>>> This...

""The energy from hip rotation must be biomechanically transferred upward to induce torso rotation, which induces shoulder rotation which induces the accelerating the arms, hands and bat. – Once again, the value of hip rotation is its contribution to shoulder rotation.""

...is simply incorrect and not supported by video of the best players.

And, is easily understood if time were spent in the batters box. <<<

Hi Teacherman

I think the overhead clip of Rose (Rose hip and shoulder rotation) I showed earlier, is video evidence that supports my statement. It clearly shows that during a good portion of his swing, his hips and shoulders are rotating together. It should also be evident to any open-minded observation that his hip rotation is contributing to his shoulder rotation.

In case you think Rose is just a singles hitter and my statement would not be consistent with power hitters, I will post a clip of my analysis of Bonds’ “hip to shoulder rotation.” It should be up in a couple days as a new thread.
