what do you think about letting the top hand go free mid swing, somewhat like manny ramirez or mark mcgwuire. obviously they're great, but what about for high school or college hitters? is it not an advantage (smooth swing) unless you're physically huge?

>>> Hmmmmm -- UCLA, many years ago, did a study and measured the bat speed of numerous college and pro ball players.

If you are in high school or younger, pay attention!!

You are just using very different language and doing an absulutely terrific job of describing many small, tiny details that most coaches never get into or perhaps even know about. I'd love to hear you and a PHD of Exercise Science or Kines. get into it...! But, you know what? I felt you implied "bad" to some of the "old terms" than was necessary or deserving. --- However, I enjoyed this site...I'll let you know what comes back from my discussions...Later! <<<

> > "Hmmmmm", those are some very impressive bat speeds when you consider that a 35 oz bat traveling 75 mph at contact can hit a ball over 400 ft (Professor Robert K. Adair, "The Physics of Baseball" -- and also from other studies.) The problem with most swing mechanics is that a good percentage of the bat speed attained is generated after the bat has rotated 20 to 60 degrees past the contact point, which is wasted velocity. But, 100+ mph is still most impressive regardless of where in the swing it occurs --- Scott, if you have a copy of that study, please e-mail it to me. I would like to know the equipment they used and at what point of the swing they took their readings.

> > Your question regarding pine tar and two gloves is well taken. But, I have many clips of batters with the angle between the wrists at launch is in excess of 100 degrees and some where the top of both hands were almost in-line. At contact the angle between the wrists was less than 20 degrees - something moved or slipped.

The two most consistent problems I found were (1) not initiating the bat-head cleanly into the swing plane and (2) binds and misalignment of the wrists -- some directly due to gripping too tight with the top-hand.
