I know we use the AS power drive video a lot here because of the high quality slow motion.

Something that I have been studying recently is the angle of the shoulders and hips at release.

Is AS too closed at the moment of release?

Amanda's shoulders do seem slightly too closed for what is considered ideal but hey...I'm not going to be the one to argue with her success. Her hips look great to me.

Lastly, when I use the expression “keep them open”, it is NOT a reference to their shoulder line at release. To me, keeping them open is a reference to a pitchers shoulder line when the upper arm contacts the side. At this point, they must be more ‘open’ than ‘closed’ (less than 45-degrees). Failing to do so will negatively impact their ability to fully decelerate and chain energy from the upper arm segment… and you’ll see the upper arm blast (or roll through) by their side. The degree of elbow flexion between pitchers makes the moment of side contact a large variable, so there is no magic time on the pitching clock. Here's the Jennie we love... and I view her as much more 'open' than 'closed':
