He is NOT using his hands. Can't you see the bat tip forward and then back exactly in relation to his back elbow?
Also the front elbow. It is a weather vane movement as Epstein describes it. Watch the elbows.
He does use his hands after the back elbow drops down.
Many MLB hitters talk of keeping the barrel up. You can't have that thought and be twisting your top hand thumb rearward. The ARMS are making the barrel move.
JB - Tom G above references the Bautista clip on Tewk's site - its an interesting read. If you've ever looked at Tewks site, his quest started trying to replicate those too infrequent "blackout" swings" - the swings that produced surprising power with no extra effort and barely an feeling of impact. My college ball might have continued if I had learned 30 years ago that the back elbow slots when the hands turn properly. I didn't believe it until I tried it, but I think I hit the ball harder now than I did then. Try it yourself and see what you think.
