Amy Gill and Andrew Marden from KSEE24, a local sports news station here in Fresno, CA, put this video together of an HPL Batted Ball Distance Challenge held about a month ago.
We worked primarily on testing “showing the numbers“, and the results were interesting…
Twelve total hitters, ranging in ages from 8-17 years old. Nine of them had been exposed to the HPL system. Two of them had not, and one had minimal exposure.
The familiar ones (control group) gained or lost between -1 to +1-mph of Ball Exit Speed, while the three “newbies” gained between 3 and 10-mph of Ball Exit Speed in one 30-minute session. That’s between 15 to 50-feet of added batted ball distance!!
The Definitive Guide To Measuring, Tracking, & Boosting Ball Exit Speed
On April 23rd, 2015…
The Toronto Blue Jays’ 3rd baseman, Josh Donaldson, hit a two-run homer to left off Chris Tillman that was clocked at 120.5-mph!
And as of August 18th, according to ESPN’s HitTrackerOnline.com, was the highest Ball Exit Speed home-run in 2015.
CLICK HERE to see the 120.5-mph Josh Donaldson two-run dinger.
By the way, this topped Giancarlo Stanton’s highest Ball Exit Speed homer, in the same year, by 3.2-mph (117.3-mph).
How does Josh Donaldson do it?
I mean, come on!
Giancarlo Stanton, also referred to as “Bigfoot”, stands at a gargantuan 6-foot, 6-inches tall, 240-pounds. And from what I hear, has about 3-4% bodyfat.
On the other hand, Josh Donaldson stands in at mere 6-foot, 220-pounds.
Talk about David & Goliath!
But what little realize about David was that he was an expert marksman from long range. So he never had to go toe-to-toe with Goliath.
David had a better strategy. And so do small sluggers like Josh Donaldson.
In this post, we’ll be talking about Ball Exit Speed (BES), also known as Speed Off the Bat (SOB), or simply Exit Speed. We’ll learn:
- What affects Ball Exit Speeds?
- What is the Desirable Minimum Effective Dosage (MED) for Ball Exit Speed? And
- How-to increase Ball Exit Speed…
What Affects Ball Exit Speeds?
“What gets measured gets managed.” – Peter Drucker
Recently, I’ve been using a Bushnell Radar Gun to measure the Ball Exit Speeds of my hitters, off the tee, before and after each session.
It’s not radar gun accuracy we’re looking for here, but an apples to apples comparison. Here’s what we’re comparing, using the radar gun, before and after each hitting session:
- Did the hitter beat a personal record (PR), and/or
- How consistent and stable their Ball Exit Speed readings are, or whether they’re jumping all over the place.
Unlike bat speed, there are many things that can affect the speed of the ball coming off the bat:
- Bat Composition (BESR rating) – Wood v. non-wood. End loaded v. more balanced weight. Bat size and weight.
- Ball Composition (COR rating) – Plastic balls v. rawhide. Corked core v. rubber. Higher v. lower seams.
- Hitter’s Body Mass – Dropping a 50-pound plate on your foot will turn out worse for you, versus a 10-pound one.
- Ball Spin Rate – Backspin and topspin, in addition to the coveted knuckleball will all affect BES differently.
- Effective Mechanics – the better a hitter is at effectively using human movement rules that are validated by science, the better energy transfer from body to barrel to ball.
- Pitching Velocity – From what I’ve heard and seen, pitch speed can add between 10-20-mph to Ball Exit Speeds, say from off the tee.
- Fatigue – sleep, over-training, nutrition, and supplementation. CLICK HERE for Zach Calhoon’s recovery shake mix.
- Warm Up Factor – I noticed in my latest Zepp swing experiment, that I didn’t consistently hit 90+mph Ball Exit Speed, off the tee, until I reached about the 75 swing mark.
- Learning New Hitting Mechanics – I’ve noticed with my hitters that when we introduce a brand new hitting movement into their swing, their Ball Exit Speeds drop between one to four-mph. But if it’s something we’ve covered before, then they may actually increase by one to four-mph.
- Timing – If a hitter is too late, and doesn’t allow his or her bat speed to mature, then Ball Exit Speeds will be lower. If a hitter is too early, and their bat speed has begun to decelerate, then Ball Exit Speeds will also go down.
