Pitch Movement Map

Each pitch type this pitcher throws regularly, placed by how the ball moves — sideways break across, rise or drop down the side. Each dotted ring holds about the middle 85% of the league’s pitches of that type, so a cluster sitting outside its ring is movement most pitchers don’t have.

The dots — a sample of this pitcher’s regular-season pitches, placed by movement: left–right is horizontal break, up–down is induced vertical break (what the pitch does beyond gravity). The view is handedness-neutral — positive break is toward the pitcher’s arm side for lefties and righties alike, so every sinker runs right and every sweeper breaks left, whoever throws it.

The dotted rings — about the middle 85% of where each pitch type lands league-wide (a 2-standard-deviation spread), measured from 7.5 million regular-season pitches since 2015. A cluster sitting well outside its ring is movement most of the league doesn’t get. Spring training and the postseason are excluded.
