AJ Blubaugh is a relief pitcher for the Houston Astros. In 2026 he struck out 74 batters over 72.1 innings across 44 appearances, going 4-2. His ERA of 3.61 was 13.6% lower than the league average of 4.18 — 6th of 17 on his team, and 188th of 467 among MLB pitchers with 20+ innings. Stripping out defence, his 4.29 FIP suggests that his ERA had some help behind him. He missed bats on 28.6% of swings (14.0% of every pitch he threw), walked 10.8% of the batters he faced and struck out 24.3%. 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.

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.
