Justin Hagenman is a relief pitcher for the New York Mets. In 2026 he struck out 4 batters over 8.0 innings across 3 appearances, going 0-0. His ERA of 3.38 was 19.3% lower than the league average of 4.18. Stripping out defence, his 6.10 FIP suggests that his ERA had some help behind him. He missed bats on 12.3% of swings (6.1% of every pitch he threw), walked 6.1% of the batters he faced and struck out 12.1%. 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.
