Zepp Swing Experiment Attempting To Put Value On Role Of Pelvis In Swing
Question: How Much Does Pelvis Add to Bat Speed at Impact?
According to InnerBody.com, the pelvis is a sturdy ring of bones that protects the delicate organs of the abdomino-pelvic cavity while anchoring the powerful muscles of the hip, thigh, and abdomen. Several bones unite to form the pelvis, including the sacrum, coccyx (tail bone), and the left and right coxal (hip) bones. Photo courtesy: OrthoInfo.aaos.org
Using the Zepp (Labs) Baseball app, I wanted to employ the Scientific Method to analyze how much turning the pelvis (some refer to this as the hips) adds to Bat Speed at Impact. The ‘Front Facing Swings’ are an attempt to isolate out the role of the pelvis in the swing, so we can analyze how much the pelvis adds to swing performance.
Just a heads up, the “pelvis” and “hips” are not the same thing. The hips are a small part of the pelvis. However, most coaches refer to “hips” when instructing the swing, when most likely they mean “pelvis”.
SCIENCE-BASED TRAINING:
Improve your hitting strategy dramatically by applying human movement principles.
Learn not only how and what to train but also the science behind the methods.
For those coaches with a Growth Mindset that want to find out more about the science of locomotion. I’d recommend reading the following technical books:
If working through the weeds isn’t for you, then you can click the following HPL posts that synthesize the information contained in the previously mentioned books:
I’ve done two swing experiments revealing the role of the shoulders in the swing that tested the value of ‘Showing Numbers’ versus ‘NOT’. These showed an average increase to Bat Speed at Impact – Showing Numbers – of between 5 to 6-mph. In addition, one of the experiments showed an average increase to Ball Exit Speed of over 9-mph ‘Showing Numbers’! That’s between 38 to 48-feet of ADDED batted ball distance by ‘Showing Numbers’:
This Zepp swing experiment is attempting to put value on the role of the pelvis in the swing.
Hypothesis
Ted Williams, in his book The Science Of Hitting, said the ‘hips lead the way’. This observation is irrefutable when watching slow motion video of elite hitters. A majority of coaches teach primarily a ‘hips only’ strategy, which I disagree with. I feel ‘firing the hips’ is over-taught and over-valued, while the role of the shoulders is under-taught and under valued. The objective of this experiment is to see what benefit the pelvis (or hips) add to swing performance.
I predict ‘Regular Swings’ will have a substantial increase in Bat Speed at Impact than the ‘Front Facing Swings’.
Performance Benefit of Pelvis Swing Experiment
Equipment Used:
Zepp Baseball app (to measure Bat Speed, Hand Speed, Time to Impact, & Attack Angle),
Yellow dimple ball feedback markers to keep starting footwork the same = bat length…I used two yellow dimple ball markers to make my stance setup consistent. One was placed inside my back foot, close to the plate. The other was placed one bat’s length ahead of the back marker.
Tee was set one baseball’s length behind the front feedback marker, and tee height was about mid-thigh
We stayed as consistent as we could with keeping the ball height and depth the same for most swings.
The two tests in the swing experiment were counter-balanced. Which consisted of eight blocks of 25-swings done in the following order ABBA BAAB. ‘Front Facing Swing’ was letter ‘A’, and ‘Regular Swing’ was letter ‘B’. 200 total swings were completed in the experiment, 100 per test. Counter-balancing helps remove the “getting tired” and “warm up” factors.
The objective of ‘Front Facing Swings’ was to start the ‘belt buckle’ pointing at the pitcher, and to minimize pelvic movement.
Experiment Day-1 on 6/19 we completed 75 total swings (25 ‘Front Facing’ & 50 ‘Regular’). Experiment Day-2 on 6/26 we completed 125 swings (75 ‘Front Facing’ & 50 ‘Regular’).
We had to break the 200 total swings into two days, with the second day coming 1 week later, because of time constraints.

‘Regular Swing’ AVERAGES for the following metrics: 81.5-mph Bat Speed at Impact, 33-mph Hand Speed Max, 0.130-secs Time To Impact, -28.5* Bat Vertical Angle at Impact, & 0* Attack Angle.
Data Analysis & Conclusion
Zepp data analysis comparing the averages of averages:
4.5-mph INCREASE to Bat Speed at Impact in ‘Regular Swings’,
3-mph INCREASE to Hand Speed Max in ‘Regular Swings’,
0.047 DECREASE to Time To Impact in ‘Regular Swings’,
-4-degree DECREASE to Bat Vertical Angle at Impact in ‘Regular Swings’, and
-3-degree DECREASE to Attack Angle in ‘Regular Swings’.
Notes
The increase in Bat Speed at Impact and Hand Speed Max confirmed my hypothesis, and didn’t surprise me since the first piece of The Spinal Engine to interact with Gravitational Forces is the pelvis.
It’s also interesting to note, that you can see from the side-by-side video of the swing, that I wasn’t able to keep the “belt buckle” ‘front facing’ as much as I would have liked to on ‘Front Facing Swings’, so possibly the pelvis could have added a bit more. I was feeling inside right knee tightness when forcing pelvis to stay facing forward.
The DECREASE in Time To Impact with ‘Regular Swings’ could have been due to the increased step and/or unfamiliarity with the movement, while doing ‘Front Facing Swings’.
In past swing experiments testing ‘Down Shoulders’ and ‘Showing Numbers’ I increased my Attack Angle – in the positive. I think the 3-degree increase in positive Attack Angle for ‘Front Facing Swings’ was due to better execution of those elements.
