>>>Releasing the top hand is also more of a necessity if the head is kept down facing the contact point as I believe Lau recommends. Epstein feels this head position may hamper rotation and recommends the head be facing out to the pitcher. <<<
Hi
I would be inclined to agree with Mr. Epstein. The swing plane and timing has been fully established when a fastball is about 12 to 15 feet away from the batter. Once the swing is fully initiated very little changes can be made to the bat’s trajectory. So, trying to track the ball’s flight past that point would be of little value.
