Grades describe this season's stuff and run prevention. They are not forecasts: on clean season pairs the model has not beaten naive persistence (RESULTS-MLB §13), so nothing here projects next season.

How to read these

Each row is his rank, 1 to 99, among all graded MLB pitchers this season; the tick is the median. Green is good for him, red bad, whatever the stat's direction (a low FIP ranks high). Grey circles are descriptive rates with no good direction, and n= in place of a rank means too few events to rank. Grades are descriptive, not forecasts.

How to read these

Raw rates with this season's descriptive ranks. Sample-adjusted (shrunk) rankings are not shown yet: the reliability constants behind them were measured on college data and are being re-measured on MLB. Until then a small sample here is a small sample — hover the leaderboard column for its event count.

Pitcher-positive, centred on the 2023 league mean (+0.01 RV/100). Ranks are descriptive: the year-to-year reliability of this mix on MLB has not been measured yet, so no cell is verdict-coloured. His actual run value minus this mix — execution — is deliberately not shown.