We were testing Ball Exit Speed in the beginning but had equipment malfunction (batteries went dead). I was too many swings in when the equipment was fixed, so we threw BES out in this experiment. I’d love to see BES measured in a future review of this swing experiment.
One last thought, because my pelvis inwardly turned toward the catcher – drastically – on ‘Front Facing Swings’, we saw quite a drop-off in production. Does this give evidence that an inward turn before the swing may be inferior to keeping the pelvis in neutral (or belt bucket facing plate)?

Paul Goldschmidt: Can a Bleeding Barrel Kill Hitting Potential?
My 9yo hitter Collin bleeding his barrel. Swings are synced, before (on the left) & after (on the right)
In this video, we’ll look at 2013 National League MVP runner up Paul Goldschmidt’s swing and relate it to one of my younger hitters. We’ll talk about:
What is a bleeding barrel (1-week before & after case study),
The “Goldy” standard, and
How-to fix a bleeding barrel at home.
What is a “Bleeding Barrel” (1-week before & after case study)
I’ve been working on this with one of my young hitters, Collin. Bleeding the barrel is when the barrel starts to launch (turn into the hitting zone) before the hitter’s front foot touches down.
It’s caused by a premature turning of the shoulders, and is very inefficient when it comes to transferring energy. In order to load powerful springy fascia and connective tissue in the torso, the front shoulder must stay in and down towards the back hip, at front foot touch down. CLICK HERE for similar analysis comparing Josh Donaldson (Oakland A’s) to Jose Bautista (Toronto Blue Jays).
The week following my young hitter Collin’s AFTER video, he was bleeding his barrel again. The cause? His dad said a coach was doing rapid-fire soft toss before games. Needless to say, Collin’s dad had a talk with the coach.
SCIENCE-BASED TRAINING:
Improve your hitting strategy dramatically by applying human movement principles.
Learn not only how and what to train but also the science behind the methods.
Notice Paul Goldschmidt (pictured to the right) at front foot touch down:
His barrel angle is up (70-degree angle), and
He’s showing his numbers to the pitcher (see video above).
Most importantly, taking care of point #2 above will stop the bleeding barrel.
Can Paul Goldschmidt do better? According to Baseball-Reference.com, he stands at 6’3″, and weighs 245 lbs. With this line, he can get away with inefficient mechanics and still hit for decent power. His average home-run total per 162-game season is only 29. For how big he is, he can average over 40 homers per season.
Here are a couple things I’d love to see change in Goldy’s swing:
More forward momentum,
Better down shoulder angle (side bending in the spine),
Hide his hands a little more from the pitcher, and
Extend up and back over the catcher more (he was a little out front on this pitch).
How-To Fix a Bleeding Barrel at Home
Remember to use Variance in the following scenario. Three steps to stop the bleeding barrel:
Break Swing into 2-Steps (1-2 second pause between): 1) Fight Position (landing), and 2) Final Turn – focus on showing the hitter’s numbers to the pitcher at the Fight Position, and keep a barrel angle around 45-55 degrees.
Check-Swing Drill – get hitter to show they can keep from bleeding the barrel to impact.
Put Swing Together – once they get here, then progress them from tee, to soft toss, to LIVE batting practice. If they can hold together their mechanics, then the brain has ingrained the movement.

The Anatomy Of A Game Winning Justin Turner Walk Off Homerun
To be honest with you…
I MISSED watching the Justin Turner walk off homerun LIVE!!
My excuse…?
For those of you who can remember when your kids were 2-5 years old, you might recall the Disney channel being on almost constantly in your household.
When I turn on baseball, I get “Why are we watching this…?” from my 5yo. And not after 30-mins of it being on…no…RIGHT AWAY!
He could be drawing, watching a kid’s show on his Kindle, or playing with his NERF gun, and he knows when the channel is changed. It’s like he knows it’s going to happen before it does. That’s another talk for another day.
But I digress…
I did get to see the replay of the game winning dinger via Twitter…
And, I DO know this, Justin Turner’s walk off homerun was a thing of beauty.
As many of you know, I get a lot of Fixed Mindset knuckleheads claiming this system doesn’t work at the higher level on the socials…in baseball and softball circles.
I blame the lenses they look at hitting through, which – let me tell you – are far less effective than picking up a bar fly with “beer goggles”.
Seriously though, here’s some context to put the dinger in perspective, before getting to the info in the video above…
I know, shocker for a select few out there. I do define some of the above terms in the video, so make sure you watch that before commenting. I know some of the cues can be used with the right framing of it.
So let’s see…
What he IS Doing
Catapult Loading System principles: globally flexed spine, hiding hands, showing numbers, and
Pitch Plane Domination: knee action, back foot skip, early barrel on pitch plane, barrel stays on plane for long time, great spine angle at impact.

Just FYI, on this Friday, October 20th, I’m giving away free Kindle versions of my new bookThe Catapult Loading System: How To Teach 100-Pound Hitters To Consistently Drive The Ball 300-Feet…but here’s the catch, this giveaway is for 5-days ONLY! Last time I did this, over 1,300 coaches and parents downloaded the ebook. And you don’t have to have a Kindle to read the book, just download the Kindle app on your mobile device. If you’ve already downloaded it, then I’d appreciate it if you could let a friend know. Literally hundreds of coaches across the States are getting the same results – if not better – with their hitters (literally THOUSANDS of them!!) using this system, than I am with mine. I’ll make the announcement over email and Facebook, so please look out for that in a couple days…

Discover the best BBCOR or USSSA baseball bats for power and contact hitters in 2022 or 2023 based on price. Learn whether an under $200 bat outperforms it’s more expensive counterpart in this swing experiment. For fastpitch and slowpitch softball, it’s crucial to discern this fact. What about end-loaded BBCOR drop 3 versus USSSA drop 10?
