Pre-HS his routine was to do no throwing at all from mid-November to mid-January.Basicly to give him a break,mentally & physically.Play some basketball for school.By the end of basketball season,he's got the itch to get back on the baseball field.I have been told that younger,growing arms need some shut-down time.As you can see by the amount of baseball he has played I thought this was a good idea.His arm is fine,thanks.
