>>> Please expain more; wrist binds, reverse wrist roll, what is that? <<<

Hi

The best way for you to understand wrist bind is to experience it for yourself. Take a launch position with the hands at the back-shoulder and the bat held vertical. Now, cock the bat-head toward the pitcher by raising the back elbow. Then, while keeping the bottom-hand still at the shoulder, accelerate the bat-head straight back toward the catcher by pulling back with the top-hand and lowering the elbow.

You should have felt a good deal of pressure building up in the top-wrist as the bat came down past your shoulder. Note that the palm of the top-hand was vertical (facing your shoulder or chest) as the pressure was building. At some point, this pressure will cause the palm to flip over past the palm-up position (reverse wrist roll) which results in causing the bat-head to flip below the swing plane – then back up toward the plane as the wrist roll back toward the normal palm-up position.

As I told Larry in another post, this flaw is difficult to detect unless you know what you are looking for. The “reverse wrist roll” will appear as a meaningless blur of the hands to most observers.