Question: Do More Expensive Bats Increase Bat & Ball Exit Speeds?
In this baseball batting practice Mizuno bat model experiment using the Zepp (Labs) Baseball app & Bushnell radar gun, I wanted to use the Scientific Method to analyze what would happen to Bat and Ball Exit Speeds comparing the performance of two different Mizuno bat models, but the same 34-inch, 31-ounce size:
According to the Mizuno website, the focus of this bat is maximizing Ball Exit Speed and backspin. Some key features are (Mizuno site):
Viscoelastic Sleeve: Creates a wider circumferential sweet area.
New Variable Wall Thickness Alloy Core: Increases the sweet area across the length of the barrel, using aircraft aluminum alloy used to keep overall weight low.
Dynamic Damper: Transition piece from barrel to handle absorbs vibration for better feel.
New Improved Synthetic Leather Grip: Provides tack and great feel.
Lower more balanced swing weight for increased swing speed.
BBCOR certified, approved for NCAA & NFHS play
Barrel Diameter: 2 5/8″
SCIENCE-BASED TRAINING:
Improve your hitting strategy dramatically by applying human movement principles.
Learn not only how and what to train but also the science behind the methods.
According to Mizuno’s site, the Mizuno Generation baseball bat was designed with two things in mind:
A bigger sweet spot, and
Balance – (lighter swing weight, which can result in faster bat speeds).
Key features of the baseball batting practice Mizuno Generation bat (Mizuno site):
Patented wall thickness technology varies the wall thickness across the barrel, creating a massive sweet area for ultimate forgiveness
Single wall aerospace grade aluminum alloy used for maximum combination of performance and durability
Balanced swing weight for increased swing speed and bat control
Digi-Grip for great feel and durability
BBCOR certified, approved for USSSA
Barrel Diameter: 2 5/8″
Another factor in this baseball batting practice Mizuno bat model experiment will be breaking in a non-wood bat. CLICK HERE for a good YouTube video on how to break-in a composite bat. Now, both Mizuno bats are not composites, but I’m sure the breaking in process with any alloy, will have an affect on Ball Exit Speeds.
We’ll adjust the data to address breaking in the bat in the Notes section.
Hypothesis
Based on the above baseball batting practice Background Research from Mizuno (albeit promotional materials), and the fact the MaxCor is double the price, I’d expect a much better performance in Bat and Ball Exit Speeds using the MaxCor model bat versus the Generation.
Baseball Batting Practice: Mizuno Bat Model Experiment
All baseball batting practice swings were taken off the tee.
I used two yellow dimple ball markers to make my stance setup consistent…one was placed inside my back foot, close to the plate. The other was placed one bat’s length plus two baseballs in front of the back marker.
CLICK HERE for the Google Drive excel document with all the Ball Exit Speed (BES) readings.
We deleted radar gun mis-reads that registered below 30-mph on the gun.
Therefore, we deleted 11 mis-reads from the Mizuno MaxCor bat data, and averaged all MaxCor BES readings to 89 swings.
Also, we deleted 7 mis-reads from the Mizuno Generation bat data, and averaged all Generation BES readings to 93 swings.
The two tests in the experiment were counter-balanced. Which consisted of eight blocks of 25-swings done in the following order ABBA BAAB. Swinging the “Mizuno MaxCor” were letter ‘A’, and
“Mizuno Generation” were 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.

According to the Zepp app, the Mizuno MaxCor came out supreme in all areas except the Attack Angle…
Data Analysis & Conclusion
ZEPP READINGS:
Avg. Bat Speed at Impact increased by 3-mph using the Mizuno MaxCor,
Avg. Max Hand Speed increased by 2-mph using the Mizuno MaxCor,
Avg. Time to Impact decreased by 0.063,
Avg. Bat Vertical Angle at Impact decreased by 1-degree using the Mizuno MaxCor, and
Avg. Attack Angle decreased by 4-degrees using the Mizuno MaxCor.
BUSHNELL BALL EXIT SPEED READINGS (CLICK HERE for Google Excel Doc):
Avg. Ball Exit Speed increased by 4.6-mph using the Mizuno Generation bat,
Top out Ball Exit Speed was 95-mph using the Mizuno Generation bat, and
Top out Ball Exit Speed was 90-mph using the Mizuno MaxCor bat.
Notes
Now, we can’t compare apples to apples baseball batting practice data using the Zepp app and Bushnell radar gun. If I had one more Bushnell radar gun capturing my bat speed readings perpendicular to my chest, then that would’ve been an interesting comparison.
I felt much more balance with the Mizuno Generation. I also felt like I was more consistently hitting the sweet spot, as their marketing suggests. For some reason it was tough feeling a consistent sweet spot using the MaxCor, maybe because of the “Dynamic Damper: Transition piece from barrel to handle absorbs vibration for better feel”.
It takes about 100-200 swings to break in a non-wood bat, at least according to the following YouTube video on How-To Break-in a Composite Bat. I’m going to share a Zepp app screenshot comparing the first 100 swings using the Mizuno MaxCor (from this experiment), to the first 100 swings using the Mizuno Generation (from the Baseball Swing Tips: Mizuno Bat Size Experiment):
Look at the near identical performance Zepp data between the two bats when we compare their first 100 swings…
How about comparing the Ball Exit Speeds of the first 100 swings…according to this Google spreadsheet, the Mizuno MaxCor Avg. Ball Exit Speed was: 83.5-mph. And according to this Google spreadsheet from a couple weeks before, Avg. Ball Exit Speed using the Mizuno Generation 34/31 was: 88.3-mph.
