Tatum
I do believe Tatum could use some ideas and drills to work on. Just what I notice is ; no hand/elbow/scap (whatever you choose to call it) loading. She pushes all forward, then spins.
Also, she is late on most pitches....I really don't like pitching machines...it has to be hard for a young child who hasn't build really good habits, to keep up with a machine set at high speed. Like pitching, I think the goal of hitters should be to develop the best 14+ year olds, not the best 10 year old. By the time a girl has reached the age she needs to worry about high speed, you should have some good pitchers for live bp. Build habits with tee work and front toss. Keep drilling load/be ready SLOW AND EARLY...and she should do well against any pitchers.
Last thought...with an older dd I am sure you know this, but a lot of people read that don't post....let your kid strike out!
