Aaron Loup was a relief pitcher for the Los Angeles Angels. In 2023 he struck out 45 batters over 48.2 innings across 55 appearances, going 2-3. His ERA of 6.10 was 40.9% higher than the league average of 4.33 — the second worst on his team, and 486th of 550 among MLB pitchers with 20+ innings. Stripping out defence, his 4.36 FIP suggests he pitched better than his ERA shows. He missed bats on 20.8% of swings (10.5% of every pitch he threw), walked 8.7% of the batters he faced and struck out 19.5%. His 0.2 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.
