Zac Thornton is a starting pitcher for the New York Mets. In 2026 he struck out 27 batters over 39.1 innings across 7 appearances, 7 of them starts, going 3-2. His ERA of 2.52 was 39.7% lower than the league average of 4.18 — 4th of 16 on his team, and 53rd of 467 among MLB pitchers with 20+ innings. Stripping out defence, his 3.70 FIP suggests that his ERA had some help behind him. He missed bats on 19.4% of swings (9.7% of every pitch he threw), walked 7.8% of the batters he faced and struck out 17.6%. His 0.6 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.
