The Relation Between Exit Velocity and Throwing Velocity

January 3, 2022

For all the years we have been tracking
bat speeds, exit velocity, and throwing velocity
we discovered something many years ago
that proved very interesting to us.

Right around 2008, this was becoming
more obvious as we starting objectively
measuring more athletes.

It was becoming a common thing for a player
to report hitting exit velocity and throwing velocity
to nearly the exact same number.

We would track his crow hop from the field
at 80mph.   It would end up his high exit velocity
would likely be 80mph.

Through years of testing we were finding out
over 70% of the players we were testing and training
we throwing and hitting within 3mph of the two numbers.

Years ago one of our 100mph throwing athletes decided
to pick up a bat even though he had not hit at all in at least
3 or 4 years.

He began swinging on our swing speed radar.   Amazingly
within a few minutes he was reaching speeds of 101 and eventually
102mph. He did this despite not being a college hitter and not even practicing hitting.

Ironically his high throwing velocity
with a crow hop was 102mph.

Another college pitcher as noted above showed
he could generate exit velocity over 100mph which
also matched his throwing velocity on a crow hop type throw.

What does this mean to us? 

It starts with the obvious.  Hitting and throwing a baseball
are a lot more a like than most people think.

Throwing and hitting is a rotational movement.  Rotation is power.
When you improve your rotational power, you are not only effecting
your exit velocity you also may be impacting your throwing power.

This also makes you want to re-think your approach to strength
training and how much does it actually relate to both throwing
and hitting a baseball.

Strength does not equal improved performances in some cases.
Strength simply means your stronger, but no more powerful when
it comes to throwing a baseball or possibly hitting a baseball.

Throwing and hitting requires the ability to take your strength
and move it in a specific manner.  Rotation is a big part of that
force that is created.

This is one of the reasons why we have seen some players
go off on their own personal strength training program and come
back with less throwing velocity than ever.

When players start climbing towards 100mph it get’s challenging!

I have found the most challenging time for most is when exit
velocity starts climbing closer to 100mph.   It becomes a lot more
challenging to throw it as fast as we hit the ball.

Interesting enough though, almost everyone of our 100mph hitters has been able to throw a baseball over 90mph, so they do close the gap even when speeds
get this high.

All 3 of our 100mph throwers, showed they could generate exit velocity
or bat speed of 100mph.

For a small percentage, exit velocity will fall behind throwing velocity.
For most, the exit velocity is more likely to come out ahead.

Why?   Arm health is part of the equation.   The body will do what
it takes to protect itself first and foremost.   The brain knows too well
sometimes that pushing more is a bad thing.   The arm health factor
plays a role in limitation of throwing velocity in which most hitters don’t
worry about the health factor.

What happens when we start seeing
larger gaps between the speeds?

This could be a RED FLAG showing us a disconnection in either hitting or throwing.
Typically we like to see the two numbers fairly close together.

If we see someone hitting a baseball 80mph, but the exit velocity is say
71mph we know the hitter has a higher ceiling.   We know he might have hidden exit velocity in him right now.  We have to draw it out of him.

This also works the other way around.   If we see someone with 80mph exit velocity and throwing velocity around 71mph we know more is likely in the tank and something is holding them back.

Things to consider….

A corrupted movement pattern on hitting or throwing

A lack of reps or simply reps with the right goal or training intent

The hitter might hit lefty and throw rightly or vice versa.

Arm Health could be playing a factor

These numbers hold true best when the hitters are using
a regulation bat such as a wood bat or even a -3 BBCore.

At times with younger and much more fully developed players,
we will see bat speeds jump to an incredible amount such as
being over 80mph.   This is partially influenced by using a -10, or -8
bat by a very strong youth player.

The throwing velocity will have a hard time catching up
to these speeds simply because the bat is so light compared
to the strength of the young man child athlete.

Typically when that player starts using a wood or -3, the numbers
come back closer together.

If nothing else, this is a good to know
concept at very least and provides another
way to evaluate the player.

This gives us a good idea of where he could
be even if he is not there right now.

Our Total Baseball Power Chart we created years ago challenges
our hitters to move up the player development chain but increases
of both exit velocity and throwing velocity.

We have had 3 players become 200mph athletes by combining
the exit velocity and throwing speeds together.   It provides as
guidance of power training and motivation as players develop
through our system.

Throwing speed and exit speed combined equals
Total Baseball Power.  TBP.
