Aaron Slegers was a relief pitcher for the Los Angeles Angels. In 2021 he struck out 25 batters over 31.0 innings across 29 appearances, going 2-2. His ERA of 6.97 was 63.3% higher than the league average of 4.27 — the second worst on his team, and 537th of 567 among MLB pitchers with 20+ innings. Stripping out defence, his 5.62 FIP suggests he pitched better than his ERA shows. He missed bats on 25.0% of swings (11.9% of every pitch he threw), walked 10.1% of the batters he faced and struck out 16.8%. 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.

Box-score and rate statistics only. wOBA, wRC+, FIP and dbWAR are measured against a full league season, and a postseason is a few teams playing each other for a month, so they are not computed for October.

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.
