2022 Review: Pitcher xERA Overperformers
Yesterday, I listed and discussed six pitchers with at least 150 innings pitched that most underperformed their Statcast xERA marks. Let’s now flip over to the overperformers. As you could guess, there are far more overperformers than underperformers. That’s because a pitcher is less likely to be allowed to record 150 innings if he significantly underperforms his xERA. At some point, results matter and teams don’t have the luxury of patience to wait for their results to match their underlying Statcast metrics. So pitchers that overperform are allowed to throw that many innings, even if their underlying metrics suggest impending doom. Until that impending doom actually occurs, they will keep getting the ball.
