Carlos Rosa was a relief pitcher for the Arizona Diamondbacks. In 2010 he struck out 9 batters over 20.0 innings across 22 appearances, going 0-2. His ERA of 4.50 was 10.3% higher than the league average of 4.08 — 8th of 15 on his team, and 303rd of 467 among MLB pitchers with 20+ innings. Stripping out defence, his 4.63 FIP suggests the ERA was no fluke. He missed bats on 15.0% of swings (6.3% of every pitch he threw), walked 13.5% of the batters he faced and struck out 10.1%. His -0.0 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.
