Following up on last week’s post on the NPA Velocity “holds,” here are some more high-speed shots of throws vs. holds and the arm action disconnection problems that occur as a result:

Pitcher A - 7oz Throw vs. Hold

“Pushing” in the Acceleration Phase

Pitcher B - 5oz Throw vs. Hold

Early Engagement with the Distal Wrist / Forearm

And for fun, a 5oz (regulation) throw vs. a 7oz heavy ball throw:

Pitcher C - 7oz vs. 5oz Throw

5oz vs. 7oz Throw – Very Little Kinematic Difference
