First time on LTP. My 11 year old lefty pitcher has been pitching for a couple years now. Last year he was flying open and throwing side-arm. This year he can’t seem to stop cupping the ball and lifting elbow well above his shoulder. He has had an abundance of instruction but we can’t seem to stop this initial movement. The action is exacerbated when he tries to bear down and throw hard. Any ideas to get him to keep his elbow more in line w his shoulder and just being the ball to approx. 90 degrees prior to initiating his throwing motion? I see you have a video analysis section on here. Maybe someone can take a look?
Here is a video of him. Not sure how to upload it here. https://youtu.be/XPK_-g42S38
