[quote=“mcloven”]Thanks Roger for those observations! Just to clarify… The three frames below that I pulled out of the video are consecutive, so they show the position before front foot strike and after…and should show when he tucks his glove.
To make sure I get it right visually: are you saying that in the second frame (when his foot first hits), his glove side should look more like the first frame (and perhaps the glove side in the third frame should be more like the second frame), so he would be closed/glove & elbow to the plate a little longer (be equal and opposite in those frames, as he is in the first)? That will help me explain it to him.[/quote]
Yes, that is exactly what I am saying.
Also FYI, here’s his external rotation:
[For some background, right now, he maxes out at 70mph. Usually “cruises” around 65-68mph in games.][/quote]
No concerns with his external rotation.
