My opinion, without video, is that no drill will correct this without understanding where the breakdown is in her process. Watching, recording, and reviewing to see what she's doing is the start. Then, work from the bottom up. If the foundation isn't good, so is the same for anything built on it.
My DD from 10u-12u was a very consistent and strong hitter. But, she was playing at the C-level. She benefited from slower pitching and weak defenses. High fly balls wouldn't get caught in the OF, and hard grounders would eat infielders up. However, her load and stride were not good. She would always dump her weight on the front leg and be forced to pull the trigger. Resulting in being early and god forbid a pitcher threw something off-speed. If I was the opposing coach/pitcher, I'd just throw changeups at her all game.
When she joined a first year 14u B program, she started striking out more, more foul balls, and a lot of pop-flys. I mean, A LOT. She's short (5' 2"), strong, and has fast hands. Her issue, has been in the bottom half. Finally, due to her increasing struggles at the plate, she's been willing and wanting to work. She's sort of hard headed that way. The last few months she's been willing to adjust her load, stride, and practice process to correct some issues. While, far from perfect, she's already seen positive results in her timing and better contact. But it's a process that will take a long time and she (and I) have to be patient.
