Lots of good points so far but one thing I see that's not being mentioned is in the first two videos you posted, she is drifting forward. I put my cursor on the leading edge of her helmet at heel plant and then went frame by frame and saw a lot of drift. This video shows less drift. Almost none although it's hard to tell exactly because of the angle.I hear ya. This is a video my dad took at a game I was not able to attend. Different angle, but it's one of my favorites.
I understand the drift on the first pitcher because she was so slow which threw your DD's timing off some but the girl in the 2nd video was plenty fast and your DD still had some drift. Likely why that ball was just a double instead of a HR becasue she squared it up good.
We played Crosby in the pre-season tournament back in Jan. Hell of a squad then, can't imagine how good they'll be when your DD gets back. Good luck to you guys this year.