The Bottom Line?
Well, according to the baseball batting practice Mizuno bat model experiment data, it looks like the Generation model holds the performance edge when it comes to Ball Exit Speed, almost a 5-mph difference. That’s about 20-feet of extra distance! From how the experiment turned out, I’d save the $200 and buy a Mizuno Generation. Now, this data doesn’t mean EVERY expensive bat will under-perform it’s more economic brethren, it just means you need to tinker and test to find the truth.

Baseball Equipment Training for Hitters: Never Suffer from Paralysis by Analysis Again
This is a shortlist of the thousands of dollars I’ve spent on educating myself about how the human body moves…
I often get asked about baseball equipment, books, and other resources to use, from coaches about hitting.
From hitting aids…to hitting programs…to hitting books.
There’s a potential for exponential growth in this information age, for coaches. There’s no excuse not to succeed nowadays. As Tony Robbins says,
“Where focus goes, energy flows.”
I wanted to share a list of equipment, books, and other resources that have helped in my own baseball training equipment for hitters journey.
I do a ton of research and study to find only the best. The key is, does the information or hitting aid hold up to the modern human sciences?
At the end of this post, I’d like to hear from you. What baseball training equipment for hitters (or for coaches) did I leave out?
By the way, this “guide” has as much to do with softball, as it does for baseball.
Think of this post as the definitive guide to baseball training equipment for hitters…
SCIENCE-BASED TRAINING:
Improve your hitting strategy dramatically by applying human movement principles.
Learn not only how and what to train but also the science behind the methods.
Anatomy Trains, by Thomas Myers – this book changed my hitting world. Probably the best book for understanding the way humans move and how to optimize it.
Dynamic Body Exploring Form, Expanding Function, by Dr. Erik Dalton et al. – a collaborative of distinguished movement author experts. Even if you read a couple of the articles in there, you’ll be farther along than the conventional coach.
The Spinal Engine, by Dr. Serge Gracovetsky – he cuts to the heart of the main engine in the swing. I want to warn you though, the information is jargon thick.
The Golfing Machine, by Homer Kelly – Kelly was an aeronautical engineer for Boeing during the Great Depression. He fell in love with golf and began applying engineering principles to the Golf swing.
Make It Stick, by Peter C. Brown – the science of successful learning. This book changed how I train hitting forever.
Disciple of a Master: How to Hit a Baseball to Your Potential, by Stephen J. Ferroli – written in 1986 as an answer to the Ted Williams book The Making Of A Hitter. Ferroli was a bio-mechanical expert who gave more detail to Williams’s study. It’s an easy book to digest. When I was reading it, it was interesting how eerily similar our approaches were because of science.
The Making Of A Hitter, by Jim Lefebvre – particularly the part when he talks about the swing being a combination of Centripetal & Centrifugal Forces.
Sadaharu Oh: A Zen Way Of Baseball, by Sadaharu Oh & David Falkner – from the Japanese baseball career home-run leader (he hit 868 homers!!).
The Captain: The Journey Of Derek Jeter, by Ian O’Conner – great example of hard work and dedication paying off. Not to mention one of the better human examples of ethics and morals.
Wooden: A Lifetime of Observations and Reflections On and Off the Court, by John Wooden – I actually haven’t read this one yet, but have read through quite a bit of Coach Wooden’s stuff. My college baseball Coach Bob Bennett used a lot of his coaching principles. But I’d be remiss if I didn’t include one of Coach Wooden’s books as a resource for coaches. By the way, this is the best rated on Amazon.com.

Baseball Training for Hitters: Hitting Aids
TheStartingLineupStore.com
In March of 2011, I put together an online store selecting the best 9 hitting aids on the planet. It’s called TheStartingLineupStore.com. I won’t go into all of them here, but I wanted to highlight my top-4 sellers:
Rotex Motion – helping hitters move better, so they can move better.
The Kinetic Arm – protective shoulder and elbow sleeve that reduces compression in the UCL (Ulner Collateral Ligament) and shoulder.
“Goliath” end-loaded heavy wooden bat – get benefit of swinging end loaded heavy bat AND wood, so you’re hitters can get stronger and control the barrel better.
Top-4 essential baseball training equipment for hitters…
Zepp Baseball App (Zepp doesn’t make this anymore, so check out SwingTracker or BlastMotion) – the Zepp device attaches to the knob of the bat, and registers bat speed, ball exit speed, hand speed, swing path, attack angle, etc. to the coordinating app on your phone. It carries a hefty price tag at $150, but for coaches serious about running swing experiments, it’s a MUST!! CLICK HERE for an experiment I did using it.
Coaches Eye App OR HudlTech – slow motion analysis for your phone. Both apps are compatible with both the iphone and android. I have the CoachesEye. Both are free I believe.
Powerchalk – web based motion analysis. You don’t have to download any software to your computer. The free membership comes with: 1) The ability to upload ten separate videos to your own Video Locker, 2) Two-minutes of recording time per analysis, 3) 10-slot video locker, and 4) Upload and share video content.
If you digest the baseball training equipment for hitters book suggestions alone, you’ll put yourself in the top 1% of hitting coaches, instructors, and trainers. As Ralph Waldo Emerson once said:
“The man who grasps principles can successfully select his own methods. The man who tries methods, ignoring principles, is sure to have trouble.”
