Rubby De La Rosa was a relief pitcher for the Arizona Diamondbacks. In 2017 he struck out 12 batters over 7.2 innings across 9 appearances, going 0-1. His ERA of 4.70 was 7.7% higher than the league average of 4.36. Stripping out defence, his 4.98 FIP suggests the ERA was no fluke. He missed bats on 39.4% of swings (20.8% of every pitch he threw), walked 11.8% of the batters he faced and struck out 35.3%. 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.
