My daughter has been pitching for 4 years and in the last year has developed a bad habit where her arm is bent too much and she is getting called for illegal pitches because it is outside the elbow. I am looking for drills that may help correct this issue. She somehow turns the ball backwards at about 10 oclock on the windmill motion and then in an effort to get it to face forward again for the release is coming away from her body. Her pitching coach has had her put a ball in a sock and do her arm circles grasping the top of the sock instead of the ball and this seems to help, but I am looking for some other tips.
