Come on Bill. The screwball is the best pitch in the college game. lol. Other than the ball being angled in from one side to the other, I have never seen a screwball thrown that would even have the appropriate spin (which would be the direct opposite of the curveball spin) and has any kind of movement because it can't. The people who believe in screwballs are the same kind of people that come to one of your clinics and see you throw a riseball and are amazed. They are amazed because what they thought they were seeing over the years wasn't a riseball and low and behold you show them one that does indeed go up. They are watching this angled pitch, the screwball, and are thinking that it "moves". It boggles my mind when the whole topic of screwballs is discussed because virtually no one really throws one.
SoCalSoftballDad, I admit that I have not seen Stacy Nelson in person. I believe that I am very used to seeing the spin on thrown softballs and also looking at how the pitcher is releasing the ball. I have never seen a college pitcher with the spin that is opposite a curveball, which in my opinion would be a screwball. I have just not seen it. And the dumb drill that plenty of top college pitchers use to practice the screwball would break your arm if you actually did it at full speed. If the screwball was truly a pitch that was used and spun correctly, Stacy Nelson would not have to step so far left to throw it inside to a right handed hitter. She could step straight and break the ball inside like other pitchers break curve balls away. She is just a big strong girl who steps left and throws hard straight pitches inside to right handed hitters that can't turn on them and people think the ball is breaking inside. Doesn't happen.
