JULY 4 • Associated Press

Placed on 15-day IL The Rockies placed Halvorsen on the 15-day injured list Saturday, retroactive to July 1, due to right shoulder inflammation.

Impact Halvorsen's most recent call-up to the big club didn't go well, as he yielded four runs on seven hits with a 1:1 K:BB over 2.2 innings spanning three appearances. He'll now be sidelined at least through the All-Star break because of a shoulder issue. Starter Tomoyuki Sugano (back) also landed on the IL on Saturday, while Sean Sullivan was called up from Albuquerque and veteran reliever Jordan Romano had his contract selected from the same Triple-A club.

Back up in big leagues The Rockies recalled Halvorsen from Triple-A Albuquerque on Wednesday.

Impact Colorado sent Halvorsen back to Triple-A on June 17, but he'll be eligible to rejoin the big club a week later after right-hander Jaden Hill (shoulder) was moved to the 15-day injured list in a corresponding move. The Rockies will likely limit Halvorsen to lower-leverage spots during his upcoming stint in the big leagues; the reliever has posted a 3.31 ERA in 16.1 innings with Colorado this season but has walked nearly as many batters (14) as he's struck out (16).

JUNE 24 • ROTOWIRE

Demoted to Triple-A The Rockies optioned Halvorsen to Triple-A Albuquerque on Wednesday.

Impact Halvorsen has turned in a 3.31 ERA through 16.1 innings with the Rockies this season, but he'll end up as the odd man out of Colorado's bullpen following Jimmy Herget's (shoulder) return from the injured list. Based on the results Halvorsen has gotten in both the majors and at Triple-A (2.45 ERA in 14.2 IP), he's a safe bet to rejoin the Rockies at some point when the team needs a fresh arm.

Charged with blown save Halvorsen blew the save in Monday's 5-4 loss against the Cubs. He allowed two inherited runners to score on a hit and a walk without recording an out.

Impact Entering with the bases loaded, no outs and the Rockies clinging to a one-run lead in the ninth inning, Halvorsen gave up an RBI single to Pedro Ramirez before walking Matt Shaw to bring in the game-winning run. While the runs were charged to Juan Mejia's line and he was saddled with the loss, Halvorsen was credited with the blown save in his first save situation of the season. The right-hander has split time between Triple-A Albuquerque and Colorado in 2026, posting a 3.31 ERA, 1.78 WHIP and 16:14 K:BB across 16.1 innings with the big-league club.

Back with big-league club The Rockies recalled Halvorsen from Triple-A Albuquerque on Saturday.

Impact Halvorsen had a brief stint with Colorado in late April, during which he pitched two scoreless and hitless innings while posting a 2:2 K:BB. The right-hander is back with the major-league club in a corresponding move to Jimmy Herget (personal) landing on the bereavement/family medical emergency list. Halvorsen will likely work primarily in low-leverage situations while up with Colorado.

Jettisoned to minors The Rockies optioned Halvorsen to Triple-A Albuquerque on Monday.

Impact Halvorsen was with the big club for a few days while Jimmy Herget was on paternity leave, making a couple scoreless appearances. With Herget returned to the active roster, Halvorsen is headed back to the minors.

Back in big-league bullpen The Rockies recalled Halvorsen from Triple-A Albuquerque on Thursday.

Impact Halvorsen wasn't able to win a spot on the Opening Day roster but will get a look now after yielded just two runs with a 12:5 K:BB in his first 10 innings at Albuquerque. His stay could be a short one, as Halvorsen is a good bet to be sent back down when Jimmy Herget returns from paternity leave.

Optioned to Triple-A The Rockies optioned Halvorsen to Triple-A Albuquerque on Tuesday, Kevin Henry of The Denver Gazette reports.

Impact Halvorsen entered spring training as a candidate for high-leverage work but pitched his way into a stint in the minors by yielding 12 runs with an ugly 4:12 K:BB over five innings of work. The hard thrower will try to get back on track at Albuquerque and could still have an important role in the Colorado bullpen down the line.

MARCH 24 • ROTOWIRE

Not expected to make roster Halvorsen is not expected to make the Rockies' Opening Day roster, Kevin Henry of The Denver Gazette report.

Impact There's no official move yet, but Halvorson does not have a locker in the team's clubhouse. The hard-throwing righty entered spring training as a candidate to serve as the Rockies' closer, but he struggled mightily in Cactus League play, allowing 12 runs with an ugly 4:12 K:BB over five innings of work. Halvorsen could still play an important role in Colorado's bullpen this season, but he'll work on honing his craft at Triple-A Albuquerque for a while. Victor Vodnik is the favorite to open the season as the Rockies' closer, but it's a bullpen situation fantasy managers would be best off avoiding.

Faces hitters Monday Halvorsen (elbow) tossed a live batting practice session Monday.

Impact Halvorsen looks to be free of restrictions in the opening weeks of spring training after he didn't pitch after Aug. 2 last season due to a mild right elbow flexor strain. Prior to getting injured, Halvorsen had seemingly established himself as the Rockies' preferred closer, though his numbers (4.99 ERA, 1.56 WHIP, 36:21 K:BB, 11 saves in 14 chances over 39.2 innings) weren't overly remarkable. Even so, Halvorsen still looks like one of the best bets for saves in Colorado entering 2026, given his raw abilities along with the lack of reliable alternatives in the Rockies bullpen. Halvorsen ranked third in the majors with an average fastball velocity of 100.0 miles per hour, and his 13.1 percent swinging-strike rate and 54.4 percent groundball rate offer hope that he'll be able to raise his strikeout rate and improve his ERA and WHIP.
