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.
Primary pitch: 4-Seam Fastball (58%)
Season Stats
