Do you throw a screwball with internal rotation? If anything, I'd think it would use external rotation.
Are you saying a screwball is thrown by rotating the wrist? Like a motion that would turn a door knob? I would like to see some video of that. I know nothing about throwing screwballs but would assume for a rhp she would place her index finger along a seam and internal rotation would peel the index finger across the back side of the ball giving it screwball spin. Like dropball spin turned sideways. It doesnt seem logical that turning your wrist would create enough spin.
screwballs are for screwballs
That sounds about right Ken. I cant see the door knob thing working at all. Like the roll over drop discussion on another thread, I just dont see it. The ball is long gone before any "wrist twist" can take place.
Thanks
p.s.
I'm not arguing rollover drops dont exist just that the hand does not roll over the top and down the front of the ball. Must be something to it though because I see alot of kids doing it, or at least some wierd follow through attempt at it.
