A critical frame is missing to be sure of what EXACTLYU is going on....but she certainly 'twitches' the barrel with her hands/forearms....and she does it quite suddenly.

She just doesn't know how to get a SnF benefit out of her lower body. Said another way, she is dragging a turned barrel (as much as a turned barrel can be drug) because there is no 'grab' from the rear leg, because there is NO SnF burst. No airport people mover.

Which explain her struggle against the good pitching.

And that analysis....from that analyzer....OH. MY. GOD.
