In 1889, Hall of Famer John Clarkson had one of the best pitching seasons ever by WAR. He won the Triple Crown with a 2.73 ERA, 284 strikeouts, and a win-loss record of 49-19. He also threw 620 innings, the most in the league and a total that represented more than half the combined workload of his team’s entire pitching staff. Although no one knew it at the time, his retroactively calculated ERA- was 64 and his FIP- was 82; both of those rates led the league among qualified pitchers.

Troy Taormina-Imagn Images Last year, I finished Shape+ v1.0, my attempt at a novel approach to pitch modeling, and submitted it to the FanGraphs Community Blog. However, I have since identified several issues with the original framework. In short, v1.0 included a random effect for “PitcherID” — it allowed the model to implicitly learn pitcher identity and use it as a crutch when generating predictions.
