I only relief pitched two times in my life and yesterday was one of the days I relief pitched. In the beginning I was throwing overhand, but the umpire wouldn’t bite at the high strikes so I decided to move to side arm. When I pitched side arm, I got more strikes and it sorta baffled the batters. I was wondering, is it alright if I do overhand and side arm in a inning of pitching? or should I stick to one arm slot.
