Michael Rucker is a relief pitcher for the Seattle Mariners. In 2026 he struck out 50 batters over 43.2 innings across 37 appearances, going 1-4. His ERA of 5.56 was 33.1% higher than the league average of 4.18 — the second worst on his team, and 453rd of 539 among MLB pitchers with 20+ innings. Stripping out defence, his 3.90 FIP suggests he pitched better than his ERA shows. He missed bats on 25.9% of swings (12.0% of every pitch he threw), walked 9.1% of the batters he faced and struck out 26.9%. His 0.4 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.
