I know the higher the string is the sharper the break must be.
She threw a rollover. A rollover is a difficult pitch to throw well. On the other hand, most pitchers don't throw a drop very well.
There seems to be a real lack of understanding of exactly what the hand does when throwing a rollover. This spring, we did a video of my DD throwing the drop and focusing on the hand movement. Here it is:

If you download the pitch sequence, you can blow it up some and see the hand motion more clearly. One thing of importance is that the the ball is in the fingers and well away from the palm.
Still have the video? I can't access the link above.
Thanks.
