Knight,
I made/edited this clip of Whitney Larsen from Alabama for you and your daughter.
It is a subtle thing, but watch her rear shoulder - as she starts to launch the barrel her rear shoulder retracts as it drops (lateral tilt) - this allows a deeper barrel turn. Many times hitters are told to swing with level shoulders, but to get a deep barrel turn you need to allow your rear shoulder to drop. This allows her hands to work down to BUT up through the ball....
This is so important, the amount of other mechanics involved from doing this one thing that MTS has pointed out, is crucial,
Last session, while teaching this part of the sequence, i got the 'look".
UHHOOH, who told her to 'not drop her shoulder"? i thought ok, approach this softley, Ok, lets look at some clips"
i can hear the coversation at her house when she gets home already.
Among what MTS has said about the back corner, i like how the transition, from that lean over plate from launch, turning into tilt, working the back shoulder under, keeps the head in the proper spot.
S0 many kids, lean over the plate in their stance, and by the time the bat gets aroung, they are standing tall, shoulders still level, head getting yanked out, then get yelled at to keep their head in their.
Good advice MTS.
