Drey Jameson is a relief pitcher for the Arizona Diamondbacks. In 2026 he struck out 13 batters over 17.1 innings across 11 appearances, going 0-0. His ERA of 4.67 was 11.9% higher than the league average of 4.18. Stripping out defence, his 4.07 FIP suggests he pitched better than his ERA shows. He missed bats on 29.3% of swings (13.5% of every pitch he threw), walked 11.8% of the batters he faced and struck out 17.1%. 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.

Head to head
Put Drey Jameson 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.
