Jacob Waguespack is a relief pitcher for the Detroit Tigers. In 2026 he struck out 15 batters over 21.2 innings across 17 appearances, going 0-1. His ERA of 1.66 was 60.2% lower than the league average of 4.18 — the second best on his team, and 8th of 467 among MLB pitchers with 20+ innings. Stripping out defence, his 4.75 FIP suggests that his ERA had some help behind him. He missed bats on 28.0% of swings (13.9% of every pitch he threw), walked 9.5% of the batters he faced and struck out 17.9%. His -0.0 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.
