José Buttó is a relief pitcher for the San Francisco Giants. In 2026 he struck out 5 batters over 2.0 innings across 3 appearances, going 0-0. His ERA of 22.50 was 438.8% higher than the league average of 4.18. Stripping out defence, his 17.09 FIP suggests he pitched better than his ERA shows. He missed bats on 40.9% of swings (14.3% of every pitch he threw), walked 25.0% of the batters he faced and struck out 31.3%. His -0.3 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 José Buttó 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.
