Adrian Houser is a starting pitcher for the San Francisco Giants. In 2026 he struck out 75 batters over 109.2 innings across 26 appearances, 16 of them starts, going 4-7. His ERA of 4.02 is 3.8% lower than the league average of 4.18 — 13th of 25 on his team, and 269th of 538 among MLB pitchers with 20+ innings. Stripping out defence, his 4.55 FIP suggests that his ERA had some help behind him. He missed bats on 18.1% of swings (8.4% of every pitch he threw), walked 7.2% of the batters he faced and struck out 16.0%. His 0.6 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.
