Marc Rzepczynski is a relief pitcher for the Seattle Mariners. In 2018 he struck out 11 batters over 10.1 innings across 23 appearances, going 0-1. His ERA of 6.97 was 67.9% higher than the league average of 4.15. Stripping out defence, his 6.45 FIP suggests he pitched better than his ERA shows. He missed bats on 30.9% of swings (13.6% of every pitch he threw), walked 17.5% of the batters he faced and struck out 19.3%. 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.

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.
