I am having trouble getting my daughter to fee how to correctly release the ball. I have read and have been doing the drills suggested such as 3 and 12 oclock drill. She seems to have trouble getting the flex in her elbow and having her upper arm tricep area meet her body and have her lower arm accelerate. It seems like her elblow stays more locked and the follow through is long in straight pulling her throwing shoulder forward after the release. Any drills or suggestions to get her to feel the proper release.???
