jryan15, I also believe you have the open and closed terms backwards to the way most people refer to them.
With regard to her shoulder rotation, I feel like something is not right with her initial shoulder rotation in that she goes from open (facing batter) to completely closed as she strides. Then she has to recover her shoulders from the fully closed position to get back to a partially open position. I wonder if maybe she should not be turning her shoulders so far back that she has to turn them back forward again to release.
