Ryan Buchter is a relief pitcher for the Arizona Diamondbacks. In 2021 he struck out 16 batters over 16.1 innings across 18 appearances, going 0-2. His ERA of 6.61 was 55.0% higher than the league average of 4.27. Stripping out defence, his 7.95 FIP suggests that his ERA had some help behind him. He missed bats on 22.7% of swings (9.9% of every pitch he threw), walked 16.7% of the batters he faced and struck out 20.5%. His -0.6 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.
