Tom Wilhelmsen was a relief pitcher for the Arizona Diamondbacks. In 2017 he struck out 17 batters over 26.1 innings across 27 appearances, going 1-1. His ERA of 4.44 was 1.9% higher than the league average of 4.36 — 13th of 18 on his team, and 297th of 527 among MLB pitchers with 20+ innings. Stripping out defence, his 5.32 FIP suggests that his ERA had some help behind him. He missed bats on 17.3% of swings (7.5% of every pitch he threw), walked 10.6% of the batters he faced and struck out 15.0%. 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.
