Grant Hartwig was a relief pitcher for the New York Mets. In 2024 he struck out 4 batters over 6.2 innings across 4 appearances, going 0-0. His ERA of 6.75 was 65.5% higher than the league average of 4.08. Stripping out defence, his 6.62 FIP suggests the ERA was no fluke. He missed bats on 28.6% of swings (11.9% of every pitch he threw), walked 12.9% of the batters he faced and struck out 12.9%. His -0.2 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.
