Blaine Boyer was a relief pitcher for the Kansas City Royals. In 2018 he struck out 9 batters over 21.2 innings across 21 appearances, going 2-1. His ERA of 12.05 was 190.3% higher than the league average of 4.15 — the worst on his team, and the worst among MLB pitchers with 20+ innings. Stripping out defence, his 8.33 FIP suggests he pitched better than his ERA shows. He missed bats on 14.2% of swings (6.7% of every pitch he threw), walked 11.9% of the batters he faced and struck out 8.3%. His -0.9 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.
