Ron Mahay was a relief pitcher for the Minnesota Twins. In 2010 he struck out 25 batters over 34.0 innings across 41 appearances, going 1-1. His ERA of 3.44 was 15.6% lower than the league average of 4.08 — 6th of 14 on his team, and 144th of 467 among MLB pitchers with 20+ innings. Stripping out defence, his 4.23 FIP suggests that his ERA had some help behind him. He missed bats on 21.9% of swings (9.6% of every pitch he threw), walked 5.7% of the batters he faced and struck out 17.7%. 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.
