That other thread on arm whip prompted me to post this clip of a pitcher who learned arm whip very easily. HOWEVER, she struggles with a lot of other things. We're still working on her lazy legs. And, I've noticed in my most recent clips of her that she's not getting her shoulders fully open by 12:00. In fact, I'm not sure she gets those shoulders fully open. Strangely her best pitch is a rise-curve. She's struggling most with the accuracy of her fastball/drop-ball. Of course, I'm interested in what the real pitching experts might suggest.
