Zach Stewart was a relief pitcher for the Chicago White Sox. In 2012 he struck out 19 batters over 35.2 innings across 20 appearances, going 1-4. His ERA of 8.58 was 113.7% higher than the league average of 4.01 — the worst on his team, and the second worst among MLB pitchers with 20+ innings. Stripping out defence, his 7.55 FIP suggests he pitched better than his ERA shows. He missed bats on 16.0% of swings (7.9% of every pitch he threw), walked 2.4% of the batters he faced and struck out 11.3%. His -1.2 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.
