Both feet in box. Leaned into pitch?

[Mountaincoach]

NSA rules. 14U tournament. Batter is in the box, and both feet remained in box the whole time. Batter has a lot of rotation with her swing and really rotates her hips to help you vusualize what happened. Inside pitch. Batter loaded up, then realized it was inside, and then rotated to the right in an effort to avoid being hit. Her feet never left their position in the box. The ball still hit her in the lower posterior left thigh. She trotted toward first base and PU brought her back and called a ball. He stated that she "leaned into" the pitch, and her left knee went over the edge of the plate when she turned. What say you?
