Terry-

This is a great way to look at mechanics,just as in Paul Nyman's sequential still shots of Nolan Ryan.I wanted to comment briefly on the lower body/upperbody/axis of rotation.He keeps the axis back so nicely.What is the time interval between frames?

In Edgar you can see how the torso stays back while the lower body starts rotating forward.The last bit of this stretching(what Epstein calls torque)happens as the back ankle has rolled and the back knee has turned.The torso only whips forward as the front heel comes down.The back elbow is down,but the bat still back at this point.He seems to have good connection as Jack emphasizes with great angular displacement as the shoulder turn starts.The back leg is just starting to drag behind the front in the last frame,indicating that the hip turn is slowing to whip energy into the torso turn before contact.
