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.

Every pitch type he threw, ordered by balls in play. Rows under 5 BIP are dimmed rather than dropped — a slider put in play twice is a fact about the slider.

2025 season, 1,970 pitches; percentiles vs MLB pitchers with 100+ that season. A description of the arsenal, not a grade: none of these predicted next season beyond Pitching+ and his own prior year. For shape scatter a higher percentile is MORE scatter.

Pitcher-positive, centred on the 2025 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.
