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 tracked version: induced break, spin rates, the numbers this page refuses to fake? 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.

Everything above wears its source. When you want the set again, start at the front door: the Pitch Index.

“The screwball's an unnatural pitch. Nature never intended a man to turn his hand like that throwing rocks at a bear.”
