Lucas Sims is a relief pitcher for the Chicago White Sox. In 2026 he struck out 10 batters over 10.0 innings across 9 appearances, going 0-2. His ERA of 4.50 was 7.8% higher than the league average of 4.18. Stripping out defence, his 4.79 FIP suggests the ERA was no fluke. He missed bats on 21.6% of swings (9.4% of every pitch he threw), walked 15.2% of the batters he faced and struck out 21.7%. His -0.0 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.

Head to head
Put Lucas Sims beside up to three others.
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.
