1st time post/ long time lurker! My son in his last three pitching starts has expierenced a pain in lower back that gets worse the more pitches he throws. Trainer has indicated that his straight up pitching motion after he delivers the ball is the reason why, and has indicated that the pain will continue as long as he continues to throw this way. His back does not bother him at his other positions, nor when he is at bat. Just curious if anyone else has dealt with this and what the outcome was?
