Casey Lawrence is a relief pitcher for the Seattle Mariners. In 2025 he struck out 7 batters over 17.2 innings across 6 appearances, going 1-2. His ERA of 4.08 was 2.0% lower than the league average of 4.16. Stripping out defence, his 4.15 FIP suggests the ERA was no fluke. He missed bats on 14.2% of swings (6.5% of every pitch he threw), walked 1.3% of the batters he faced and struck out 8.8%. 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.

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.
