A.J. Achter is a relief pitcher for the Los Angeles Angels. In 2016 he struck out 14 batters over 37.2 innings across 27 appearances, going 1-0. His ERA of 3.11 was 25.9% lower than the league average of 4.19 — the third best on his team, and 109th of 512 among MLB pitchers with 20+ innings. Stripping out defence, his 5.85 FIP suggests that his ERA had some help behind him. He missed bats on 19.7% of swings (10.2% of every pitch he threw), walked 7.5% of the batters he faced and struck out 8.8%. His -0.5 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.
