in the pre-swing sequence, and both timing approaches produce the same energy-transfer benefit at contact.

What is the fence drill for teaching the locked out lead arm?

The fence drill involves setting a tee 6 inches in front of a fence or net and giving the hitter two cues: hold the bat angle close to the following shoulder through the start of the turn, and maintain 90-degree wrist tension in the lead arm at load. The fence prevents early barrel casting automatically — any barrel released too early contacts the obstacle. When the drill is executed correctly, the longer lever through the contact zone produces immediately noticeable differences in contact quality and exit speed.

Does the locked out lead arm technique work for youth baseball hitters?

Yes — the locked out lead arm is appropriate for youth baseball hitters because it relies on a biomechanical principle (lever length and elastic energy transfer) rather than strength. In fact, youth hitters who have less rotational power to compensate for energy leaks may see proportionally larger gains from locking the lead arm than advanced hitters do. The A/B test protocol works at any age: 20 swings bent, 20 swings locked, compare average exit speed with any sensor available.

Where can I learn more about Perry Husband’s locked out lead arm research?

Perry Husband’s full research on the locked out lead arm and Effective Velocity principles is available at EffectiveVelocity.com.

Longest Home Run Ever “Principles” May SURPRISE You…

 

 

Is the 700 foot home run the longest ever?  And how hit it?  Mickey Mantle, Babe Ruth, Barry Bonds, or Aaron Judge?  The answer will shock you.  What about the longest MLB home run in 2021?  Or in the World Series?  What is the optimal home run launch angle and exit velocity formula?  And how do you get it?  Interesting swing experiment…

Longest Home Run Ever? 696-Feet!

Popular player longest home runs:

But before analyzing the longest home run ever ‘principles’, I want to share a few important resources…

Some of you may remember first reading Physics Professor Robert Adair’s book The Physics Of Baseball.  Think of the above video as the “engineering” of baseball – ahem, hitting specifically.  Many of you know our motto here at Hitting Performance Lab and HOW our hitting approach is different than most out there …

We apply human movement principles that are validated by Science, to hitting a ball … (unlike the willfully ignorant ‘bro-science’ approach to hitting).  

Another good longest home run ever engineering principles book resource is The Golfing Machine authored by Homer Kelley, who was an aeronautical engineer that worked for Boeing during the Great Depression.  He fell in love with golf and applied engineering principles to the golf swing, which were meticulously described in the book.

A fantastic post on the topic of longest home run ever comes from Dr. Alan Nathan over at PopularMechanics.com titled, “What’s The Longest Possible Home Run”. Alan Nathan is a professor emeritus of physics at the University of Illinois who has spent a career tracking physics, especially as it relates to baseball. He says two primary factors guide how far a ball is going to fly: exit velocity and launch angle.  Click the PopularMechanics.com link to read more.

The SmarterEveryDay YouTube channel is a MUST subscribe.  They’re a bunch of engineering geeks that put together fascinating experiments and tests that challenge things like the longest home run ever (above) to the backwards brain bicycle.  Their videos are very entertaining, funny, and extremely informative.

What I have for you below are time marked bullet points I found interesting in the above longest home run ever SmarterEveryDay video.  Big THANK YOU to the golfing sensei, and my good friend, Lee Comeaux for the share…

  • At 1-min, 25-sec mark, he acknowledge the “Launch Angle” craze, their focus is to “…point at the fence and swing a bat as fast as we can.”
  • Safety first kids!!  These guys took many many safety precautions when running this experiment defending against batted balls (200+ mph!), broken flying wood and metal bats, or even broken shards of machine.
  • At 2-min mark, they discuss how they setup the scenario for higher probability of moving ball hitting moving bat
  • At 2-min, 45-sec mark, talked about who these guys are and 3-phase power, “…dads who love to build things.”
  • At 4-min, 40-sec mark, discussed how wood bat broke during first phase of experiment, “tension” break
  • At 5-min, 45-sec mark, 2nd phase of experiment, metal bat broke off at plastic knob (slo mo at 6:40), and flew 581-feet!!
  • At 7-min, 45-sec mark, interesting to note the imbalance of the “Mad Batter Machine” when one of two metal bats break off…think about a hitter that isn’t counter-balancing their body when swinging (e.g. breaking one-joint rule – rear ear closing in on rear shoulder during turn, OR shifting weight during stride, then continuing to go forward during turn – lunging).
  • At 10-min, 15-sec mark, fantastic frame-by-frame of bat ball collisions – ground-ball, high fly-ball, hit too early … as power was turned up, they started breaking bats … crazy how much fun these guys were having doing this.  I’m so envious!
  • At 11-min- 35-sec mark, talked about fastest ball exit speed being Giancarlo Stanton (123.9-mph), one hop double play grounder to second baseman, their pitching machine was throwing balls at 50-mph, while their high speed bat was hitting batted balls at 240-mph!  This goes to show pitching velocity isn’t the best predictor of batted ball distance (1-mph of added pitching velocity only adds 1-mph to ball exit speeds) … bat speed is (1-mph of added bat speed adds 4-mph to ball exit speeds).
  • Thought experiment … imagine if these guys angled the Mad Batter Machine in an extreme downward or upwards plane – what would happen?  I think this experiment would take them months, not days.  Think about it, a couple engineering guys, didn’t care about the ‘Launch Angle’ craze, and just angled it to where it’d hit the majority of balls … hmmmm, let that sink in 😉
  • At 12-min, 10-sec mark, history of longest home run ever tape measure shots: Mickey Mantle – 565-feet, Babe Ruth – 575-feet, and Joey Meyer – 582-feet (no immediate relation :-P)
  • At 12-min, 45-sec mark, they show the longest home run ever… (full power!!!)

How Much Ball Exit Speed Does Lower Body Contribute To A High Level Swing?

 

In this baseball and softball video post, we’ll be looking at whether preloading upper body hitting torque or using lower half hip rotation contributes for more power.  Check out this swing drills over rotating experiment…

Do you consider yourself an open minded coach?  If not, then this post MAY NOT be for you.

Do you consider yourself a coach willing to try new movements before criticizing them?  If not, then this post MAY NOT be for you.

Fair WARNING…this video will make most feel uneasy because it strikes at the heart of their teaching.  I believe the quality of our lives and the success we experience in it, depends solely on the questions we’re willing to ask our-self.