And don’t just stop there. Read player biographies and auto-biographies of past players like Ted Williams, Babe Ruth, Joe Dimaggio, etc. That being said…

Mike Trout Hitting Golf Ball: Same As Baseball Swing?
What we go over in this Mike Trout hitting golf ball video:
As Physicist, Electrical Engineer, and author of The Spinal Engine, Dr. Serge Gracovetsky says the arms and legs ARE NOT necessary for locomotion, they’re an enhancement. When it comes to spinal movement, hitting is basic locomotion. Fact.
Shifting Foot Pressure
A couple recent posts I’ve done complimenting the above video…
Very few are teaching this. This is at the heart of a stable swing. I see a lot of hitters over-rotating their lower half. Back foot heel moving closer to the the plate versus staying far away. When the hitter shifts pressure to pinky side of front foot, we should see them shift back foot pressure to the big toe side. If instead hitter shifts back foot pressure to outside (over-rotates), then hitter is unstable with low half.
The Big-3 are fundamental to building consistent power in hitters. They’re a combination of using springy fascia and the spinal engine. Responsible for 70-80% of consistent power. Legs contribute only 20-30% to power.

Learn how to increase your hitter’s bat speed, hitting power, and hit the baseball or softball harder every time like Javier Baez in this swing breakdown…
Javier Baez Swing Analysis: Why Inward Turn Of Hips Is Wasted Movement
Hey, what’s going on it’s Joey Myers from the Hitting Performance Lab, and in this Javier Baez swing analysis, we will cover:
Let’s get into the fan graph metrics. As you can see here, look at the six foot, hundred ninety-pound Javier Baez in the swing analysis we’ll be looking at in 2019. You can see his line right here. You can see a .281 batting average, 38 doubles, four triples, 29 homers, and you see a big giant balloon over here, one hundred fifty-six strikeouts and only twenty-eight walks.
Now, if we look at his line when it comes to ground ball, fly ball, line drive percentages, and his fly ball home run ratio and his pull and hard contact numbers, we look at his line drive rate being eighteen point one. You can see his averages over the amount of years he’s been in the Bigs is 19. So, a little bit down from his average.
You can see his ground ball percentage was up quite a bit, fifty point three, which was down in prior years as low as 44 percent and 37.3 percent.
You can see the average line drive rate is 20 percent or so. So as long as they’re around 18 to 22 percent, that tend to be about league average. The ground ball percentage, league average is about 43 percent or around 40 percent. You can see he’s well above average on the ground ball percentage and fly ball percentage typically floats around 37, 38 percent at league average.
So you can see he’s below well below average when it comes to the fly ball percentage homerun to fly ball ratio, the percentage at 24.4, league average is around 9 to 11 percent. So, if he gets the ball in the air or his fly balls, the percentages of his fly balls going out are almost 25 percent.
What’s also interesting to note is if you look over at his soft percentage contact medium and his hard contact percentages, you can see that his medium actually outweighs his hard percentage contact. Some interesting things going on from this Javier Baez swing analysis, might shed a little bit of light on that.
But I thought interesting to note that his hard ball contact percentage at 37.4, you can’t see it on the screen, hard contact percentage. And then you can see as medium here is 44.6.
Over-Rotation of Lower Half During Pre-Loading Phase
All right. Let’s get into the Javier Baez swing analysis, and the breakdown of his mechanics. Let’s give this a little context. This is a two thousand nineteen swing, I think, in May or so. And this pitch looks like a ninety-one mile an hour slider that ends up, as you can see in the K zone in that lower outside quadrant. And he hits this one out to right center a little bit more towards center but right center.
One thing I want you to take a look at is over rotation of the lower half. This is something I think Ted Williams said in The Science of Hitting. And a lot of instructors out there will take this to the extreme. And they think that by turning the pelvis in towards the catcher, so imagine a hitter’s belt buckle turning in to face the catcher. Like there was a flashlight coming out of the belt buckle and that you’re shining the flashlight at the catcher to get the hips some momentum.
Now, I think this is wasted movement when it comes to function of the spinal engine. Not my opinion, but if we look at springy fascia, the spinal engine, what we want is we want to see this front shoulder … we’ll get a chest view here in a second … we want to get this front shoulder to go down in and towards the back hip. And we want this back shoulder to move away from this front hip.
When you move the pelvis in or you move the front hip bone in along with the shoulder, is that now the hip and the shoulder are chasing each other instead of doing the opposite in what we would find in a wringing towel type of scenario, whereas one hand being the shoulder, the other hand being the pelvis.
We’re seeing a lot of these coaches that will say if and when the pitcher shows you his back back pocket, then you show them yours. This is clearly what Javier Baez is doing in this swing analysis. You can see him really showing his back pocket versus this neutral position that he starts off in, really rolls in with that hip.
Now, if we take a look at another hitter, Khris Davis of the A’s, this is the 2018 swing of his. But he actually steps in the bucket a little bit. You’re going to see a little difference to the hip positioning. Khris Davis really doesn’t waste any motion pulling that belt buckle, this flashlight on the belt buckle, trying to shine it in the catcher’s eyes. He actually keeps it in a neutral position and steps out. Into the bucket.
What both of these players do really well, and I think, Khris actually does better than Baez is because of the lower half over rotation in the pre loading phase of the swing before stride touchdown, we see Khris will keep his hips in a neutral position … but will use this neck tension, which we’ll talk about here in a second to counteract. And he’s really good, Khris, at going the other way, where he hits this one. This is a 94 mile an hour fastball somewhat up in the zone. And he hits this to straight away center.
