@Gambler Bob and @RADcatcher , Rachel Garcia doesn't know how to pitch? Dallas Escobedo throws the same rise.
The physics is pretty simple--it is the same as a boat rudder. Throw the ball so there are seams on the bottom 1/2 of the ball "into the wind" but no seams on the top 1/2 of the ball. The air is deflected by the seams on the bottom 1/2 of the ball downward, causing the ball to move up.
Garcia throws a bullet spin riseball. The NCAA conveniently has black logos on the ball near the spin axis.
It is very clear that the black label is spinning around an axis.
Here is Garcia throwing a fastball up in the zone that gets tatooed. Notice the spin axis in this pitch is in the black logo. (She was trying to throw a high inside pitch but caught too much of the plate.)
You can get see the the second pitch better at the 2:15:00 mark of this video.
Pardon? Never said it isnt or shouldnt be thrown.
Commented catching a pitcher who threw it successfully.
And about the usefulness of the spin on it deception.
