Gyroball


#1

Does anyone have any information on where to by gyroball training aids. CJ Wilson used a gyroball whistle. Or does anyone know where to get the gyro master baseballs? Any info would be great!


#2

To detect/evaluate gyroscopic spin on a ball, simply color half of a ball with a sharpie marker along the seam axis you care to practice with. Then throw true gyroballs and use video in line with the throwing arm to see how much color you can detect.

What ever happened to that pitch?
