What might appear to be the shoulders turning through contact, is mostly follow through, and this is after the deceleration of the hips/torso/shoulder and lead arm. Which accelerates the the bat to it's peak velocity.

You will not achieve your best bat speed or highest velocity, because there isn't enough deceleration to funnel the energy completely into the bat. <<<

If I were to swing a ball around on a string, would you say the ball would continue to accelerate as the hands angular acceleration continues to increase? Or, would you say the balls maximum speed occurred because the hand began to decelerate?

Jack,

The problem with science is doesn't always apply well to a topic such as hitting.

Let's say we are talking about a Bonds swing on a inside pitch coming from a RH pitcher. This would be the closest to your analogy of tire wrench prong. And lets say he has some shoulder rotation after contact.

In this case the radius of the swing shortens before contact, tightens. In any case the front arm would still decelerate and the top hand will pass the bottom hand.

And since we are talking about a LH batter, with a pitch coming right into his wheel house there is going to be some rotation after contact. Some of it a release, and some of it momentum.

Tom,

I haven't read what you posted on the golf swing, and need to look at the Aaron clip. Aaron was a little different, and that in his younger playing days he had strong forward movement. And instead of going short to long, he made the pitch more or less jam him, and out of necessatity created a sharper shortening of the radius as he seemed to let the ball get deep.

This can be seen in many of his swings. So he seemed to take an inside pitch approach on many of swings, even when the ball wasn't far enough inside to require such a swing.

Judging by your golf post, you seem to be a little confused, and the article might be adding to this confusion.

Here is the most consistent person on earth to consistently hit the ball longer then anyone else.
