J.B. Wendelken was a relief pitcher for the Arizona Diamondbacks. In 2022 he struck out 21 batters over 29.0 innings across 29 appearances, going 2-1. His ERA of 5.28 was 32.9% higher than the league average of 3.97 — 15th of 18 on his team, and 453rd of 546 among MLB pitchers with 20+ innings. Stripping out defence, his 5.01 FIP suggests the ERA was no fluke. He missed bats on 22.2% of swings (10.2% of every pitch he threw), walked 11.5% of the batters he faced and struck out 17.2%. 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.
