Jason Adam is a relief pitcher for the San Diego Padres. In 2026 he struck out 22 batters over 34.1 innings across 38 appearances, going 2-2. His ERA of 2.62 was 37.3% lower than the league average of 4.18 — 4th of 19 on his team, and 53rd of 539 among MLB pitchers with 20+ innings. Stripping out defence, his 4.85 FIP suggests that his ERA had some help behind him. He missed bats on 28.5% of swings (14.9% of every pitch he threw), walked 7.0% of the batters he faced and struck out 15.5%. 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.

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.
