The goal is to measure a pitch’s quality using only the inputs provided by pitchf/x. I’ve decided to use the same five parameters as Moore, also opting against adjusting for release point, and instead simply excluding all pitchers I classified as sidearm. I’ve tried to control for count and handedness as well. I’m calling the metric fxRV, as its units are in terms of run value.

Player Type Pitches Usage rv100 fxRV100 Velocity
Matt Thornton F4 857 75.04% -1.42 -1.27 95.74
