Pitch Atlas

The shape map

Every pitch, by direction.

One catcher's-eye field: whether each filed pitch rides or drops, and whether it runs or sweeps, against a spinless ball at center. Flip the handedness to see the mirror — a slider runs the other way for the other arm.

A schematic arranged by each pitch's sourced shape language, not a measured trajectory. To read the poles — what ride, drop, run, and sweep mean and why a tilt of the spin axis produces them — see Spin & Movement.

Want the measured version — induced break, spin rates, the tracked numbers this page tells in shape language? That craft has its own keepers: Baseball Savant ↗ and the FanGraphs model primer ↗. How to read them without losing the feel is its own wing: Reading Models.
