Yoshihisa Hirano was a relief pitcher for the Seattle Mariners. In 2020 he struck out 11 batters over 12.1 innings across 13 appearances, going 0-1. His ERA of 5.84 was 31.1% higher than the league average of 4.45. Stripping out defence, his 5.70 FIP suggests the ERA was no fluke. He missed bats on 26.7% of swings (12.5% of every pitch he threw), walked 12.7% of the batters he faced and struck out 17.5%. His -0.1 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.
