When it comes to arm angle, is it correct for a youth coach to change a pitcher’s arm angle? (Assuming player is not doing harm with current mechanics)
I have seen a very knowledgeable coach in my town change pitcher’s arm angles. Try and get kids to throw over the top. Result has been mixed results and decrease in velocity.
I know Tom House, Nolan Ryan, etc say to not change arm angle. I continually argue with this coach to not do this but he says it’s correct.
Any advice will help. Thanks!
