My daughter is a pretty good 12U hitter. However, this is her last season of 12U and the combination of being very comfortable with 99% of 12U pitchers and seeing some slower pitchers has her developing a bad habit of lunging out on her front foot. She's losing all of her power and weakly popping up or "poking" the ball. No matter how many times I tell her to stay back, or go to right field, or follow her mechanics, she won't make the adjustment. Any drills or tips?
