Ken Giles is a relief pitcher for the Seattle Mariners. In 2022 he struck out 6 batters over 4.1 innings across 5 appearances, going 0-0. His ERA of 0.00 was 100.0% lower than the league average of 3.97. Stripping out defence, his 3.11 FIP suggests that his ERA had some help behind him. He missed bats on 36.7% of swings (17.5% of every pitch he threw), walked 22.2% of the batters he faced and struck out 33.3%. 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.
