I've coached College and H.S. and never ran into this. If someone could give me a suggestion I would really appreciate it. My son is 13 and has a slightly above average arm when he throws properly. He breaks from his glove and locks out his elbow. He refuses to bend it through his motion. I have shown him video of his deliver and a professional's delivery. He still refuses to change. Anybody have a suggestion or drill to fix this? I am dying over here.
