Andrew Alvarez is a starting pitcher for the Washington Nationals. In 2026 he struck out 65 batters over 69.1 innings across 17 appearances, 9 of them starts, going 2-3. His ERA of 3.76 was 9.9% lower than the league average of 4.18 — 6th of 15 on his team, and 217th of 467 among MLB pitchers with 20+ innings. Stripping out defence, his 3.10 FIP suggests he pitched better than his ERA shows. He missed bats on 26.6% of swings (12.0% of every pitch he threw), walked 10.8% of the batters he faced and struck out 22.0%. His 1.4 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.
