A pitch-by-pitch look at how far each throw moves off the expected spin path due to seam and gyro effects.

The filled ellipse represents the distribution of Magnus movement. The outlined ellipse shows the real movement. The space between them highlights how much non-Magnus force alters each pitch.

A simple way to see which pitches rely on spin and which get extra help from the seams.
