This is a new product that helps with the grip of the bat and I have had many hitters ask me if they can use these in games. The Major League rule book states that "On the bat, for up to 18 inches from the knob, the hitter may use any material or substance to aid him in gripping the bat".
Does this product fall into this rule?
It's called "The Bat Jack", and it is connected directly to the handle of the bat.
