Julian Merryweather is a relief pitcher for the Chicago Cubs. In 2025 he struck out 15 batters over 18.2 innings across 21 appearances, going 0-1. His ERA of 5.79 was 39.1% higher than the league average of 4.16. Stripping out defence, his 4.69 FIP suggests he pitched better than his ERA shows. He missed bats on 19.2% of swings (8.5% of every pitch he threw), walked 12.5% of the batters he faced and struck out 17.0%. 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.

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.
