About

Pitch Lab

Features
Read full description

Pitch Lab is a baseball pitch simulator for comparing how velocity, spin rate, and spin axis change pitch movement. Choose pitch types such as sliders, curveballs, forkballs, fastballs, and two-seamers, then adjust aim, handedness, velocity, spin, and spin axis. Use multiple viewpoints to compare trajectory, break, arrival point, and pitch shape. Pitch Lab is not a radar gun or measurement tool. It does not read real pitch data from sensors or video. It visualizes simulated trajectories from the parameters you choose for pitch design, coaching, bullpen discussion, and baseball training.
