>>> Thanks, that clip played. The point I am trying to make with shoulder rotation is that the shoulders have to get on a diagonal plane. Do you agree that the shoulders are not rotating parralel to the ground?

The back shoulder going down and the lead shoulder going up allows for the hips to turn while the shoulders are not opening. The shoulders are turned on a diagonal plane.

When I was discussing slicing the ball with shoulder rotation is what I see happen with kids who rotate there hips and turn hard with there shoulders, flying open with the lead shoulder which causes them to drag there hands and bat through the zone. They tend to pull off of the ball.

We may very well agree on the same thing but I do not emphasise shoulder rotation. IMO kids will pull hard with there shoulders and never let there hips power the swing. If they think about turning the shoulders vertically coupled with the barrel being turned rearward and then turned around the hands into the hitting zone, once the shoulders and hips become connected the barrel is fired through the contact zone. <<<

Hi Graylon

Bat drag is not caused by shoulder rotation. It is the results of the batter’s transfer mechanics not inducing enough angular acceleration to stay in sync with the rotation of the shoulders. As you pointed out, this requires mechanics that generate rearward as well as forward acceleration.
