Derek Lee, Albert Pujols, Manny Ramirez, Papi, ARod, Vlad, the list can go on forever....they all have their head down, eye on the ball when they hit. Kappy was looking at CF when he missed the slider in his first AB.
EDIT: He missed the pitch so badly (by 8 inches or more) because it broke and he didn't move with it, something you see all good hitters do.
EDIT II: I'm well aware that you use your reactions to hit a FB, but you still keep your eye on the ball.