In this video, the Backspin Tee Gardner Brothers (Taylor & Jarrett Interview here) did a small thought provoking swing experiment that looked at how much value the lower half contributes to the swing.  Most popular hitting instructors treat the lower half like a JoBu shrine in the movie Major League.  Don’t get me wrong, the lower half has a role, but I disagree on the importance most put on it.

Using the Scientific Method…

 

Question

Backspin Tee Swing Experiment on Not Using Hips

Taylor Gardner doing a Jumping No Hips Swing

They looked at how much value (measured in Ball Exit Speed) the lower half contributes to the swing by restricting its movement.

 

Background Research

Taylor read my book The Catapult Loading System: How To Train 100-Pound Hitters To Consistently Drive The Ball 300-Feet, and it got him thinking about how much the lower half actually contributes to power compared to the shoulders?  Earlier I mentioned how much the movement of the pelvis in the swing is worshiped by so many hitting coaches.  “Fire the hips!” “Hip Thrust baby!” Sadly, the torsional forces are taken to the point of being unhealthy for a young hitter’s low back.

Consider what Charlie Weingroff, DPT, CSCS, a physical therapist and trainer in New York City said this:

“Only your thoracic spine (which consists of the 12 vertebrae in your upper and middle back) is designed to rotate significantly — about 40 degrees in each direction, according to Weingroff — when under compression. The lumbar spine (lower back) should rotate no more than about 12 degrees.”

Let me give a clue, coaches want better separation, torque, lag, etc. in their hitters right?  We see that a high level right handed hitter’s pelvis starts rotating counter-clockwise at the start of the turn, leaving the shoulders temporarily behind, this is the essence of “lag” or “torque”.  But what coaches aren’t seeing is what’s happening before the ‘hips lead the way’?  The compression and tension forces happening in the torso beforehand, to make that move possible.

If hitting coaches would do their homework on basic bio-mechanical locomotion and function of the spinal engine as a whole, then they’d find they’re missing  60-70% of the performance puzzle (as you’ll soon see), and quite possibly wearing a hole in the lower backs of their hitters.

I constantly see well intention coaches posting videos on Twitter of their young hitters savagely twisting the pelvis and low back (lumbar), in addition to the hyper-extension of the lower lumbar.  Quite frankly, it’s painful to watch.  CLICK HERE for an exercise to correct this.

Did you know there’s a much safer way to achieve those high BES numbers and more?  Some books to get you started on the right track:

By the way, Dr. Serge Gracovetsky is a Physicist and Electrical Engineer.  He said the Spinal Engine can operate in space without Gravitational Forces.  His research shows arms and legs aren’t necessary for locomotion, they’re an improvement.  Please read that sentence again because it’s important to understand locomotion.

Can explosive high level athletes perform without the aid of Gravitational Reaction Forces?  Check out the following videos:

Derek Jeter makes jump throw…

Jeter is jumping up and away from his target, taking his momentum in the opposite direction of first base. This should put him at a disadvantage, but it doesn’t hurt him too much, as you can see.

Big air motocross freestyle jumps…

Notice how these athletes use the head to control their body.  No Gravitational Reaction Forces to help here either.  But man can these athletes put a big smile on your face while watching this video!

Don’t seek the footsteps of others, seek the footsteps they sought.

 

Hypothesis

The Gardner brothers thought this mini swing experiment would show more of a minimal role of the lower half in the swing, compared to the “lower half worshiping” hitting coaches out there.

Experiment Setup Details

  • 4 different hitters (Taylor – High School level hitter College Track & Field athlete, Jarrett – professional pitcher, Rookie in pro ball, home-run record holder at Div-1 college)
  • Took Full Swings prior to experiment swings (the Control group), so they could compare to when the lower half was restricted
  • Backspin Tee used on all swings (I know, shocker!)
  • Chair used to hit ball while falling
  • Pocket Radar to measure BES
  • Used 2 judges for checks and balances
  • Goal was to eliminate use of lower half
  • Every one used the same metal bat, a Copperhead C405 34 inch, 30 ounce (-4)

 

Data Collected

Based on control swings, this graph shows average BES as % of the control swings, Highest BES as %, & Lowest BES as % of each of the four hitters. Photo courtesy: BackSpinTee.com

 

Graph shows top BES per hitter on control swings, when Stationary No Hips, when Jump Float No Hips, Falling Float No Hips, Lead Leg Only No Hips, and Avg. BES. Photo courtesy: BackSpinTee.com

 

Data Analysis & Conclusion

Small sample sizes can cause a lot of problems, so there definitely needs to be more data points to make a conclusive decision.  However, with the data we have, the fact four different hitters participated on all swing experiments, in looking at the last graph, you can see that when the lower half was restricted, Ball Exit Speeds were around two-thirds of top exit velocity of control swings (normal swings).  Think Jeter making his jump throw!  So from this small sample size, we can say the lower half contributes about one-third to the Exit Speeds of these four hitters.

Question: Do “Squish the Bug” Baseball Swing Mechanics Depress Bat Speed?

 

Baseball Swing Mechanics Experiment: TylerD

Here are the two test swings from my intern for the summer, redshirt college Frosh, Tyler Doerner…

Using the Zepp (Labs) Baseball app, I wanted to use the Scientific Method to analyze if the baseball swing mechanics “squishing/squashing the bug”, during the turn, increases or decreases bat speed.  The term “squishing the bug” means rotating the back foot, on the ground, during the turn.  Like you’re squishing a bug.

This can be a very sore subject, and hotly debated with a passion, in the Church of Baseball.  Surprisingly, it’s still widely taught throughout the lower levels.  Although a few images off the internet of effective swingers like Cano, Bautista, McCutchen, etc. will reveal “squishing the bug” isn’t what the best are doing.

So we wanted to test it…

My intern for the summer, redshirt college freshman Tyler Doerner did this experiment.  This post is for you Joe (you know who you are ;-)…

Background Research

One of the main objectives of whether to skip the foot, or keep it on the ground, has to do with transferring linear momentum, better known as un-weighting or forward momentum.  Check out these four HPL posts for a baseball swing mechanics background on this:

  1. Troy Tulowitzki Zepp Swing Experiment: Stride Killing Bat Speed?
  2. Ryan Braun: Common Mistakes Hitters Make #1
  3. Baseball Hitting Video: Gain Distance the Easy Way PART-1
  4. Perfect Swing Hacking with Forward Momentum (feat. Mike Trout)

Now, for you academics, CLICK HERE to watch a short 2-minute PBS video on Circus Physics and the Conservation of Linear Momentum.

