This open top hand allows the bat to be supported but not allow significant forces to be transmitted to the bat. Even simpler would be a one arm swing, but this way allows the bat to be supported and thus easier to swing. >>

Hi Marlin,

I have noticed that many a hitter will whirl the bat around with the arms until they start to tag in a noble, albeit unsuccessful, attempt to unearth "CHP" and "torque."

Everyone on the site lauds Jack's study on CHP, and rightfully so, for without it, even the most rudimentary amount of bat propulsion cannot be attain. The question that must be answered now is not whether CHP exists, but whether or not the swing involves torque.

One common synod argues for existence, positing that the diametrically opposed rotary movements of the torso and limbs will cause both hands to pinwheel around each other.

Another collective agreement argues that, since the limbs are doing all the work (a la Paul Nyman), rotation is merely a "reactive" force.

As for me, I err on the side of consensus. Initially, I believed in both torques before questioning how the hands can have an appreciable effect on torquing the bat if the grip on the bat becomes light at contact. This belief in doubting the existence of torque in a baseball swing--brought upon by experimenting with the idea of whether or not the hands can be active when a greal deal of centrifugal force is wrapping the bat around the body--slowly gravitated towards the position of whether or not there has not been a decisive amount of information to credit or discredit the role of torque in the swing. As a result, I became an agnostic. This is where I stand today.

It is also why I hope that a debate between Adair and Mankin will take place, and, hopefully, Epstein.
