The Angels assigned Klassen to minor-league camp Friday.
Klassen's strong start to spring training put him in contention to make the Angels' big-league rotation, but it looks like the 24-year-old will open 2026 in the minors. One of the Halos' top prospects, Klassen posted a 3.86 ERA, 1.20 WHIP and 10:5 K:BB across 11.2 innings this spring.
