Quinn Mathews is a starting pitcher for the St. Louis Cardinals. In 2026 he struck out 39 batters over 44.1 innings across 8 appearances, 8 of them starts, going 2-3. His ERA of 3.65 is 12.5% lower than the league average of 4.18 — 5th of 16 on his team, and 195th of 538 among MLB pitchers with 20+ innings. Stripping out defence, his 3.80 FIP suggests the ERA was no fluke. He missed bats on 26.4% of swings (12.0% of every pitch he threw), walked 9.5% of the batters he faced and struck out 20.5%. His 0.7 dbWAR is built from that FIP rather than runs allowed, so it credits him for what he controls and not for the defence behind him.
