So about a month ago my DD (12u) developed a hitch in her swing.... She is lifting up on her toes as she swings the bat?!? She doesn't do it every time but enough that it's noticable and it's really taking her power away! She has always made good solid contact but since this issue has started her hits are weak grounders or pathetic infield popups. How do I fix this issue, she bats in the 4 spot so her team needs her back to 100%!!!
