George Klassen is a starting pitcher for the Los Angeles Angels. In 2026 he struck out 24 batters over 27.0 innings across 6 appearances, 6 of them starts, going 2-2. His ERA of 3.67 was 12.3% lower than the league average of 4.18 — 8th of 22 on his team, and 197th of 539 among MLB pitchers with 20+ innings. Stripping out defence, his 4.73 FIP suggests that his ERA had some help behind him. He missed bats on 31.3% of swings (14.3% of every pitch he threw), walked 16.8% of the batters he faced and struck out 19.2%. 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.
