Jimmy Lambert is a relief pitcher for the Chicago White Sox. In 2023 he struck out 41 batters over 37.2 innings across 35 appearances, going 2-3. His ERA of 5.26 was 21.4% higher than the league average of 4.33 — 14th of 20 on his team, and 426th of 550 among MLB pitchers with 20+ innings. Stripping out defence, his 6.20 FIP suggests that his ERA had some help behind him. He missed bats on 27.2% of swings (12.3% of every pitch he threw), walked 11.6% of the batters he faced and struck out 23.8%. 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.
