Jacob Waguespack is a relief pitcher for the Detroit Tigers. In 2026 he struck out 35 batters over 47.0 innings across 35 appearances, going 2-2. His ERA of 2.49 was 40.5% lower than the league average of 4.18 — the best on his team, and 45th of 539 among MLB pitchers with 20+ innings. Stripping out defence, his 4.55 FIP suggests that his ERA had some help behind him. He missed bats on 25.4% of swings (11.9% of every pitch he threw), walked 9.8% of the batters he faced and struck out 19.1%. His 0.1 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.
