Pitch Movement


How this works: Every pitch is affected by the forces of gravity, which means that every pitch drops on its way from the mound to the plate. These numbers are reported with gravity, which makes them larger and different than other pitch movement numbers you may have seen. Since gravity requires time, and slower pitches aren’t ‘better’ just because they have more time to move, the movement of a pitch is compared to ‘average’ movement by comparing it to other MLB pitch types within +/- 2 MPH and from within +/- 0.5 feet of extension and release.
