Randor Bierd was a relief pitcher for the Baltimore Orioles. In 2008 he struck out 25 batters over 36.2 innings across 29 appearances, going 0-2. His ERA of 4.91 was 13.5% higher than the league average of 4.32 — 9th of 18 on his team, and 325th of 482 among MLB pitchers with 20+ innings. Stripping out defence, his 4.63 FIP suggests the ERA was no fluke. He missed bats on 23.4% of swings (10.5% of every pitch he threw), walked 10.7% of the batters he faced and struck out 14.0%. 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.
