Yes the wrist in the LL CB is not twisted like the ML CB. The ML CB has a snapping motion where the wrist turns and the fingers spin the ball. An excercise that was given to my son was to snap his fingers and twist his wrist as he did the finger snap. Ofte when he was throwing his ML CB you would see him do this after throwing it to get the feel for throwing it. It is hard to describe. Most of my efforts were put into his mechanics and the coaches taught him his pitches. I watched his videos and picked up the wrist action and his arm was slightly bent as he snapped and twisted his wrist. Maybe Callaway can describe it better. I know that when he was taught the ML CB he was told to release it more out front and it would produce a tighter rotation and a sharper break that advanced batters would have trouble picking up. THe term LL and ML simply are a way of differentiating them in terms of hittability. He still throws the LL CB once of twice in a ball game. It looks like it is going in high and then tucks back in. Usually the batters shoulder relax and it is too late to reload.
