Another way of looking at what Jack is saying is that the batter has approximately one-tenth of a second to accelerate the bat to top speed. Any attempt to "crack the whip" and lead with the handle will give the hitter less time to reach a high bat speed. Therefore the batter will ulimately end up with a slower swing.
