THREAD: Biomechanics breakdown for YELLOW

received 12% of the votes, and actually ended up throwing 92.4 mph, the second hardest of the 4.

what some voters said:

"more explosive lower body"
"quick arm path"
"opens hips last"
"stays closed longest"
"greatest impulse on ball"

Here's the breakdown on Yellow. First, here's a few angles of his mechanics

We'll start with the upper body kinematic positions:

Arm action notes:
- Elbow flexion stays clean and compact
- abduction is a little high at foot plant (>100 degs). Oftentimes, this limits scap load, but in Yellows case, he still creates >50 degs of shoulder horiz abduction.

Torso kinematics:

- trunk opens early into foot plant (>30 degs). Limiting hip/shoulder separation (28 degs).
- Stays stacked pretty well though, doesn't leak/pull off early (12 degs of lateral trunk tilt at foot plant
-

Lower half and Rotational Velocities:

- Lead leg extension velocity is very above average (600 deg/sec)
- Pelvis is open at foot plant (51 degs), allowing the lead leg block to facilitate additional hip rotation
- Pelvis and other rotational velos well above average 🔥🔥🔥

Sequencing:

- Pretty fire. Everything looks to be in order:
Pelvis ➡️ Torso ➡️ Arm ➡️ Ball 🔥🔥🔥
- Timing: delay between peak pelvis and peak torso rotational velocity (0.0521 secs) is great. Making up for below average separation with above average timing.