He does very well going to the opposite field, even though he’s stepping out now, I wouldn’t advise young hitters to do that. And we have a stride drill that fixes getting the stride more in line.
Khris makes this work because of the way he uses his spine. Here’s a chest view of Javier Baez swing analysis, it’s a little angled here, but you can see that kind of over rotation pre loading phase of the pelvis, the lower half versus what Khris Davis was doing.
You can see him really coiling up with the lower half, which he really doesn’t have to. And you’re seeing the what I was talking about is taking this front shoulder down and in towards a back hip and we should actually see this front hip move away from the back shoulder.
When you bring that front hip in, you’re chasing the back shoulder instead of moving away from it, which that’s how springy fascia works, how we load the body like a spring or a catapult. And we want to bring that front shoulder down and in which he is doing. But when you turn the pelvis, it’s almost like the corresponding shoulder is chasing the corresponding diagonal hip bone.
Now, if we look at Khris Davis on the same swing, you know, this view’s a little bit more chest view than the angled version we’re getting with Javier Baez. But you can see that that hip stays in neutral and then you’ll see him bring his front shoulder down and in towards the back hip and you’ll see this front hip move away from the back shoulder.
Some people might call this the scap load that is covering this line here, this diagonal line to scap load. But we also that’s a retraction of the back scap. What we should see is a protraction of the front scap or the front shoulder moving down and in. So, we’re going to see the hitter’s numbers when the hitter does that. We should see both moves, not just one. And you’re seeing Khris Davis do this very well because he keeps his pelvis in neutral.
You can see here and just lets his upper half preload and let his lower half just do what it does and let it open as it does to take the rest of the slack out of the spinal engine.
And one more quick thing before we move on from this in this Javier Baez swing analysis … as you can see, as he coils up him in Davis, pretty much end up in the same spot, at landing. Look at where his pelvis is at landing. So, it’s almost like he gets a running start with his pelvis. I don’t think it really relevant because we’re getting the same effect with the bounce effect with Davis as we are with Baez. It’s just I think Baez’s closing himself off more. And I wouldn’t teach this to young hitters.
I wouldn’t over rotate the pelvis or turn the pelvis inward towards the catcher to landing, because at landing, you see he’s in the same position. And as long as he’s getting his neck pressure, which will be transitioning to here, as long as you get into neck pressure, he’ll be wound up top. And then once the lower half starts to open, as he starts to swing that rest of that slack, will get taken out and then everything will go as it’s supposed to.

Now, let’s talk about creating neck pressure. The idea of this is like wringing a towel out except for one hand represents the head, the other hand represents the shoulder. So, the hand’s turn in opposite directions. And what we’re trying to do is it’s not so much about how much of the numbers the hitter shows, although Javier Baez in the swing analysis, you can see you can see everything. If he had a triple digit number, you could see three digits on his back. You can see his back elbow. You can see all the way across the shoulders. If he had a 20-word last name, you could see it from armpit to armpit. You can see pretty much everything, almost his rear oblique. You can see because he’s shown his numbers so much.
Whereas we look at a Khris Davis on this one. Similar, but not quite as turned in because he’s not turning the pelvis in. He doesn’t have to. He can create this Catapult Loading System just by keeping the pelvis in neutral and let the pelvis open when it does. He needs to create that bounce with the lower half, create that neck pressure up top.
You can see that he’s locked in, his head is anchoring a tracking position so he can track the ball and keep vision on the ball. It’s not this idea of what some of these coaches call “false separation”, which when these coaches show on video, what false separation is there over rotating the upper half. Now, we don’t want to over rotate. We can’t lose sight with the back eye. And that’s not Davis here. Maybe he is. He is clearly along with Baez. They are clearly showing their numbers, showing their last name. You can see that is clear as day.
There is a pro attraction of the front scap. There’s a retraction to the back scap. You’re seeing both of those things happen in two different hitters on two different teams. And what both of them do are doing and having common is they are wringing the towel out head and shoulders. The head creates an anchor point. Their shoulders rotate under the chin as far as they can while creating this neck pressure in the T1 (Thoracic section of spine, vertebrae-1) and C7 (Cervical section of spine, vertebrae-7) area.
So there’s like a two, three-inch area that if the hitter does this right, they create that pressure there with the head anchored with the shoulder pulled under as far as it can do. And they’ll feel this pressure up until the turn and they can go from there. That’s taking slack out of this system early. If this doesn’t happen, there is going to be compensation somehow in that there may be a front shoulder pulling out early. There might be a barrel that’s dumping deep and early into the zone to try and hurry up, get the barrel to the ball.
But above all, hitters must, even hitters as young as eight, nine, 10 years old need to feel that pressure if there is going to be power the minute that pressure is taken off between the head and the shoulders, that is when we’ll be letting air out of the balloon.
The reason that I’ve moved to more of a neck pressure, creating neck pressure versus showing numbers is that every hitter is going to be different when it comes to their mobility in their neck and their thoracic spine or their shoulders being able to turn the head this much as much as Baez or Davis. Davis isn’t quite as much there. Maybe it’s just with Baez because he’s inward rotating his lower half. It’s allowing him to turn more.
I think that again, hinders it can take our vision and tracking off the ball if we do this with younger hitters, what Baez is doing. So, I would recommend more of what Davis is doing, albeit without the stepping out part of it. But we want to create the neck pressure. That is the rule. That is the principle, the movement principle, the wringing towel principle to the Catapult Loading Systemin spinal engine, springy fascia.
