larry, one of the things we would teach our guys was about (for lack of a better term) "slap the midget". We would throw wiffle balls to them nice and slow, and tell them to wait back and give it a little "love slap" at about 50%. Then with each toss we would have them get a little "angrier" and slap a little bit harder, until they were slapping the ball at 100%. There is a big difference between slapping and swinging. It's quicker. If a big guy comes at you about to take a swing, you have time to get out of the way because it takes him forever to get his hand to your face. But have you ever been able to avoid a slap from a female? Me neither. It comes so quick and often leaves more of a mark than that swing would if it had connected with you!
Hope I didn't lose you in my wordiness. We taught to "slap" the ball instead of "swing" at the ball. The "slap" theory allowed us to have a team batting average in the .320's with more extra base hits than any normal team should have hoped for.
