Choose a pitch from one of the drop down menus to plot the simulated trajectory with and without spin induced movement. The menu options are updated each day with the pitches with the largest induced vertical break (positive, rise and negative, drop) and horizontal break (glove side, think slider, and arm side, think sinker). A short primer on the process used to create this simulation can be be found here.

To see how spin rate, spin axis, and spin efficiency affect pitch motion, you can interact with the pitch editor.
