#1 Youth Baseball Swing Fix To Deflating Bat Speed
Awhile back I posted the following to my Hitting Performance Lab Facebook fan-page (CLICK HERE if you haven’t “Liked” my fan-page yet…new content daily):
This video blog post will target one of the worst youth baseball swing offenders to deflating bat speed…bat drag. In this article, we’re going over:
- What is Bat Drag?
- The science of Bat Drag (to hitting an unknown moving pitch), and
- One way to fix Bat Drag.
What is Bat Drag?
This is when the front arm “bars out” before the Final Turn. Also known as “Casting.” And it’s an oftentimes frustrating youth baseball hitting fix.
I received an email awhile back from James Brown (NOT the singer), that said:
…”I watched a video that perry husband had at the hitting hot stove at the abca in Dallas that showed analysis of the Homerun derby, and the furthest home runs by each individual competitor happened when their lead arm was extended early. I think swing mass and leverage has a lot to power to the ball… Think about having your hand slammed in a door. Would you want a door with a short distance from hinge to knob, or a long distance? Short would close faster, but do less damage. Long will impart more force at a slower speed.”
James Brown’s email response was after I produced this youth baseball Shin-Soo Choo: Can Front Arm KILL Bat Speed? video post.
Here’s how I responded…
The Science of Bat Drag (to hitting an unknown moving pitch)
…”I see what you’re saying and agree…to hit the ball the farthest, a straight front arm would be ideal. Look at golfers for instance. But here’s the problem…a hitter in a game doesn’t know with 100% certainty: pitch location, speed, and pitch type.
So a hitter needs to turn quicker for the first half of the Final Turn, to get the barrel on the plane of the pitch as soon as possible. Then extend on the pitch plane, depending on pitch location and speed.”
In the home run derby, hitters know the pitch speed, type – and for the most part – location.
I agree with Perry Husband in that hitters should make it a goal to get to impact with a long front arm.
However, I don’t agree in getting a hitter to bar that front arm out early on, pre-turn.
It’s a simple Conservation of Angular Momentum issue. CLICK HERE for a short 2-minute Circus Physics video from PBS on this movement Principle.
An ice skater speeds up by tucking her arms in towards her rotating middle. She slows down by extending her arms away from her rotating middle.
What’s going on here?
Rotating speed goes up when the rotation is tighter (bending the arms), but inertial mass decreases. Inversely related, when the arms go out, her inertial mass increases, but her rotating speed decreases. This is how Angular Momentum is conserved.
So, unless like Perry teaches, Pitch Recognition and Strategic hitting game plans against specific pitchers is supplemented, I don’t see the logic in teaching hitters to early arm bar, pre-turn.
Because barring the front arm out early will slow rotation down (think arm extended ice skater), and on higher perceived velocities to the hitter, high or inside the strike-zone, why would we want our hitters to turn slower at the beginning of the turn?
The bottom line? Youth baseball (or softball) swing game mechanics are slightly different than in batting practice. “Five-o-clock” hitters typically aren’t very effective in games. And let me tell you, all my pitching friends LOVE pitching to early arm bar hitters because they have a weakness to exploit. Just like hitters that swing down on the ball and extreme upper cutters do.
One Way to Fix Bat Drag
Typically, I have my youth baseball hitters practice the Catapult Loading System when we have an arm barring issue. The finer points before a hitter lands in the Fight Position are:
- Showing pitcher your numbers,
- Hiding hands from pitcher, and
- Slight downhill shoulder angle.
Another piece I’ve just added to the puzzle comes from Homer Kelly in his book The Golfing Machine. The following quote may shed additional light on “educating the hands” to combat arm barring…
“Power Accumulator #1 (for right handed golfer) – is the bent right arm. 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 restrains 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.”
You see, the problem with bat drag at the youth baseball level isn’t the move itself, but how the compensation is triggered. What’s happening before the front arm bars out? Is the hitter properly activating the springy fascia within the torso?

I’ve spent 11+ years in the corrective fitness industry, and have too many alphabet-soup certifications to bore you with.I also played four years of Division One baseball at Fresno State from 2000-2003.
It’s NOT how you study, but what you study that counts.I apply human movement principles (or rules), validated by science, to hitting a baseball and softball.
