Dario Alvarez is a relief pitcher for the Texas Rangers. In 2017 he struck out 17 batters over 16.1 innings across 20 appearances, going 2-0. His ERA of 2.76 was 36.8% lower than the league average of 4.36. Stripping out defence, his 4.63 FIP suggests that his ERA had some help behind him. He missed bats on 37.7% of swings (14.3% of every pitch he threw), walked 17.1% of the batters he faced and struck out 20.7%. His 0.0 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.