So, after reading/watching the above videos and posts, we should be at a common understanding of Forward Momentum.

The next objective of “squishing the bug” versus “skipping the back foot” during the turn, boils down to allowing the body to transfer energy effectively.  This has to do with springy fascia in the body…

In Thomas Myers’s book Anatomy Trains, he talks about a cotton candy like springy material that the bones and muscles float it, and what gives muscles their shape called fascia.

Specifically in the book, he talks about the Front & Back Functional Lines.  CLICK HERE for a post I did on this, featuring Ted Williams and Matt Kemp.

In the following video, Thomas Myers explains this idea of Tensegrity, or Tension-Integrity.  There are compression and tension forces acting on the body at all times.  Within the body these two opposing forces are always searching for balance…

For a hitter, if the body moves forward, but the back foot and leg stays behind, then these forces don’t get optimally transferred from body to barrel to ball.  In other words, the backside gets “left behind”.

Hypothesis

Based on the above research, I think “squishing the bug” baseball swing mechanics will have a depressing effect on bat and hand speed because it doesn’t allow for full transfer of momentum and release of elastic energy in the springy fascia.

 

“Squish the Bug” Baseball Swing Mechanics Experiment

Equipment Used:

Setup:

  • Forward momentum was taken out of this baseball swing mechanics experiment by hitting from a 1-2 second pause at landing
  • Back two “baseball markers” were set at about 3 baseballs apart
  • The two tests in the experiment were counter-balanced.  Which consisted of eight blocks of 25-swings done in the following order ABBA BAAB.  Say “squish the bug” was letter ‘A’, and “skipping back foot’ was letter ‘B’.  200 total swings were completed in the experiment, 100 per test.  Counter-balancing helps remove the “getting tired” and “not being warmed” up factors.

 

Data Collected (Zepp Baseball App):

Squish the Bug Baseball Swing Mechanics Experiment

There were significant changes in Average Bat & Hand Speed, Time to Impact, and surprisingly, the hitter’s Attack Angle in this baseball swing mechanics experiment…

Data Analysis & Conclusion

  • +8-mph difference in average Impact Bat Speed, siding on “Skipping Back Foot”,
  • +3-mph difference in average Hand Speed Max, siding on “Skipping Back Foot”,,
  • -0.019 difference in average Time To Impact, siding on “Skipping Back Foot”, and
  • +4-degree difference in average Attack Angle, siding on “Skipping Back Foot”.

 

Notes

  • I think the “Squish the Bug” baseball swing mechanics experiment results were overwhelmingly clear.
  • Tyler did not technically keep his back foot posted to the ground during the “squish the bug” tests, so there still was an element of un-weighting going on with his backside.
  • In which case, measuring Ball Exit Speed (or how fast the ball came off the bat) may have netted interesting data to consider, compared to Impact Bat Speed.  However, with the results with the other readings of Avg. Hand Speed, Time To Impact, and Attack Angle, I think we can put the “Squish the Bug” baseball swing mechanics myth to bed 😀
  • The data and results suggests that when a hitter “leaves behind their backside”, there’s a slowing down of forward momentum, and the body naturally decelerates because the springy fascia is forced to stretch, but not release.
  • Keep in mind what I call the Goldilocks Syndrome.  The back foot can skip too far (porridge too hot), and it can also not skip at all (porridge too cold).  We want the back foot to skip just right.

The Bottom Line?

In this “Squish the Bug” baseball swing mechanics experiment, “Skipping the Back Foot” showed a notable difference in average Bat & Hand Speed, Time To Impact, and the hitters Attack Angle.  I want to encourage you to tinker and test this for yourself.  The objective of these swing experiments is to put modern hitting theory to the test, literally.  We NEED to test based on data, not feelings.  Share these results with friends.

Create Pre-Turn Hand Tension Like Babe Ruth

 

What is the proper youth hand bat grip for right and left-handed baseball softball hitters? Is door knocking knuckles the correct hold or is the “box” grip better.  I’d argue the gorilla grip is best, evidenced in this swing experiment.

Babe Ruth Reveals Hand Tension?

Look at the hands of Babe Ruth… Photo courtesy: PhotoBucket.com (user: BillBurgess)

Question: Do Relaxed Hands Really Lead to Higher Bat Speeds?

Using the Zepp knob sensor which you can’t get anymore, so instead grab a BlastMotion sensor.  I wanted to use the Scientific Method to analyze whether having relaxed hands or “hand-tension” – pre-turn – increases or decreases bat speed.

Background Research

To me, it just always looked like the all-time greats – Babe Ruth – were squeezing the handle of the bat into sawdust before going into their turn.  I’m basing this experiment off the following research and study:

1. Pavel Tsatsouline

From the Tim Ferriss podcast titled, “Pavel Tsatsouline on the Science of Strength and the Art of Physical Performance“, where Tim interviews Pavel.  Pavel trains elite athletes and military but is best known for commercializing the use of the kettlebell in America.

In the podcast, Pavel talks about how the hands can be used to recruit more muscle tissue and connect larger areas of the body.

2. Homer Kelly

In his book, The Golfing Machine, Homer Kelly talks of four power accumulators…in particular, the first power accumulator (p.70 in the 7th edition):

“…is the Bent Right Arm – the Hitter’s Muscle Power Accumulator.  Even though the Right Biceps is active, the Backstroke is always made with the Right Arm striving to remain straight.  But the straight Left Arm restraints this continuous Extensor Action of the right triceps with an effortless Checkerin Action.  Consequently, during Release, the Right Arm can straighten only as the Left Arm moves away from the Right Shoulder.  This results in a smooth, even Thrust For acceleration of the Lever Assemblies from an otherwise unruly force.”

3. Front Arm Fascial Lines

Thomas Myers talks about Front Arm Fascial Lines in his book Anatomy Trains.  These lines travel from the bottom three fingers (pinky, ring, and middle), across the chest, to the bottom three fingers of the opposite hand.  It’s these three fingers that connect these springy fascial lines found within the torso to whatever we hold in our hands.  It’s this hand tension, or finger pressure, that has fixed stubborn bat drag issues in my own hitters.

 

Hypothesis

Because of the previously mentioned research, I think the swing with Babe Ruth “hand-tension” will result in higher bat speed, and possibly other performance metrics, like max hand speed, time to impact, etc., that will be measured using the Zepp Baseball App.

