J.B. Wendelken is 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.
