It seems to be getting worse and is causing her pitches to sail cause it aides in her glove arm to fly open (helicopter style). She's 5'7 and is 13 yo so she's still growing a bit. She pitched in front of U of Houston's hc last week and it was the first thing she noticed. Our pitching coach has been staying on her about it too. They both said she just needs to get stronger in her core which would probably alleviate this somewhat. Has anybody's else's daughter dealt with this? Suggestions please if so.....
