Deolis Guerra was a relief pitcher for the Oakland Athletics. In 2021 he struck out 62 batters over 65.2 innings across 53 appearances, going 4-1. His ERA of 4.11 was 3.6% lower than the league average of 4.27 — 8th of 14 on his team, and 274th of 567 among MLB pitchers with 20+ innings. Stripping out defence, his 3.96 FIP suggests the ERA was no fluke. He missed bats on 28.4% of swings (13.7% of every pitch he threw), walked 7.4% of the batters he faced and struck out 23.0%. 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.
