My 13 Year old DD, RH Pitcher, has developed such a poor arm circle, she basically moves her arm out to the right as she begins up swing, causing her to go behind her body on the down swing, that she has lost velocity and control and she has pretty much stopped pitching because of it. She actually was throwing about 50-52 MPH last year and has not improved but has gone backwards. Any thoughts on how to try and correct this, is it a cause of something else? She has tried but she literally does not understand where her arm is during the pitch. She thinks or tries to do it correctly but is almost the total opposite.
