Garrett Whitlock is a relief pitcher for the Boston Red Sox. In 2026 he struck out 59 batters over 52.1 innings across 54 appearances, going 7-2. His ERA of 1.72 is 58.8% lower than the league average of 4.18 — the best on his team, and 8th of 538 among MLB pitchers with 20+ innings. Stripping out defence, his 2.11 FIP suggests that his ERA had some help behind him. He missed bats on 31.5% of swings (18.0% of every pitch he threw), walked 4.5% of the batters he faced and struck out 29.8%. His 1.6 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.
