My female cousin..she's about 12 or 13 now I think. I hit around with her the other day and noticed every time she hit her 2hbh it tended to go into the net and she had this weird twisting motion. I asked her about it and saw how she gripped the racquet. She holds her right hand continental but her left hand is up by the throat probably holding at least a 1/4 to 1/2 inch of throat. Is there anyway to fix it? I think she used to hold its there for support when she was hitting with her sister who's a #1 singles in her HS. It's now become a bad habit. Thanks in advance
