I come bearing exciting gyroball info!
"To throw a gyroball, a pitcher holds the side of the ball with a fastball grip. The pitcher's hips and throwing shoulder must be in near-perfect sync, something the book refers to as "double-spin mechanics." As the pitcher rotates his shoulder, he snaps his wrist and pulls down his fingers rather than flipping them over the ball, as happens with curveballs. The rotation is side over side. When the pitcher lets go, he must pronate his wrist, or turn it so the palm faces third base. It's like a right-hander throwing a screwball, only instead of the ball last touching the middle finger, it spins off the index finger."
I have tried the mechanics in my room, and let me say that this hurts, i must be doing it wrong :? Can anyone try it and report back?
Edit: Also for the hell of it, in the article they mention Joey Niezer, and i searched this name in myspace, and found this
It seems like all of his info matches up, with the same high school and everything. Im not going to, but maybe someone could ask him for more info on the gyroball in his comment section?
