As the clip below illustrates, a plot of their bat-paths shows that the bat-head also follows a circular path.

Jimmy,

I know you want to hear from Jack, but I have a couple of questions and statements. It appears by your post that you agree that the hands take a circular path. If the hands are on a circular path how can the bat path be linear? Do you agree that the bat works around the hands? If yes, Then there is no way the bat can be linear. The only way to move the barrel linear would be to stop the CHP and push your hands at the ball. Even if you pushed the Knob of the bat at the ball and left the barrel back, so you could snap it down with your wrists once your arms were extended, the barrel would still be moving in a circular path around your hands.

If the hands have a CHP and the bat is working around the hands, then the bat has to have a circular path as well.