Babe Ruth: “Hand-Tension” Experiment

Babe Ruth Hand-Tension Experiment Setup

Here was how I setup my experiment “workstation”

Equipment Used:

  • Zepp Baseball app (BlastMotion),
  • ATEC Tuffy Batting Tee (we use Backspin Tee now),
  • Rawlings Official NCAA Baseballs,
  • Two yellow dimple baseballs (feedback markers),
  • Flip Video Camera and Tripod, and
  • 33 inch, 30 ounce Pinnacle Bamboo bat.

Setup:

  • Yellow dimple ball feedback markers = my bat length, plus two baseballs
  • Distance from plate = end of the bat touching inside corner of plate, and knob of bat touching my mid-thigh.
  • Tee was set slightly behind the front feedback marker, and tee height was about mid-thigh.
  • First 100 baseballs were hit WITHOUT pre-turn “hand-tension”.
  • Second 100 baseballs were hit WITH pre-turn “hand-tension”.

Data Collected (Zepp Baseball App):

Babe Ruth Hand Tension Experiment Results (Zepp)

Check out the difference in average Bat Speed and average Time To Impact…

 

Data Analysis & Conclusion

Babe Ruth Hand Tension Experiment

Look at the difference in the Bat Vertical at Impact and Attack angles. This is the reason for the higher Fly Ball & Line Drive percentages…

When using pre-turn Babe Ruth “hand-tension”:

  • +3 mph average bat speed
  • Higher Max Bat Speed numbers
  • More horizontal bat angle at impact (matching pitch plane)
  • +6 degrees in attack angle
  • More productive outcomes (line-drives & fly-balls).

Notes

  •  I had trouble finding a proper slot for my hands WITHOUT pre-turn hand tension.  With it, I found more consistency with “educated” pre-tension Babe Ruth hands.
  • In the video, you can clearly see a better barrel launch angle when I had pre-turn “hand-tension”.
  • In the video, you can see an earlier barrel on the pitch-plane (probably as a result of the better barrel launch angle).
  • WITHOUT hand tension, my Zepp bat speeds swung wildly from swing to swing.  Whereas with pre-turn hand-tension, my bat speed numbers were more stable, staying within the 72-78 mph range.
  • I warmed up using the ProHammer bat, to prime my swing to not roll over when I started the Experiment.  Interesting to note that WITHOUT pre-turn hand tension, I began rolling over for the first 10-15 swings.
  • My upper half felt much more connected during the swing when I had pre-turn hand-tension.
  • The -1 degree vertical angle at impact was a much better improvement using pre-turn “hand-tension”.  Now, most of my Line Drives were about 8-12 feet off the ground.  My back foot was drifting forward a little much, so taming that and maintaining a 90-degree angle with the back leg, would push that vertical angle at impact even lower.  And as a result, would angle my drives up more.

The Bottom Line?

The Babe Ruth Pre-Turn “Hand-Tension” Experiment highlighted what Homer Kelly calls “educating the hands”.  This Experiment suggests that the old dogma of keep your hands “loose” before you turn holds no water.  This is another example of backwards thinking that’s been taught for decades.  All my hitters, from pro and college to Little League, say how much more bat speed they have when they use pre-turn “hand-tension”.  I urge you all to repeat the same experiment and report what you find in the comments below.  Test…Test…Test these dogmas, so we can finally put the ol’ dog to bed.

*EXPERIMENT UPDATE*: Thanks to my friend Lee Comeaux, who is a professional golf instructor, for further simplifying the finger pressure technique…have the hitter squeeze the bottom three fingers (pinky, ring, and middle) of the top hand ONLY, from the moment the hitter picks up their stride foot to all the way through impact.  This alone has cleared up stubborn bat drag issues with my hitters from TEN to SIXTEEN years old.





The toughest swing flaw to fix bat drag in youth hitters isn’t the one that looks the worst on video — it’s the one that looks fine at normal speed. A hitter with racing rear elbow swings hard. The barrel gets to the zone. And coaches watching from the third-base line miss it entirely until the weak flares and rolled-over grounders pile up.

This post covers the exact case study that changed how I approach bat drag: my local hitter Zach May, a 6’4″ sophomore in high school who had struggled with a racing rear elbow for over a year. In one 30-minute session using Reactive Neuromuscular Training (RNT), we eliminated the racing rear elbow — not just on one pitch, but across the board. Here’s everything we did, and the free drill sheet that goes with it. (In a hurry? Jump straight to the free Bat Drag Fix Drill Sheet ↓)

Two related posts worth reading first: Hitting Tips to Boost Barrel Time on Pitch-Plane and Never Suffer from Bat Drag Again. Both generated the most reader responses I’ve ever seen on this site — and both problems trace back to the same root cause we’re fixing here.

What is bat drag — and why do coaches call it a racing rear elbow?

Bat drag and racing rear elbow are the same flaw described from two different camera angles. Specifically, racing rear elbow is what it looks like from the front: the rear elbow races past the hands toward the center of the body before contact instead of staying behind them. In contrast, bat drag is what it looks like from the side: the barrel takes a wide, looping arc away from the body before entering the hitting zone, arriving late and at a shallow angle.

The result is a premature barrel dump. When the barrel dumps early, hitters either:

  • Flare or miss completely to the opposite field — the ball goes over the barrel because it has dropped out of the zone
  • Roll over or get jammed on inside pitches — the wide arc creates a natural handcuff effect

As a result, it’s a frustrating flaw to fix bat drag with conventional instruction because every upper-body cue — “keep your elbow in,” “stay connected,” “knob to the ball” — works in isolation and disappears under game-speed stress. Therefore, the fix has to come from somewhere else entirely — and I’ll show you exactly where.

What symptoms reveal a racing rear elbow bat drag problem?

Three lower-body symptoms appear consistently in rear-racing-elbow hitters — and none of them are arm problems.

In Zach’s case — and I’ve seen this cluster repeat across enough hitters to call it a pattern — those three things showed up in his swing:

  1. Front leg not getting to straight at or past impact. With a lot of forward momentum in his stride, Zach’s front knee was staying bent through contact instead of straightening. That matters more than most coaches realize — I’ll explain why in the next section.
  2. Back knee not reaching 90–105 degrees during the turn. The back knee angle is a pelvis rotation indicator. When it stays too straight or collapses too far, the hips can’t fully rotate, and the shoulders and arms pick up the slack — which is exactly how bat drag is born.
  3. Downhill shoulder angle before landing. Zach’s shoulders were getting level before he even landed, rather than staying in the slightly downhill angle that sets up the correct swing plane through the zone.

