• Angels' George Klassen: Assigned to minor-league camp

  Rotowire Mar 20, 2026

  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.

• Angels' George Klassen: Could be candidate for rotation

  Rotowire Mar 12, 2026

  Klassen has had a strong spring training so far and may be looked at as an option for the Angels' Opening Day rotation, Rhett Bollinger of MLB.com implies. Alek Manoah remains the favorite for the team's fifth-starter role, but he's had two straight rough spring starts, surrendering nine runs with a 7:7 K:BB over 6.1 innings. That could open the door for the Angels to consider other options, and Jack Kochanowicz -- who's pitched well so far -- may be the lead candidate for the rotation should Manoah not get the role. However, Bollinger points that Klassen has excelled this spring, as the young hurler has given up just two runs while registering a 9:3 K:BB over eight innings spanning three appearances. Klassen isn't on the 40-man roster and has just one Triple-A outing under his belt, so he's probably still a longshot to open the season in the majors. He's one of the Angels' top prospects, however, and the organization certainly hasn't been shy in recent years about rapidly advancing prospects through the minors and up to the majors.

• Angels' George Klassen: Rolling for Trash Pandas

  Rotowire Sep 15, 2025

  Klassen has a 1.17 ERA, 1.26 WHIP and 32:11 K:BB in 23 innings over his last four starts for Double-A Rocket City. Klassen has some of the best pure stuff in the minors, and it's on brand for him to have a higher WHIP than ERA over this dominant stretch. He's cut his walk rate from 17.3 percent in seven starts at Double-A to close 2024 to 10 percent in 24 starts this year while logging a career-high 102.2 innings. His command still comes and goes, and he has six starts this year in which he has given up five or more earned runs, although he also has six starts with eight or more strikeouts. Klassen's below-average control may push him to the bullpen eventually, but the Angels figure to give him every opportunity to develop as a starting pitcher over the next couple years.

  The Phillies promoted Klassen from Single-A Clearwater to High-A Jersey Shore on Monday, Jonathan Mayo of MLB.com reports.
