My 12U DD kills the ball at practice, cages etc. Coaches tell her the mechanics look good. But at the plate in a game she has no power, wimpy grounders or infield pop ups. Last year her 10U coach laid into girls for swinging at bad pitches or swing and misses. So now she just wants to meet the ball to put it in play. No power. How can I get her to let loose and try ripping some likes she does away from a game? I have tried talking to her about not being afraid to strike out or swing at a bad pitch sometimes. She agrees and really wants to try but when she gets to the plate during a game she does the light swing thing.
