Pitch flight
Flight parameters
Softball spin & axis
Index and middle fingers across the top arch. Thumb on the lower seam beneath the index finger.
Red stitches show rotation. The blue line is the spin axis; gyro tilts it toward or away from you.
Slow motion makes the seams easier to follow. Real-time rotation can appear to strobe on a screen.
