Karros will begin the 2026 season on the big-league roster, Thomas Harding of MLB.com reports.
Karros was the favorite to claim the third-base job coming into spring training, and his performance during the exhibition season aligned with those expectations. He collected 15 hits -- four of which went for extra bases -- and struck out only nine times in 41 plate appearances. Karros will presumably draw the majority of starts at third base to begin the season, though his role hasn't been defined.