Most importantly, none of these are upper-body problems. They’re lower-body and hip problems that express themselves as a bat drag pattern in the arms. That’s why trying to fix bat drag by coaching the arms rarely sticks. You can read more on the connection in this post about top hand drills that address the bat drag pattern from a different angle.

How does front knee position affect your ability to fix bat drag?

Front knee position determines whether the pelvis can fully rotate — and incomplete pelvis rotation is the most common cause of bat drag in tall, high-forward-momentum hitters.

Whether the front knee should stay bent or straighten at contact is one of the more contested debates in hitting instruction. However, the answer depends entirely on forward momentum — and understanding that distinction is essential to figuring out why the bat drag showed up in the first place.

Hitters like Mark McGwire and Mark Teixeira — big, wide-base striders with less forward momentum — keep a slight flex in the front knee through contact, and it works. But hitters like Jose Bautista and Josh Donaldson, who drive significant forward momentum into their swing, need the front knee to go from bent at landing to straight through impact. That transition is what transfers energy from a forward (sagittal) plane to a rotational (transverse) plane using ground reaction forces.

Think of an NFL wide receiver running a 10-yard cut route. He’s moving at top speed (forward momentum), plants his foot, bends his knee, then straightens it explosively as he changes direction — using the ground to redirect his energy. Drop and turn. That’s the same mechanism a high-FoMo hitter needs. For a deeper breakdown of the planes of motion involved, Wikipedia’s anatomical planes of motion reference is a useful primer.

Zach is 6’4″ and uses a lot of forward momentum. When his front knee didn’t get to straight, his pelvis couldn’t fully rotate, his back shoulder and arm picked up the slack — and racing rear elbow followed every time. Fix the front knee timing, and the upper body problem resolves on its own.

One update worth noting: we’ve since moved away from treating front knee straightening as an absolute requirement across all hitters. Hitters like Bellinger, Seager, and Rizzo keep significant front knee bend on pitches below the belt line and still produce elite exit velocities. The principle applies strongly to high-forward-momentum hitters — not universally.

How do you run the RNT resistance band drill to fix bat drag?

Reactive Neuromuscular Training works by deliberately feeding the mistake rather than fighting it. Instead of telling a hitter to correct a faulty pattern, RNT applies resistance that exaggerates the pattern — triggering the body’s automatic, reflexive correction response. In other words, it’s a faster re-patterning method than verbal cues because the nervous system responds to sensory input more reliably than to instructions.

For more on the RNT framework, see this earlier post on how we used it with Dustin Pedroia’s “stepping in the bucket” correction — same principle, different problem.

Here’s the bat drag setup we used with Zach:

  • Two long resistance bands positioned as high up the thighs as possible (keep them above “the goods” to avoid injury). We used a heavier black band in front and a lighter red band in back, sourced from performbetter.com. A coach holds the front band; the back band is anchored.
  • Front band function: pulls the front leg backward, keeping the front knee bent — feeding the mistake. The hitter must resist by driving the front leg to straight, using ground reaction force.
  • Back band function: pulls the back leg forward, keeping the back knee from bending properly during the turn. The hitter must resist by driving the back knee to 90 degrees.
  • The hitter resists both bands simultaneously during the turn — which forces the pelvis to rotate fully and removes the conditions that create bat drag.

First, we broke the swing into two parts (load phase, then turn) before putting it together at full speed. The before-and-after comparison — both swings synced up 30 minutes apart — shows the elbow going from visibly racing ahead to pinned into the rib cage where it belongs.

Critical safety note: The person holding the front band is in the path of a swinging bat. This drill must always be facilitated by an adult coach who knows to clear the path. Do not run it as a teammate-to-teammate drill, especially with younger players who can’t stop their swing mid-motion.

Why does finger pressure fix bat drag when mechanics cues fail?

Even after the RNT drill produced visible improvement in Zach’s swing, the correction that made it permanent was simpler: finger pressure.

Finger pressure means squeezing the bottom three fingers of the top hand — hard — from the moment the front foot lifts, through the load, all the way to contact. That squeeze is what keeps the hands physically linked to the turning torso. Without it, a hitter can have correct hip rotation and front knee action, and the elbow will still race ahead — because the hands separate from the body during the turn.

The instruction is straightforward: “Bottom three fingers of the top hand — squeeze from foot-lift to contact.” Coaches often skip this cue because it sounds too simple. However, it addresses the bat drag at the exact point of failure: the connection between hand path and body rotation.

Related to this is wrist pronation — the active turning of the wrists through the hitting zone. This concept, which we explore through Hank Aaron’s wrist snap mechanics, naturally pins the rear elbow into the rib cage as a byproduct of the wrist action itself. In some hitters, pronation-focused training produces even faster results than the RNT drill alone.

Does wrist pronation fix bat drag faster than the RNT drill alone?

In some cases, yes. Wrist pronation — the active rotation of the wrists through the hitting zone at contact — naturally pins the rear elbow into the rib cage as a byproduct of the movement pattern itself. Hitters who respond better to feel-based cues than resistance-based training often get faster results from pronation work.

The practical cue is “turn the wrists over through the ball” — which sounds simple but requires the elbow to stay behind the hands for the pronation to work correctly. It’s a different entry point to the same correction. We cover this concept in depth in the Hank Aaron wrist snap post above. For hitters who keep reverting after the RNT drill, adding pronation drills in the same session dramatically improves retention.

Also worth noting: over-rotation is a bat drag trigger we see frequently when rotational mechanics are over-coached. If a hitter is being drilled repeatedly on “rotate more, rotate faster,” the compensation is often a racing elbow. Sometimes fixing bat drag means dialing back the rotation cue, not adding more work on top of it.

Both approaches — and the relationship between casting and the barrel path through the zone — are covered in depth in this post on what elite hitters actually mean when they shorten their swing. The two faults are closely related: casting and bat drag are often symptoms of the same root cause.

If bat drag is producing ground balls and weak contact, this overview of how to stop hitting ground balls covers the next layer of the fix — what the barrel does once the drag is corrected.

Frequently Asked Questions: Fix Bat Drag

What causes bat drag in youth baseball hitters?

