I can’t believe we’re still having this discussion in 2018 (as I write this, for those of you finding it in the future as you ride along in your self-driving, flying cars) but it’s amazing to me how many players, parents, team coaches, and yes, even pitching coaches, don’t understand what the throwing arm should be doing on the back side of the circle. That’s the part where the ball goes from directly overhead to down and through release.
I see it when I’m walking through a facility or past a field where someone is giving a pitching lesson.
