Luis Oviedo is a relief pitcher for the Pittsburgh Pirates. In 2021 he struck out 31 batters over 29.2 innings across 22 appearances, going 1-2. His ERA of 8.80 was 106.2% higher than the league average of 4.27 — the worst on his team, and 563rd of 567 among MLB pitchers with 20+ innings. Stripping out defence, his 5.66 FIP suggests he pitched better than his ERA shows. He missed bats on 27.7% of swings (11.2% of every pitch he threw), walked 17.7% of the batters he faced and struck out 21.1%. His -0.3 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.

How these are computed

wOBA uses linear weights measured from this season's own play-by-play rather than published constants, and wRC+ is park-adjusted against that same league. dbWAR is our own open implementation — not fWAR or bWAR — and the full derivation, including its simplifications, is on the methodology page.