Bat drag — called racing rear elbow — is caused by the rear elbow racing past the hands toward the body’s midline before contact. This dumps the barrel early and produces weak opposite-field contact or rolled-over pull-side grounders. The root cause is almost always incomplete hip rotation: when the hips can’t fully clear, the arms and shoulders compensate, and the elbow gets ahead of the hands. Front knee timing and back knee angle are the two most common contributors in high-forward-momentum hitters.

How do you fix bat drag fast without a hitting aid?

The fastest no-equipment way to fix bat drag is the finger pressure cue: squeeze the bottom three fingers of the top hand from foot-lift to contact. This keeps the hands physically connected to the turning torso and prevents the elbow from racing ahead even when hip rotation is correct. Add the RNT resistance band drill in the same session for the most durable correction. Both are included in the free Bat Drag Fix Drill Sheet above.

What is Reactive Neuromuscular Training (RNT) and how does it fix bat drag?

RNT deliberately feeds a movement mistake to trigger the body’s automatic self-correction. For bat drag, two resistance bands are positioned high on the thighs: one feeds the front-knee-stays-bent mistake, one feeds the back-knee-stays-straight mistake. The hitter resists both during the turn, forcing the correct pattern to emerge reflexively. The brain learns correct movement faster through sensory resistance than through verbal instruction — which is why a single 30-minute RNT session can produce changes that weeks of verbal coaching couldn’t.

Does the front knee have to straighten to fix bat drag?

It depends on the hitter’s forward momentum. High-FoMo hitters like Jose Bautista and Josh Donaldson need the front knee to go from bent at landing to straight through impact — this uses ground reaction forces to transfer energy from a forward plane to a rotational plane and allows the hips to fully clear. Hitters with less forward momentum (wide-stance, little-strider types) can keep more flex in the front knee and still rotate fully. The front knee check matters most when bat drag appears in a tall, aggressive-striding hitter.

What does finger pressure do to fix a racing rear elbow?

Finger pressure — squeezing the bottom three fingers of the top hand from foot-lift through contact — keeps the hands connected to the rotating torso. Without it, even hitters with correct hip rotation can show bat drag because the hands separate from the body during the turn and the barrel goes wide. The cue is the simplest fix in the kit, and it’s the one that tends to make RNT corrections permanent rather than temporary.

How long does it take to fix bat drag with the RNT drill?

In the Zach May case study documented here, racing rear elbow was visibly eliminated within one 30-minute session. Most hitters see measurable improvement in one to three sessions. The correction tends to hold best when the RNT drill and finger pressure cue are run together, and when the hitter understands the why — that bat drag is a hip rotation problem expressing itself in the arms, not an arm problem to be fixed in the arms.

Can you fix bat drag at home without resistance bands?

Yes. Finger pressure alone produces meaningful bat drag improvement with no equipment: squeeze the bottom three fingers of the top hand from foot-lift to contact on tee work, soft toss, or shadow swings. Wrist pronation drills — focusing on actively turning the wrists through the hitting zone — also address the pattern equipment-free. The free Bat Drag Fix Drill Sheet includes the at-home variation of the protocol so coaches and parents can run it without resistance bands.



Walk into any MLB stadium and you’ll see a completely different baseball batting stance in every single batter’s box. Ted Williams stood upright and compact. Tony Gwynn narrowed his stance late in his career and simplified everything. Derek Jeter spread wide and open. Josh Donaldson tweaked his setup more times than he can count. Today, Bobby Witt Jr. presets his hip before his stride, Freddie Freeman recently turned his front foot inward to close his hips, and Vlad Guerrero Jr. stands open to buy time on off-speed pitches. All of them are right. None of them look the same. And every one of them passes through the same five checkpoints that determine whether a stance actually works.

↓ Download the free 5-Point Stance Check PDF — or keep reading for the full breakdown.

What did Ted Williams say the proper baseball batting stance actually requires?

Ted Williams was the most analytical hitter who ever played the game, and he addressed the stance directly in The Science of Hitting. His requirements were precise: feet slightly wider than shoulder-width, a slight bend at the knees, a slight bend at the waist, hands near the back shoulder, and eyes level on the pitcher. Williams was specific about hand position in particular — “The further your hands are away from your body, the longer it takes to get into the proper load position.”

Additionally, Williams was dogmatic about one mechanical truth that made his five-point stance framework worth following: hips lead the hands. The purpose of the stance, in Williams’ view, was not to look a certain way — it was to create the conditions for full hip rotation. Weight shift alone, he argued, does not generate power. Hip rotation driven by the stance setup does. Therefore, the stance is not an aesthetic choice. It is the setup for the baseball swing load that generates everything that follows.

For youth hitters, Williams also gave important permission: experiment and find what feels comfortable within those five requirements. He was not advocating for one rigid model. He was identifying the non-negotiables that apply to every hitter regardless of style.

Tony Gwynn said the baseball batting stance doesn’t matter — so what does?

Balance. That was Tony Gwynn’s definitive answer on the batting stance debate, and it cuts through decades of coaching disagreement in one sentence. Gwynn was direct: “Your stance doesn’t matter, but if you’re not balanced by the time you load, you’re out.” He went further: “Balance and adjustability go hand in hand; without balance you really have no chance to adjust.”

This is arguably the most useful framing for youth hitters and coaches because it correctly identifies the stance as a means, not an end. The stance is how a hitter arrives at a balanced, adjustable launch position. Consequently, a wide stance, a narrow stance, an open stance, a closed stance — all of them can work, as long as the hitter achieves balance by the time the stride foot lands. A stance that looks textbook-perfect but doesn’t produce balance at landing is worse than an unconventional one that does. For a full breakdown of Gwynn’s hitting approach, Pro Baseball Insider’s Tony Gwynn hitting series covers his philosophy in depth.

How wide should your feet be in a baseball batting stance?

Shoulder-width to slightly wider is the most reliable answer, and it applies across virtually every elite hitter from Williams through today’s game. The exact width is secondary to what the foot position enables: a hip hinge, a loaded back hip, and a stable base for stride and weight transfer.

Josh Donaldson — who has changed his own setup more than a dozen times over his career — emphasizes what happens at the back hip. Donaldson teaches being engaged into the back hip, not the back knee: “When you are engaged in your back hip you have better balance than when you put all your weight into your back knee. When you are locked into your knee, you will naturally want to jump forward.” His weight setup focuses on the back heel and back hip working together — a subtle distinction that has major implications for load timing and hip rotation efficiency.

