James Shields pitching mechanics (GIFs)

His glove side swings his glove hand so far down and below his knee that his lack of total body balance after delivery - lurches him off to the left really badly. That dipping and bending, over and over, would give me reason to work closely with his glove side patterns. Also his stride knee takes a terrible twist, all because of that glove side pattern(s).

On the other hand that last pitch that tailed away to the right looked like one nasty pitch to deal with.


I don’t think it’s a problem because he’s completely able to stabilize that entire front leg and rotate into it. The “unbalance” you see is really just the finish of an efficient delivery. I agree with you that, you wouldn’t teach the glove side swing down.


Change up.
