Please provide comments and recommendations on my son’s pitching. He’s 16, a sophomore, 6’2" 215 lbs, plays football as well as baseball. He’s not very flexible. This spring, when the video was taken he was throwing in the high 70’s. As the season went on (school baseball is a sumer sport here in Iowa), I’m sure he was throwing harder and faster, but was never measured.
What recommendation would you have to help him increase his speed? An other comments would be good too.