Bobby Witt Jr. takes that concept a step further with his hip preset. Before his stride, Witt’s belt buckle tilts slightly toward his back hip. This setup position means his hips are already primed to sequence before the stride foot lands — and when he does land, he arrives centered rather than drifting or rushing forward. That centered landing is what gives him the adjustability to cover all four quadrants of the zone. For more on how the back foot works in this equation, this breakdown of back foot angle and hip loading covers the mechanics in detail.

Where should your hands be in the baseball batting stance?

Near the back shoulder, close to the body. Williams said it plainly, and decades of swing analysis have confirmed it: the further the hands start from the back shoulder, the longer the path to the ball, the harder it is to generate bat speed, and the more likely the swing is to drag through the zone rather than accelerate through it.

Hand position in the stance also determines where the hands travel during the load. When hands start close to the back shoulder at the right height, the load is a compact internal rotation rather than a long reaching motion. That compact load is the difference between a short, direct swing and one that’s susceptible to bat drag — one of the most common swing killers in youth baseball. Furthermore, hands at shoulder height avoid the upward adjustment that occurs when the hands start too low and must travel upward to meet a fastball at the top of the zone.

Cal Ripken Jr., who changed his batting stance many times over his HOF career, consistently returned to one principle: learn yourself as a hitter. That self-knowledge includes understanding where your hands naturally fall at load — and whether that position is helping or hurting your path to the ball.

What are today’s best hitters doing in their stance that youth hitters can learn from?

The most instructive recent example is Freddie Freeman’s front foot adjustment in 2026. Freeman identified a problem — he was pushing balls to left field rather than driving them — and traced it to his hip opening too early in the swing. His solution was to turn his front foot slightly inward (like Corey Seager), which gave his hips a physical reason to stay closed longer before rotating through the ball. His quote on the result was simple: “Obviously that’s helped a lot.”

What makes this instructive for youth hitters is the diagnostic process. Freeman didn’t change his swing. He adjusted one element of his setup — front foot angle — and the downstream result was that his hips rotated more efficiently. That is exactly how stance changes should work: identify a specific problem, trace it to a specific setup element, make one targeted adjustment, and measure the result in ball-in-play data.

Bobby Witt Jr.’s hip preset is similarly instructive. Most youth hitters think of the stance as static — you set up, then you swing when the pitcher delivers. Witt’s approach treats the stance as an active, athletic position where the hips are already loaded before the stride fires. The result is that he gains ground toward the pitcher without losing tension in his rear hip, which gives him both direction and timing. Improving batting timing often starts with this exact principle — the stance isn’t passive, it’s the first movement in a sequence.

What coaches and players using the HPL system say

“13 year pro ball player here. I just wanted to say how much I enjoy your videos and emails — I couldn’t agree more with the mechanics and techniques you teach. You’re on the right track to unlocking what it takes physically and mechanically to translate what the best in the world are doing every day. Keep up the great work.”

TGARCIA247 ★★★★★ — 13-Year Professional Baseball Player

“Many of my hitters are starting to achieve exit velocities they never thought possible. Averages are up, power is up. I have three girls playing D1, six at D2, two going to JUCOs this fall — and I credit the HPL approach for proving the science and providing convincing evidence.”

Ronny Weber ★★★★★ — Baseball & Softball Coach

“Enthralled with your stuff — can’t even watch football in peace for watching, reading, and thinking hitting. Learning so much from the HPL approach, especially as it relates to what I’ve built my coaching on. Can’t wait to share this in the new year with my team. Now your number-one fan.”

The 5-point baseball batting stance check coaches use to diagnose problems fast

Across all the variation in elite batting stances — from Williams to Gwynn to Jeter to Freeman to Witt — five checkpoints remain constant. These are not preferences or style choices. They are the mechanical requirements that every effective stance must meet. Check all five and a hitter’s setup will work. Miss one and the rest of the swing has to compensate.

Checkpoint 1 — Balance

Weight should be roughly centered or slightly back at setup — not forward. Gwynn’s test applies: can the hitter hold the stance for three seconds without swaying? If not, the stance isn’t producing a stable launch position. Weight forward at setup means weight is already forward before the pitch, which eliminates any load and transfer.

Checkpoint 2 — Foot Width

Shoulder-width to slightly wider. Feet too narrow = limited hip rotation room. Feet too wide = restricted stride and hip mobility. The width should allow a full hip turn without the back foot flying out or the front knee collapsing inward. For stride mechanics tied to foot width, the setup and the stride length are directly related.

Checkpoint 3 — Hip Hinge

Soft knees with a slight bend at the waist. Standing too upright is the single most common youth batting stance error. An upright stance eliminates the athletic ready position — the same posture a shortstop uses when fielding, a basketball defender uses to stay in front of a ball handler. Without the hip hinge, there is nothing to rotate from.

Checkpoint 4 — Hand Position

Hands near the back shoulder, close to the body, at or slightly above shoulder height. This is the position Ted Williams prescribed. Hands too low create an upward path adjustment. Hands too far from the body create a longer, weaker swing. Check the baseball batting drills that reinforce this hand position through repetition.

Checkpoint 5 — Head and Eye Level

Both eyes on the pitcher, head still and level. This sounds obvious but is violated constantly when a hitter stands with their head tilted, chin buried in their shoulder, or eyes angled rather than level. A level head is a pre-condition for pitch tracking — the eye needs a stable platform to do its job. If the head is tilted in the stance, the visual field is already compromised before the pitch is thrown. For a full list of baseball hitting tips tied to each of these checkpoints, the library covers every piece in depth.

What is the most common baseball batting stance mistake youth hitters make?

Standing too upright is the most common and most damaging stance mistake in youth baseball. A hitter with no hip hinge and no knee bend has eliminated the athletic position that makes rotation possible. The stance looks casual — like someone waiting for a bus rather than preparing to swing at 85 mph. As a result, the only power source available is the arms and wrists, which is not enough against any pitcher with velocity or movement.

The second most common mistake is hands too far from the body. When the hands start extended — out away from the chest rather than close to the back shoulder — the load path is immediately longer. Furthermore, extended hands create a loop in the swing path as the hands have to travel inward before they can go outward to the ball. That loop is the origin of most bat drag problems, and it starts in the stance before the pitch is ever thrown.

