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, Tom,
If the first clip doesn't answer your questions, this one should help.
I didn't anything fancy with the clip, I several slow motion swings of Pujols, and this is just the first one I pulled up. I actually forgot to place one point of reference at the elbow.
This isn't the best angle, and then again it's not to bad. Of course we would need an overhead view of the this swing to make any real definite answers or questions.
It doesn't take any rocket science knowledge or rocket science to explain what is happening, and is in complete compliance with what you see in the golf swing.
Same science, same results.
Like I said, I'm not going into any detail, and perhaps we can do this later.
Just wanted to show the clip.
Note that he doesn't make perfect contact, yet it still resulted in a HR to left-center.

Talk to you later,
