Therefore the wrist remains perpendicular (straight) to the bat as it rotates. – As I described earlier, the forearm rotates is sync with the bat’s rotation – this allows the wrist to remain straight as THT is applied.

> Shawn, the bat-head rotates rearward from its launch position back to the lag position. Common sense tells me that for the top-hand to aid in that rearward acceleration, it must be applying a rearward force. However, according to you, the top-hand is not applying a rearward force (pulling rearward with the fingers). Therefore, according to you, the top-hand is either going along for the ride, or, it is driving forward. Neither is true in a high level swing.

> Rotation along does induce a rearward acceleration of the bat-head. However, the rearward acceleration of the bat from rotation alone is limited. To attain maximum acceleration, the best hitters apply THT as I demonstrate in this clip -- http://www.batspeed.com/media/THTHigh.wmv

Jack. Based on the clips, do you believe Sammy Sosa is applying top hand torque? He and Jim Thome appear to be taking their hands back in unison to the launch position. Barry Bonds and Ted Williams use more of what you describe.
