Value
Standard score (σ), not a percentile, vs all qualified pitchers — 0 = average, +1 = one standard deviation above the mean. Built from 5x5 category z-scores (like Baseball Monster).
Control & Efficiency
Strike-throwing and length profile — drives the Likely-QS / High-K/BB start flags. The bar under each stat is this pitcher's percentile vs 207 qualified MLB starters (100th = best — already direction-adjusted, so a low BB% or P/PA scores high).
Arsenal
Throwing hand and pitch mix (share of pitches thrown) — the traits the matchup ratings below weigh against each opponent's splits.
Season Stats
The big number is the actual stat. The bar below it is this pitcher's percentile vs 385 qualified MLB pitchers (≥30 IP) this season — 100th = best, direction-adjusted (a low ERA/WHIP/BB scores high).
