Gabe Speier is a relief pitcher for the Seattle Mariners. In 2026 he struck out 45 batters over 46.0 innings across 54 appearances, going 2-3. His ERA of 2.93 was 29.8% lower than the league average of 4.18 — the best on his team, and 84th of 539 among MLB pitchers with 20+ innings. Stripping out defence, his 3.86 FIP suggests that his ERA had some help behind him. He missed bats on 24.5% of swings (12.7% of every pitch he threw), walked 7.9% of the batters he faced and struck out 23.7%. 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.
