Higher axis rotation
« on: July 08, 2010, 02:03:57 AM »
What would be the effect on a ball's reaction if the axis rotation was greater than 90 degrees? I would assume the skid would be greater. What about the effect on the backend move (greater or smaller than the backend move of 90 degree rotation)? Would be the ball turn at a sharper angle with an axis rotation greater than 90 degrees (as compared with 90 degree axis rotation)?

I've watched videos of Jeff Lizzi and it seems as though he has an axis rotation higher than 90 degrees. Agree or disagree?

Disagree.  For over 90* of axis rotation, at release his fingers would have to be ahead of his thumb based on the line the ball is released on.  I'd estimate his rotation at 60 - 70*, but it's hard to tell when you can't slow the video down.  --  JohnP

Assume that your hand is paced in the strong hand position (MF @ 7o''clock and RF @ 8o''clock) as a right hander. If you were to release the ball with the fingers coming through and finishing in front of the ball, wouldn''t you get around 170 degrees(almost complete backspin)?

Strongly disagree. His fingers are roughly between 45 & 60 degrees, if that far. He does it all with his wrist under & behind the ball, in the first sequences of this video.
