>>> Jack out of curiousity, to what degree do you believe the pre-launch bat sweep into the plane contributes to batspeed and could it ever diminish returns in accuracy, due to higher level pitching. I agree that it exists, but many are way more excessive and yet they are not always better hitters. Some that I view as not being excessive, but great hitters are Nomar and MCGwire. Some that seem excessive are Tejada and Aaron. Is the degree that one sweeps the bat into the plane a personal thing in your view? One could argue that this is the line between batspeed and bat quickness? Do you agree? <<<

But bat quickness should be measured from launch (decision to “go”) to contact. Therefore, the time spent during the pre-launch phase should not be included when determining bat quickness.

What limitation do you think it places on his hitting performance? – Is the pre-launch torque phase essential to becoming a great hitter? Maybe not, but there must be a reason why an overwhelming percentage of the hitters that can hit for both power and average exhibit it in their swings.

> This whole thread on pre-launch sweep is fascinating. Your video doesn't make any mention of it all, yet it appears that most great hitters use it, and from your comments on the video clip above, that it actually distinguishes between an average swing and a great swing.

> I'm still not sure though I understand why there isn't a difference between bat speed and bat quickness. If I define bat quickness as the time it takes to hit the ball from the launch position, then bat quickness depends not only on bat speed but swing length. Looking at video of Rose, Cobb, and other classic singles hitters, it sure looks like their position at launch has the bat pointed more behind them then towards second base. In other words, the swing of a Rose is shorter than a Griffey or Shawn Green. One might argue that the Rose/Cobb swing is quicker but has less bat speed, thus they're a singles hitter.

I agree JJA. Maybe quicker could be defined better if we said takes less time to implement or develop. It gives us more time, which many of us who have hit 90 MPH plus are looking for.