The third mistake is weight too far forward. Some hitters set up with their weight already on the front foot before the pitch. This eliminates the weight transfer that feeds hip rotation. Without weight moving from back to front during the swing, there is no transfer of energy — and without energy transfer, there is no power regardless of how sound the rest of the mechanics are. Think of it like a pitcher who plants their front foot and tries to throw without using their legs. The arm still works, but the velocity disappears.

Common questions about the baseball batting stance

What is the proper baseball batting stance for youth hitters?

The proper baseball batting stance for youth hitters is an athletic ready position with feet shoulder-width or slightly wider, a soft bend at the knees and waist, hands near the back shoulder at approximately shoulder height, and eyes level on the pitcher. There is no single correct stance — Tony Gwynn, Ted Williams, and Derek Jeter all looked different. What they shared was the same five checkpoints at stride landing: balance, foot width, hip hinge, hand position, and head level.

How wide should my feet be in a baseball batting stance?

Feet should be shoulder-width or slightly wider. Ted Williams recommended feet slightly wider than shoulder-width. The exact width depends on body type and stride length — a hitter with a longer stride starts a bit narrower, while a no-stride hitter may stand wider by default. The critical requirement is that the width allows a full hip turn without the back foot flying out or the front knee collapsing.

Where should your hands be in the batting stance?

Hands should be near the back shoulder — at shoulder height and close to the body. Ted Williams wrote in The Science of Hitting that the further hands are from the body, the longer the path to the load position. Close hands create a short, direct swing. Extended hands create a longer path and increase bat drag through the zone.

Is a closed or open batting stance better?

Neither is universally better. Derek Jeter used an open stance for 20 seasons. Freddie Freeman adjusted to a more closed front foot in 2026 specifically to keep his hips from opening too early. The starting foot angle is less important than where the hitter lands at stride — balanced, with the front foot roughly squared and the hips still loaded. Both open and closed stances can achieve that landing position.

What did Ted Williams say about the proper batting stance?

Williams outlined five requirements in The Science of Hitting: feet slightly wider than shoulder-width, soft knees, slight bend at the waist, hands near the back shoulder, and eyes level. He also taught that hips lead the hands — the stance must enable full hip rotation, not just weight transfer. And he gave young hitters explicit permission to find their own comfortable version of these fundamentals rather than copying one specific model.

Why do elite hitters have such different stances if there’s a proper one?

Elite hitters look different in their stances because the pre-pitch setup is personal — it reflects body type, timing preference, and rhythm. However, all elite hitters pass through the same five checkpoints at stride landing. At that moment, balance, hip hinge, hand position, foot alignment, and head level are consistent across virtually every elite MLB hitter. The stance is individual. The launch position is universal.

How does batting stance affect power and contact?

Batting stance affects power primarily through hip hinge and hand position. A stance with soft knees and a slight bend at the waist enables hip rotation — the primary power source. A stance with hands close to the back shoulder enables a short, direct path that improves contact rate. The three most common stance faults that reduce power and contact are standing too upright, hands too far from the body, and weight too far forward.

Jose Altuve Hitting Analysis Reveals A Pathway To Repeatable Power

 

Jose Altuve Hitting Analysis

Learn how to increase hitting power stats like Jose Altuve swing with fundamental baseball and softball drills in 2022.

In doing Jose Altuve hitting analysis, here’s what I hear…

“Well, he’s a big hitter, that’s why he can hit for power”…

…Is the EXCUSE from coaches who’re removing any responsibility to help their smaller hitters hit the ball farther and harder.

Or, oftentimes I hear this about a hitter like Dustin Pedroia (5’9″, 175-lbs – these numbers are fudged “up” btw):

“He’s just gifted.”

Wa?!!

ALL Major Leaguers are GIFTED!!! lol

Tell me one physical advantage that Dustin Pedroia has over most…??!

Don’t say eye hand coordination or vision because that’s another common rebuttal.

There are countless other MLB hitters with the same superior eye-hand coordination and vision.

The reality is, smaller sluggers MUST be MORE effective, in order to compete with sluggers bigger than them.

Now, this Jose Altuve hitting analysis post isn’t about the ‘laser show’…however,

Standing in at 5’6″,

…and weighing in at a soaking wet 165-pounds, we’ll look at Jose Altuve (his height and weight numbers are a little closer to reality I think).

Although,

I do think Jose Altuve has one thing over the ‘laser show’, and that’s dancing (parental guidance is recommended 😉:

In this Jose Altuve hitting analysis video, we’ll go over:

  • Jose Altuve stats,
  • Presents of Forward Momentum (FoMo)?
  • How well he dominates the plane of the pitch,
  • Where his power comes from, and
  • Does he practice Pitch Recognition?

FYI: the pitch Jose Altuve is hitting in the video analysis looks like an 87-mph FB straight down broadway, and it does look like he’s on-time.

Without further adieu, here are the notes for the…

 

Jose Altuve Hitting Analysis Stats (the averages of averages)

CLICK HERE for the FanGraphs.com post  I pulled the following stats from*:

  • ISO = +20 points
  • BABIP = +34 points
  • GB% = +4%
  • LD% = +1%
  • FB% = -6%
  • HR/FB% = -3.5%

(*a (+) denotes how many points OR percentage points or above league average, and a (-) denotes below league average.)

 

Presents of Forward Momentum (FoMo)?

  • Is FoMo present?
  • Shifting foot pressure (mentioned landing with closed front foot), and
  • Moving Center of Gravity (COG).

 

How Well he Dominates the Plane of the Pitch

  • Knee Action – ‘getting shorter’ and ‘staying shorter’
  • Barrel Plane – keeping barrel on plane for as long as possible

 

Where his Power Comes from…

  • Showing numbers,
  • Hiding hands from the pitcher,
  • Hunch – Posterior Pelvic Tilt (PPT), and
  • Down shoulders? (not so much here).

 

Does he Practice Pitch Recognition?

My friend Aaron Miles, who was small (5’8″, 180-lbs), and played 9 years in the Bigs, talks about how his High School coach was forward thinking…in that he did Pitch Recognition training with his troops, and Aaron’s coach said he had the best PR on the team.

My hypothesis in this Jose Altuve hitting analysis is that he does some sort of PR training, OR has a God given early pitch recognition ability that allows him to hit the ball so hard, so often.

Sure, according to this Jose Altuve hitting analysis,

…Altuve may not hit over 30 homers per year, but he sure will hit a boat load of doubles, which is just as good to contributing to team wins…just look at his above average (average) ISO and BABIP scores above!
