2023 Pitcher Power Rankings – Welcome to June

Welcome back to Pitcher Power Rankings! I haven’t put out a leaderboard for this metric in a while, despite publishing a top 30 at the end of April. The end of a new month presents a chance to update the list and see who has moved in the past 31 days.

To describe how this works, Pitcher Power Rankings is a formulaic ranking of every pitcher to appear in the 2023 season. Starting pitchers and relief pitchers, as well as those in a swing role, are all ranked together. These rankings are based only on performance in the 2023 season, not performance in prior years, and not projected 2023 performance going forward.

The formula used consists of park-adjusted run prevention and estimated run prevention metrics, as well as faster stabilizing pitch-by-pitch data, and volume of innings. The formula’s results are converted to a Score scale where 100.0 is a perfect Score, with the top pitcher for a full season usually posting a Score between 75.0 and 85.0.
