Austin Bibens-Dirkx was a relief pitcher for the Texas Rangers. In 2018 he struck out 33 batters over 45.0 innings across 13 appearances, going 2-3. His ERA of 6.20 was 49.4% higher than the league average of 4.15 — 17th of 20 on his team, and 483rd of 530 among MLB pitchers with 20+ innings. Stripping out defence, his 5.56 FIP suggests he pitched better than his ERA shows. He missed bats on 22.2% of swings (10.8% of every pitch he threw), walked 6.9% of the batters he faced and struck out 16.3%. 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.
