Jack,
I was hoping you could settle a discussion on negative rotation or pre-launch rotation.
When the batter is getting into the launch position by creating negative rotation, should the movement be created by a turning of the upper torso starting at the waist and then begin upper hand torque on the swing?
Or should the batters movement be generated by the shifting of weight from forward to rear leg?

I have heard the terminology, "show you're number to the pitcher", which would fall in line with the hip rotation, but a fellow coach has told me different.
