A different angle
on every pitch.

The camera stays behind the pitcher, looking toward home plate. 12:00 is backspin, 6:00 is topspin, and 3:00 and 9:00 are opposite directions of pure sidespin. Clock labels describe spin direction, not the physical rotation axle. The green line shows that axle. At +90° gyro the ball spins clockwise from this view; at −90° it spins counterclockwise. At either endpoint the clock setting no longer changes the rotation axis. This illustrates rotation only, not pitch trajectory.

Seam geometry follows Mathematical Equations for the Seams of a Baseball in 3D Space, using the paper’s spacing parameter a = 0.4. Stitches are evenly spaced along the curve. Ball markings are sourced from the Rawlings official MLB baseball product photograph.
