I agree with the esteemed Mr Fullmer’s assessment but I’ll add some pics
1. The glove foot has landed. The baseball is behind the pitchers head not remotely directed toward home plate yet. I think it’s well past time for a dad to ask Mr Pourciau how he thinks legs contribute to this velocity.
As with Lon I prefer velocity, so the index and middle finger should be contiguous.
2. Brent’s cutter is my Torque fastball. They both move to the glove side of home plate. Once again I prefer that the middle and index fingers are contiguous. I prefer dramatic movement so I disagree with Brent’s seam orientation.
3. As we see here, the Slider is a difficult pitch to master. I think pitchers can get through high school without it. We see the upper arm and forearm form a straight line. All a caring parent has to do is throw their arm out to the side and turn their thumb up as hard as they can. On second thought don’t do that. Save the pain for your sons.
4. Splitter - this is a very effective pitch. I don’t want to waste everyone’s time with a tutorial on seven Interossei muscles but this is a dangerous pitch. At a minimum a pitcher should have long fingers.
Another great video from Dr Pourciau. Thanks much
Steal these 4 grips. ⚾🔥
1️⃣ 4-Seam
2️⃣ Cutter
3️⃣ Slider
4️⃣ Splitter
See the grip. Watch it move. Then watch it hit the glove.

“Why is your arm hurting? It could be early trunk rotation.”
I have to believe by arm, Brent is referring to the pitching shoulder.
To maximize velocity, albeit without injury, baseball pitchers have to ‘lock’ their pitching upper arm to their torso. I don’t talk about this much, so gurus have no idea how to do it.
I often say ….When pitchers start wrong….it ends badly. When I write this or you can word search the phrase, I usually show the pitcher in his wind-up (Transition phase). I usually show the pitcher’s elbow beyond the imaginary straight line toward 2nd base. The resultant arc I describe is deadly to the front and back of the pitching shoulder.
A correct windup seems like something that would be easy to accomplish. It is actually very difficult.
As for Dr Pourciau’s contention that early torso rotation injures arms, I challenge someone, anyone to post video of a pitcher who rotate his shoulders before his glove foot lands. Usually pitchers rotate their hips early. But I’ll keep an open mind
Why is your arm hurting? It could be early trunk rotation. 👇
A new 2026 study tracked 339 pro pitchers with 3D motion capture. The ones whose trunk turned BEFORE the front foot landed:
⚾ threw no harder
💥 put about 8% of their bodyweight more force on the elbow, and nearly 10% more on the shoulder
Every pitch. All season.
The 2-second check: film from the side and pause when the front foot lands.
✅ Glove up, chest still closed = on time
❌ Glove down, chest facing the target = early
That's why I invented the Trunk Excelerator. It locks the arm with the shoulders so early rotation can't hide, and you learn to hold the trunk and let the hips lead.

Until dads say enough is enough, the carnage and heartbreak will continue

“↓ If your elbow hurts after you throw hard, read this.
Your elbow is the last link in the chain.”
If Brent is talking about the kinetic chain the forearm, wrist, hand and finger joints follow the elbow joint action in the kinetic chain for pitchers. The order of joint action can’t change.
———
“The forearm muscles that sit over your UCL help resist the valgus stress of every pitch, like a seatbelt for the ligament.”
Valgus stress has nothing to do with rupturing the Ulnar Collateral Ligament. Not understanding muscle action is at the root cause of all these unnecessary pitching injuries. ASMI refuses to understand muscle action. It’s made them a lot of cents.
Five powerful pitching muscles attach to the Medial Epicondyle on the inner (baby finger) side of the elbow. These muscle arise above and attach below the elbow. When these muscles contract mioanglosly they move the forearm tightly against the upper arm.
If pitchers do this, the Ulnar Collateral Ligament received zero stress. Valgus stress
Most everyone has heard Brent and every other surgeon-loving guru talk about Max External Rotation or Layback. When pitchers go into MER the muscles on the outside of their elbow are contracting. This means the muscles on the insides of the elbow, the five Medial Epicondyle muscles, can’t contract. So Brent et al are teaching pitchers how to rupture their Ulnar Collateral Ligament
This is not an easy kinesiological concept to understand but it is inexcusable that guys with letters after their name refuse to acknowledge Reciprocal Inhibition . All parents have to do is ask them about this.
What parents refuse to understand is their sons can be as strong as King Kong and if they go into Maximum External Rotation, there is no muscle action that protects the Ulnar Collateral Ligament.
If you do it my way, you’ll throw with more velocity.
I prefer velocity over injury.
↓ If your elbow hurts after you throw hard, read this.
Your elbow is the last link in the chain. The forearm muscles that sit over your UCL help resist the valgus stress of every pitch, like a seatbelt for the ligament.
The catch: they fatigue. In collegiate pitchers, that muscular "seatbelt" strength dropped about 10% after 7 innings while the stress on the elbow stayed the same, so the ligament carries more of the load late in outings.
After 100 pitches, high school pitchers needed about 24 hours to fully recover that stability.
To be straight with you, the research isn't settled on how much forearm strength protects the ligament itself. What it does build is a forearm that holds up longer late in an outing.
So yes, do these:
1️⃣ Add them to your pre-throw warm-up
2️⃣ 2 x 15 reps each
3️⃣ Slow and controlled. Not fast.
But I wish it was this simple. Arm care alone isn't enough to keep you healthy.
How you throw decides how much load your elbow takes. In adult pitchers, rotating the trunk too early was linked to higher elbow valgus load. No band routine fixes timing.
Submit your video to MechanicsDNA Mini at topvelocity.org and we'll find the real problem.
If something is already sore, that calls for an assessment from a medical professional, not a warm-up.
