Koji Uehara was a relief pitcher for the Chicago Cubs. In 2017 he struck out 50 batters over 43.0 innings across 49 appearances, going 3-4. His ERA of 3.98 was 8.8% lower than the league average of 4.36 — 9th of 14 on his team, and 212th of 527 among MLB pitchers with 20+ innings. Stripping out defence, his 3.79 FIP suggests the ERA was no fluke. He missed bats on 31.7% of swings (17.5% of every pitch he threw), walked 6.7% of the batters he faced and struck out 28.1%. 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.
