Brent Leach was a relief pitcher for the Los Angeles Dodgers. In 2009 he struck out 19 batters over 20.1 innings across 38 appearances, going 2-0. His ERA of 5.75 was 33.1% higher than the league average of 4.32 — the worst on his team, and 405th of 484 among MLB pitchers with 20+ innings. Stripping out defence, his 5.06 FIP suggests he pitched better than his ERA shows. He missed bats on 26.1% of swings (10.0% of every pitch he threw), walked 13.6% of the batters he faced and struck out 21.6%. 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.
