Keiichi Yabu was a relief pitcher for the San Francisco Giants. In 2008 he struck out 48 batters over 68.0 innings across 60 appearances, going 3-6. His ERA of 3.57 was 17.4% lower than the league average of 4.32 — 4th of 16 on his team, and 142nd of 482 among MLB pitchers with 20+ innings. Stripping out defence, his 4.06 FIP suggests that his ERA had some help behind him. He missed bats on 20.4% of swings (9.0% of every pitch he threw), walked 10.6% of the batters he faced and struck out 15.9%. His 0.6 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.
