Adrian Houser is a starting pitcher for the San Francisco Giants. In 2026 he struck out 65 batters over 97.0 innings across 23 appearances, 14 of them starts, going 3-7. His ERA of 4.55 was 8.9% higher than the league average of 4.18 — 9th of 16 on his team, and 310th of 467 among MLB pitchers with 20+ innings. Stripping out defence, his 4.84 FIP suggests the ERA was no fluke. He missed bats on 17.8% of swings (8.2% of every pitch he threw), walked 7.3% of the batters he faced and struck out 15.3%. 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.
