2025 Fantasy Outlook
Halvorsen, a seventh-round draft pick by the Rockies in 2023, made his major-league debut last August after compiling a 4.47 ERA and 1.47 WHIP across 44.1 innings between Colorado's Double-A and Triple-A affiliates. The 6-foot-2 right-hander featured a four-pitch mix headlined by a 100 mph fastball that he tossed 37 percent of the time, but it was his splitter (28 percent usage) and slider (16 percent) that produced the most swing-and-miss. Halvorsen pitched well enough in his limited big-league sample (13:2 K:BB over 12.1 frames) to earn save chances over the final few weeks of the season, recording two in three opportunities. The 25-year-old's minor league track record suggest ratios and walks might be an issue, but Halvorsen's raw talent stands out among other relievers in Colorado's bullpen. He's worth gambling on as a closer-in-waiting type for 2025, but his save ceiling is capped due to the team he plays for. Read Past Outlooks
In mix for saves
Halvorsen is among the candidates to open the season as the Rockies' closer, Patrick Saunders of the Denver Post reports.
ANALYSIS
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.