It is not so much to show both numbers. The numbers will probably show, but it will depend on the hitter’s mobility in their neck. So, every hitter might be different.
Barrel Tilt
One last thing in this Javier Baez swing analysis is the barrel tilt. There are some coaches out there that like this barrel till where you can see where Baez tilts the barrel towards the opposing batter’s box or kind of off towards first base and to get the barrel momentum going into the swing.
Now, this might be something that Baez needs to do because he is rotating that lower half inward towards the catcher. And to get some barrel momentum is going to help him to get around, especially on pitches in pitches up in the zone.
I don’t teach this per se. I don’t think it’s a bad or good thing it can be a bad thing. If they tilt too much and I think Baez in the past has tilted too much and it’s got him in trouble, it causes more of an uppercut type of swing. I’ve had hitters that do this and they hit the ball in the air more often than the hitter that doesn’t tilt the barrel this much.
We’ve seen Donaldson from I think it was 2013 to 14. He was tilting too much and we saw his fly ball percentage go up and his batting average go down. So, I would not really mess with this too much as long as we are creating that wringing towel effect between the head and the shoulders, creating the neck pressure.
And we are what I like to tell my hitters is to act like there’s a skewer going through their hip bones that is keeping him on a straight line, keeping hip bones on a straight line towards the catcher. And they just slide along that skewer until the front foot hits the ground and they can turn out of it, but they can’t turn into the skewer up until landing … has to stay in a neutral position and they manipulate the neck pressure at the top to create the tension that we need to be able to instantaneously swing the bat and increase our ball exit speeds.
The barrel tilt is just not something that I would teach my hitters. I would let my hitters do it. But if it’s affecting their fly ball, line drive, ground-ball ratios and we would definitely change it. Now, I hope you like this Javier Baez swing analysis. Make sure that you’re swinging smarter by moving better.

Mookie Betts Swing Analysis: Build Massive Power For Small Sluggers Like Mookie Betts & Trea Turner…
What we’ll be contrasting in this Mookie Betts swing analysis compared with Trea Turner:
Few out there think power comes from the snapping of the back hip and barrel. These people are only one-third of the way there. The pelvis (including hip), spine, and shoulders as a complete unit is where to find consistent power.
There are three pieces of our spine:
Cervical (neck)
Thoracic (shoulders and middle back), and
Lumbar (lower back).
Imagine each section as a hand. Now imagine three hands wringing a towel out. The top (Cervical) and the bottom (Lumbar) are wringing in the same direction, while the middle (Thoracic) is wringing in the opposite direction of its “bookends”. Mookie Betts does this just as well as anybody.
When it comes to barrel path, these same “snapper” hitting instructors promote a one path fits all barrel path. And they claim teaching a high level pattern. This is the exact opposite of what a higher level pattern is. The best hitters’ barrel enters the hitting zone at different points depending on pitch depth. You don’t see Mookie Betts knocking off the “real” catcher’s glove when hitting 97-mph inside. If he did, he’d be picking up his thumbs. Or he’d have to bend his front elbow so significantly that it would drop his average ball exit speeds by 20-mph, which equals at least 80-feet of batted ball distance.
Shorten the lever, you shorten power amplification. The “snappy” pattern has its consequences.

Does a Modified Bat Handle Increase Bat & Ball Exit Speeds?
ProXR bat knobs are similar to an axe handle, but are more rounded…
In this baseball hitting drills for contact bat knob experiment using the Zepp (Labs) Baseball app & Bushnell radar gun, I wanted to use the Scientific Method to analyze what would happen to Bat and Ball Exit Speeds when using the same model and sized wood bat, but the only difference being that one bat has a regular knob, and the other a ProXR knob.
Background Research
A Washington University study found there was a 20% to 25% reduction in compression forces in the hands when using a ProXR technology.
My fascination with this all started when Grady Phelan, the Founder and President at ProXR, LLC, wrote this LinkedIn post titled, “Baseball’s Broken Hamate Plague“.
After I reached out, Grady was open to the idea of doing a Zepp and Ball Exit Speed baseball hitting drills for contact experiment.
Grady shared the following research about his ProXR technology over email…
“One of the experiments we did early on with ProXR, as part of our due diligence before we went to market, was to measure the compression forces in the hands during a swing. I was fortunate enough to be able to work with some researchers at Washington University School of Medicine, Bio-Mechanics lab here in St. Louis. We connected a conventional bat and a ProXR bat to digital pressure sensors and had a batter take some swings. We were able to dial into the area of the hypothenar (the heal of your hand below your pinky) and compare the difference in compression.
What we found was a 20% to 25% reduction in compression forces when using a ProXR technology. The peak compression happens immediately AFTER intended contact when the hands roll over the central axis of the bat and the knob. The smaller peaks in between the high compression peaks are from the batter getting the bat back into the load position and we took out the time in between swings to condense the chart.”
SCIENCE-BASED TRAINING:
Improve your hitting strategy dramatically by applying human movement principles.
Learn not only how and what to train but also the science behind the methods.
“Pedroia is actually using something called an axe that is being put on a Victus bat. There is some minor confusion in the market given the axe’s similar look with ProXR.
