I am a pitching coach and I have an 11 yr old who has learned a very weird pitching habit of leaning way over to the right and throwing side armed. She is releasing the ball close to a foot away from her leg. She amazingly throws strikes somehow. Anyway, I have gotten her to stand up straighter but she is still throwing sidearmed. I have tried putting her next to a wall and pitch and i have also had her using some weighted balls. I'm trying to just go back to basic mechanics. Do you have any suggestions on drills?
