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.

Kevin Jairaj-Imagn Images Would you rather have a guaranteed $140 million today or a chance at $1 billion six years from now? That very well may have been the decision facing Konnor Griffin earlier this month, and we know which path he chose. The vast majority of us probably would have made the same decision as Griffin, who signed a nine-year, $140 million deal with the Pirates less than a week into his major league career.
