My DD has always been a strong hitter but here lately she has developed a bad habit of casting when she swings. She is rolling her wrist and driving everything into the ground. I need some helpful hints from all you veterans how to fix this problem. I've purchased an insider bat and we have been working with it and looks like it is helping some. She hits correctly for the most part when we are hitting off a tee but when we hit live pitching she tends to cast more often.
