Cole Wilcox is a relief pitcher for the Seattle Mariners. In 2026 he struck out 28 batters over 27.0 innings across 23 appearances, going 0-0. His ERA of 4.00 is 4.3% lower than the league average of 4.18 — 7th of 16 on his team, and 261st of 538 among MLB pitchers with 20+ innings. Stripping out defence, his 4.10 FIP suggests the ERA was no fluke. He missed bats on 31.3% of swings (14.5% of every pitch he threw), walked 13.8% of the batters he faced and struck out 22.8%. His 0.2 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.
