> The ball comes in to fast to follow it smoothly all the way in when you think about the usual model of the visual system.At first the eyes don't have to move much to track,but as the ball gets close,the eyes can't move fast enough to stay focussed on the ball.The brain automatically resets the eyes fast and starts tracking again,a movement called a saccade.You will develop various strategies for watching the ball.One is to try focus on the ball at release,then switching focus to where the ball is anticipated to be at the last moment you can make a correction to the swing which is maybe 15 or 20 ft in front of the plate.It seems that those who try to turn the head or focus on the ball agin closer than this do not do as well.It also seems that what many hitters describe doesn't sound like they are using a visual system that corresponds to this model,but more like a different visual system for high speed tracking called the ambient system.The thread linked above gives more info along these lines.What is the question you feel is not getting answerred?
