DD is having difficulty with her arm slot. As her arm passes her hip from the back swing her hand can be six inches away from her body which means that when it's at 12 o'clock it's over her head. I guess it could be a chicken/egg situation but I think it's rooted in her glove shoulder dipping at push off. We do the kneeling drills to promote a true arm slot but it can get lost in translation during delivery. Any other drills I should know about? (I had her alternate casual underhand throws with pitches yesterday, as she doesn't dip doing those.)
