after the pitcher releases the ball and follows through he usually pronates, is it unusual for someone to supinate instead?? because that is wat i do

If you are throwing a fastball and supinate after release, yes that’s not good. Pronating or holding the pronation protects the elbow from hyperextension.

what is your arm slot (3/4, submarine, sidearm, overthetop)

it should only happen with a high arm slot

try pronating before release

over the top

jesse litch pitching for the blue jays does it and he has a natural cutter like his fasball is a cutter
