Horseshoe change.
Key is to verify with slow-mo vid, that she is truly getting her fingers to the outside of the ball,
and brush contact with the meaty part of the base of her thumb.
Also, you do not want to pull down the back side from 9:00-6:00 in a palm-up position, like other pitches.
Try and eliminate whip by getting the ball to *lead* the elbow to release, rather than lag.
Last thing, is make sure release happens at the hip, and she doesn't try and carry the ball further beyond that point and guide it in.
This will kill the spin rate, and make it a lolly-pop of a pitch for a batter to hit.
