To me it seems cocking your wrist with a baseball and doing something with it is certainly easier than doing that with a softball.
Please tell me who is advocating cocking the wrist?????! I can't think of a single post in this thread where I or anyone else advocates cocking the wrist.
Further, if it's true that the wrist provides "a mere 5 percent to velocity," the pitcher should completely ignore it? Is that 5 percent just the wrist of the action of the wrist and fingers together?
Look back at that Sarah Pauly clip above. Boy, there is a lot of wrist action there. Do I think her wrist was cocked going into release. NOPE! Do I believe her wrist/hand/fingers intensified the energy coming from up the chain? You bet!
Further, there is no doubt that most of the energy comes to the wrist/hand/fingers from up the chain. But one sure way to take velocity off the ball (like for a change up) is to reduce the flexion in the wrist/hand/fingers.
Boardmember, Rick Pauly, Javasource, other experts..... am I wrong?
