Watching the Amanda video again I can see she rotates right at six o'clock. Good ligaments!
When a pitcher whips harder (faster) does this naturally lead to a better spin speed? Are those two connected –whip speed and rotation speed?
My thinking is this, rps and overall speed is directly linked to how long they can delay the forearm rotation and the power with which the blast through that rotation. If the palm starts turning too early then most the spin and speed is lost.
Thanks Java. I should have mentioned the pause of the upper arm as well. I've pointed it on the Finch, Scarbourgh and Pauly video to my girls many times. I tell them to think of how we crack a whip or a towel, the only way to crack that whip is to move the handle forward and then stop it rapidly to get the tail of the whip to crack. I've even thought of bringing a whip to practice and have them play around with it to understand the principle.
I've watched those finger releases on the above mentioned videos over and over. I noticed with the ball facing third right before wrist/forearm rotation--it is impossible to cock the wrist but the fingers do play a major role in the flight, axis and rps. The one video of Pauly's daughter at release shows her using the index finger as the last finger to touch the ball was different. I always thought the last finger to touch the ball, baseball or softball, was the longest finger. I tried a few pitches with my index finger...it wasn't pretty.
