Graylon is dead on.

There is no stationery axis. There are two pivot points....the hands and the rear hip joint.

As to the implication that the head must move if the rear hip moves forward is not founded in fact. There is a linear shift of the lower body forward.....the weight moves from the rear leg to front leg.....and this can be done and IS done by every high level hitter.....without any head movement.
