Time stamps:
0:16 Delicate argument here
0:35 Derek Jeter used a lot of hands, but not an easy way to hit
1:30 Quickening with hands - particularly on inside pitch - exposes the handle a long time and causes jam shots and spinning off the ball.
2:00 "Barrel stays inside hands" decreases handle exposure
2:20 Barrel Release controlled more with torso, not hands
3:10 Allow hands to work "past the ball"
