David Aardsma was a relief pitcher for the Atlanta Braves. In 2015 he struck out 35 batters over 30.2 innings across 33 appearances, going 1-1. His ERA of 4.70 was 18.5% higher than the league average of 3.96 — 11th of 23 on his team, and 382nd of 513 among MLB pitchers with 20+ innings. Stripping out defence, his 4.86 FIP suggests the ERA was no fluke. He missed bats on 31.9% of swings (16.3% of every pitch he threw), walked 10.9% of the batters he faced and struck out 27.1%. 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.