- Environment – Humidity dampens Ball Exit Speeds (pun intended). So does a head wind, duh. On the other hand, hitting in dry hotter climates OR in Denver, Colorado, Ball Exit Speeds will increase because the air is less dense.
- Hitting the Sweet Spot – Hitting the ball on the end of the bat, or closer to the hands will decrease Ball Exit Speed, while consistently hitting the sweet spot will boost it.
- Bat Speed at Impact – Most of the time Ball Exit Speeds will be higher than Bat Speed at Impact. With my Zepp swing experiments off the tee, it looks to be about a 6-mph difference.
- Strength and conditioning – this can help but shouldn’t be the highest priority. This should be the cherry on top.
- Mobility and stability – if you move better, then you perform better. Simple as that. This MUST be a high priority not just to increase BES, but to minimize an athlete’s risk for injury.
What is the Desirable Minimum Effective Dosage (MED) for Ball Exit Speed?
“The smallest dose that will produce the desired outcome.” – Tim Ferriss on MED, 3-time NY Times Bestselling Author
According to this Wall Street Journal article titled, Yankees Dive Into the Numbers to Find Winning Patterns,
“Computers can track a ball’s exit velocity, launch angle, hang time and spin rate, 100 mph, the
speed necessary for most home runs; 75 mph, commonly the break-even pace for a ground ball to skip through the infield for a hit; and four seconds, the inflection point for fly ball hang-time, with any remaining in the air that long before getting caught.”
You may be wondering, what is the launch angle for a typical home-run? According to the following Sports Science video, about 20-degrees:
According to a Beyond the Boxscore article titled, Do Hard Hit Ground-balls Produce More Errors?, that there is no significant increase in errors, at the Major League level, until Ball Exit Speeds reach and go beyond 95-mph.
This NY Times article titled, New Way To Judge Hitters? It’s Rocket Science – Sort Of, reports about Ball Exit Speed that:
- The threshold for hitting a homerun is 95-mph,
- Ball Exit Speed is being used to evaluate upcoming professionals, and can decide who starts,
- Managers can use Ball Exit Speeds to see if there’s a drop off in a hitter’s Ball Exit Speed, which may reveal the player is hurt or needs to adjust their mechanics, and
- Teams can shift their infielders back with hitters clocking higher Ball Exit Speeds.
And lastly, an article from eFastball.com titled, Bat Speed, Batted Ball Speed (Exit Speed) in MPH by Age Group, had this to say:
“MLB average exit speed is 103 mph, bat speed ranges roughly from 70-85 mph. 1 mph of additional exit speed makes the ball go 5 more feet. This would be roughly 4 feet for 1-mph bat speed – which is less than the 7-8 feet we have heard from other studies.”
Based on the information above, ideally the MED Ball Exit Speed, for the average Little Leaguer, would be 40-mph BES (40-mph BES X 5-feet = 200-feet of distance). I want my Little Leaguers to get to 50-mph BES, for the fields that have 220-foot fences. And of course launch angle is a huge factor in this.
And on the big field, it looks like 95-mph Ball Exit Speed is the MED because that means the hitter has the ability to hit the ball 475-feet (95-mph BES X 5-feet of distance). Furthermore, the fact that Beyond the Boxscore’s observations about errors not increasing until Ball Exit Speeds reach 95-mph.
How-to Increase Ball Exit Speed
“Whenever you find yourself on the side of the majority, it is time to pause and reflect.” – Mark Twain
So, what advantage does a small slugger like Josh Donaldson have over Giancarlo “Bigfoot” Stanton?
Here’s the secret to boosting Ball Exit Speeds…
Tinker and Test.
Remember, Peter Drucker’s quote above?
“What gets measured gets managed.”
Here’s what to do to ensure a healthy increase in Ball Exit Speeds:
- Get yourself a Bushnell Radar Gun and/or a Zepp baseball app,
- CLICK HERE to read the definitive guide to running swing experiments,
- Choose an HPL “Topic” in the navigation bar above, or search for one in the upper right hand corner of the website, and start testing.
- Stop analyzing big hitters. Instead look at the small sluggers, and see what they’re doing to compete, such as: Cano, McCutchen, Donaldson, Bautista, Vogt, Beltre, Braun, Pedroia (averages 44 doubles and 15 homers a season), Victor Martinez, Edwin Encarnacion, David Wright, Hank Aaron, Sadaharu Oh, and Mickey Mantle.
