Rotate as needed. Belly button to the point of contact. You just aren't rotating as much.
We currently have a kid at NKU who can hit a ball to right, center or left off the tee from home plate over a 200 foot plus fence, so in my opinion it is more in the technic verses how far away the ball is.
I know how she grips the bat and that is how we apply leverage to the ball and it does make a huge difference since the ball is only the bat for about 2 milliseconds and the collision must be near perfect as to head down to engage the intrinsic muscle group and rotating as needed. Her grip is an off set grip or as a right handed hitter my top hand door knocker knuckles are line up to my wedding ring. The bottom hand has the bat in the area where the fingers join at the palm of the hand. We place a rubber band on the top hand index finger and tie about four knots and hold the bat so it lays across the hand so the bat is ahead of the index finger pad. This is a poor mans Turbo Slot glove. We have measured bat speed using the lining up of door knuckles and found this to give us a 2 to 4 MPH increase in bat speed using a Swing Speed Radar Unit.
Crystl's technic of using the back foot by first lifting the heel and focusing on the drive coming from the back foot big toe and the toe next to it and the knee cap pointing more in the direction of the second baseman for right handers verses short stop for left handers allows her to focus on an explosion of the hips that directs the ball to the opposite field by way of the belly button. As a right handed hitter it also helps her get out of the box faster.
This is why we teach bat control up the middle first and outside next as in my opinion anyone can pull a ball which is usually the case and the upper body is often out of sequence.
This is why using the matrix drill will uncover that in most situations the upper body is in motion prior to the Elvis move as Coach Enquist terms it or as the front foot heel plants the back foot heel is lifted and the thrust is set in motion for the rotation to begin. Some believe it is just rotation however the martial arts people will disagree with the baseball people. Personally I will stick with the martial arts people and that is how how Crystl does it and she has repeated it on pressure plates at UCLA with Slaught and Candrea and independent studies being done that may be published later on this year.
When we did this with Dan's daughter a few weeks ago it became clear as we did the matrix drill, ready position, set position, separate to toe touch and then when I said elbows she turned her shoulders before she planted the front foot heel (Elvis move) and pulled the ball and it was an outside pitch off the back corner of the plate. Then we repeated and she hit her mark on the net and you could hear the bat click which is an indication of good square contact with the bat much like driving a nail with a hammer. When the ball is deeper in the box remember we are in the lane with the knob of the bat sooner and need to focus on releasing the barrel to the ball. If we are late doing this we will not make square contact with the ball.
Many girls find using the nail simulator of how to use a hammer both vertically and then horizontally educational as most fathers over look the ability of using a $7 dollar hammer verses buying a $300 dollar bat and think unhinging the wrist happens from just centripetal force only. Once they learn how to control the release of the barrel to the ball the distance and bat speed pick up also.
The loading of the hips with counter rotation so they can feel the glutes in the back hip flex also helps to increase the force in their rotation as well as landing on a flexed front knee. This is a taught skill to the female as the glutes do not fire in a females knee which is why you see many females over the front leg verses being up against it.
A lot of coaches in my opinion struggle with this aspect of the swing and do not teach a stride or use a slide up against the back leg and reduce the power which can be generated by using a weight shift.
