She needs to load her rear elbow/arm before the swing to get her top hand into a position to throw the barrel instead of using so much bottom hand/front side.
She will also benefit from keeping her front foot from opening/pointing toward the pitcher. Keeping the front foot closed or square to the plate will allow for more leverage to be used from the backside and top hand.
If the front foot opens, the front knee will open too much, then the hip opens too much/too soon, etc...
There is a mechanical advantage, well documented in golf, for the front foot to open somewhat as the front heel is 'planted'. Fairly common to see it in the baseball/softball swing as well.
