THREAD w/ breakdown below:

The voting has ended!
- nearly 5,000 votes
- The most voted for was Blue at 46% and he actually threw the slowest: 90.9 mph 🤔
- Green was the winner at 95 mph!
- pitching mechanics are hard

Some thoughts and a breakdown of Green's mechanics below ⬇️

There were over 200+ comments on the original poll with tons of ideas about pitching mechanics and why you thought your vote was the hardest thrower. As everyone hopefully learned, it's a lot harder than it looks. Much of pitching and baseball coaching that exists is a "guess"

Why would you leave your development as a player to a guess? That's the power of biomechanics integrated w/ the assessment. It eliminates that guessing game. We quantify and measure everything. Every movement, metric, frame, etc. Just raw objective data and numbers.

Nothing slips through the cracks. We see everything in the lab. Even with reconstructed 3D skeleton visuals on display, it wasn't easy. People still made incorrect guesses and assumptions about athletes "hip/shoulder separation" and plenty of other metrics:

So here's the data:

GREEN:

- Height- 6'7
- Weight- 225 lbs
- (this helps)
- this pitch was 95 mph. Has hit triple digits before.

Early arm action metrics at foot plant:

- elbow flexion: 109 degs
- should abduction: 94 degs
- huge scap load, shoulder horizontal abduction: 93 degs

general notes: really clean and efficient, sets up the rest of the arm action nicely to deploy appropriately.

Arm action and Torso metrics

- lateral trunk tilt: only 7 degs
- trunk holding counter-rotation until the last moment

Does a really good job at holding an efficient torso position. If the trunk were to rotate any earlier, it would pull the arm out of scap load too soon.

lower body kinematic positions:

- pelvis opens on time.
- Leg plants and braces almost immediately
- Lead leg block combined with position of the hips at plant facilitates faster pelvis rotation and transfers up the chain

Rotation Velocities: All above average

- nothing really to note here besides that. He achieves great positions throughout the throw and also rotates them well above average.
- The pelvis rotation is especially above average = 946 deg/sec 🔥🔥

Kinematic Sequencing: Perfect

Momentum is transferred segment to segment with enough of a delay/separation between each:
Pelvis(purple) ➡️ Torso(red) ➡️ Elbow ext(green) ➡️ Internal Rotation (blue)

NOTE: peak pelvis rotation happens AFTER foot plant (second vertical line) 🔥

"Put all of that together and you get a 95 mph fastball."

Or maybe you don't? I can't say that if everyone just hits those metrics, they'll throw 95 mph, because the equation is much more complex. These are just pieces to the puzzle that make up your mechanics

That's why the assessment at @drivelinebases is unmatched.. Nothing is looked at in a vacuum. Everything is collected, integrated, and analyzed together to understand where you are right now, and then individualize everything going forward. No guessing.