Here’s the top-line difference between ProXR and the Baden product: if you’ve ever swung an actual axe (chopping wood), which the Baden product is based on, you know that the swing path is linear, meaning it drives the hands to the point of contact AND (this is probably the most important point) the swing ends at contact. This is critical. The oval shape of an axe handle and the general configuration of the axe handle evolved over thousands of years specifically to drive the axe head to the point of contact (this also applies to swords, hammers and other linear-path swing implements). The oval shape locks the hands into alignment with the swing path and PREVENTS the hands from deviating from that swing path. In sharp contrast, you know a baseball swing is rotational – meaning the bat must fully rotate around the batters body and the hands MUST roll over the central axis of the bat to compete the swing. This gives hitter the ability to both, make adjustments during the swing and complete the rotational swing path. Putting an oval axe handle on a baseball bat is counter-intuitive to the requirements of a rotational baseball swing. Imagine trying to adjust your swing on a breaking ball or change-up when the shape of the handle is resisting those adjustments.
In contrast, ProXR was designed from the ground-up specifically for a rotational baseball bat swing. It reduces compression in the hands and gives batters improved performance. Additionally, we tested our designs before we went to market and continue to do ongoing research and testing. As a side note, ProXR was accepted into the National Baseball Hall of Fame in 2011 because it is the first angled knob bat ever used in regular season games.”
Hypothesis
Based on the ProXR technology research, I was convinced the bat would alleviate compression forces in the hands, particularly the hitter’s bottom hand. However, my biggest question was, are we sacrificing performance to be safer? I think the ProXR technology, although safer, will sacrifice some performance.
The reason I labeled this a “baseball hitting drills for contact” experiment will become clear in the “Notes” section of the post, so stay tuned…
Baseball Hitting Drills for Contact: ProXR Bat Knob Experiment
33-inch wood bat model 243A with regular knob, and
33-inch wood bat model 243A with ProXR knob
Setup:
All swings for the baseball hitting drills for contact experiment were taken off the tee.
I used two yellow dimple ball markers to make my stance setup consistent…one was placed inside my back foot, close to the plate. The other was placed one bat’s length plus two baseballs in front of the back marker.
CLICK HERE for the Google Drive excel document with all the Ball Exit Speed (BES) readings and calculations.
We deleted radar gun mis-reads that registered below 30-mph on the gun.
Therefore, we deleted 3 mis-reads from the ProXR bat knob data, and averaged all ProXR BES readings to 97 swings.
Also, we deleted 2 mis-reads from the regular bat knob data, and averaged all regular bat knob BES readings to 98 swings.
The two tests in the baseball hitting drills for contact experiment were counter-balanced. Which consisted of eight blocks of 25-swings done in the following order ABBA BAAB. Swinging the “ProXR Knob” were letter ‘A’, and
“Regular Knob” were 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.

A slight baseball hitting drills for contact advantage goes to the ProXR Knob…
Data Analysis & Conclusion
ZEPP READINGS:
Avg. Bat Speed at Impact increased by 1-mph using the ProXR knob bat,
Avg. Max Hand Speed didn’t change,
Avg. Time to Impact decreased by 0.004 swinging the ProXR knob bat,
Avg. Bat Vertical Angle at Impact decreased by 2 degrees using the ProXR knob bat, and
Avg. Attack Angle decreased by 4 degrees using the ProXR knob bat.
BUSHNELL BALL EXIT SPEED READINGS (CLICK HERE for Google Excel Doc):
Avg. Ball Exit Speed decreased by 0.4-mph using the ProXR bat knob, and
Top out Ball Exit Speed was 93-mph using both the ProXR and conventional bat knob.
Notes
In ProXR founder Grady Phelan’s initial testings of professional players, some of the players recorded a 3 to 10-mph bat speed increase using his ProXR knob. Now, I have a theory as to why my numbers were much smaller…
For all 208 swings I was playing with two baseball hitting drills for contact mechanical elements in my swing: 1) squeezing the bottom three fingers of my top hand only, from the moment I started my swing (picked up my front foot), through impact. And 2) having more of a “hunched over” posture at the start of the swing. I did this for all swings, so as not to “muddy up” the experiment.
The finger pressure may have neutralized the affect of the ProXR knob, since most of the “shock” at impact was taken by my top hand. Whereas a normal hitter not using top hand finger pressure would absorb the shock in the hamate bone, in their bottom hand, using the regular knob bat.
Playing around with both baseball hitting drills for contact elements of #2 above, I compared the Ball Exit Speed numbers from my previous experiment looking at the difference between the Mizuno Generation ($200 bat) to the Mizuno MaxCor ($400) bat where I wasn’t using the two mechanical changes. Interestingly, my average Ball Exit Speed with the $400 alloy MaxCore was 83.5-mph and top out exit speed was 90-mph. With the wood bats, my average Ball Exit Speed was 89 to 90-mph, and my top out exit speed was 93-mph. That’s a 6.5-mph jump in average & 3-mph boost in top out exit speed using a wood bat over a non-wood!! That’s 26 more feet on average, and 12 more feet in top out distance added using finger pressure and the “hunch”!
By using the two principles in #2 above, I was able to hit the “high-note” more consistently. I also had less “mis-reads” in this experiment, using the radar gun (5 total out of 208 swings), versus the Mizuno bat model experiment (18 total out of 200 swings). This is why I labeled this experiment “baseball hitting drills for contact”.
After about 50 swings in the the ProXR bat knob baseball hitting drills for contact experiment, I could tell you what my Ball Exit Speed readings were going to be after each cut, +/-1 mile per hour. Crazy!
The Bottom Line?
Well, according to the baseball hitting drills for contact ProXR bat knob experiment data, it looks like the ProXR knob holds a slight edge in performance versus the convention knob. Coupled with the fact that the ProXR knob reduces compression forces on the hands by 20 to 25% has me convinced that ProXR bat knob technology is a can’t lose tool for a hitter’s toolbox.
