George Klassen, a 24-year-old pitching prospect in the Angels' farm system, is expected to make an impact at the major league level in 2026. Klassen was acquired from the Phillies and has a high-powered pitch arsenal, including a 96-98 mph fastball, plus cutter and slider. After some early struggles in Double-A, Klassen improved his command and ended the 2025 season strongly, earning a brief promotion to Triple-A. With limited rotation depth behind the oft-injured Grayson Rodriguez and Alek Manoah, Klassen has a clear path to either earning a spot in the Angels' starting rotation out of spring training or serving as an injury replacement during the season.

Why it matters

Klassen's potential impact could be significant for the Angels, who are looking to bolster their pitching staff and return to the playoffs in 2026. As one of the top pitching prospects in the organization, Klassen's development and ability to contribute at the major league level will be closely watched by the team and its fans.

The details

Acquired from the Phillies in exchange for Carlos Esteves, Klassen was seen as a pitcher with great stuff but command issues. However, he has shown improvement in that area, cutting his walk rate and going deeper into games as the 2025 season progressed. Klassen's pitch arsenal includes a 96-98 mph fastball, a plus cutter, and a slider that both produced whiffs over 40% of the time last season. The Angels are hoping that with a full spring training under renowned pitching coach Mike Maddux, Klassen can continue to refine his command and earn a spot in the major league rotation or bullpen.

  • Klassen was acquired from the Phillies prior to the 2025 season.
  • In his final Double-A start of the 2025 season, Klassen pitched 7 innings, allowing 3 hits, 1 run (0 earned), 2 walks, and 8 strikeouts.
  • Klassen received a brief promotion to Triple-A at the end of the 2025 season.
