Halvorsen is among the candidates to open the season as the Rockies' closer, Patrick Saunders of the Denver Post reports.
Halvorsen made his big-league debut in 2024 after striking out 56 batters across 44.1 innings combined between Double and Triple-A. He converted two saves and two holds across 12 appearances with the Rockies, while also maintaining an impressive 13:2 K:BB. Tyler Kinley could get the first save chances due to his veteran status, but his inconsistent track record should keep the door open for Halvorsen and/or others.
