August 4, 2025 5:56 PM : Rockies interim manager Warren Schaeffer said Monday that Halvorsen has been diagnosed with a mild flexor strain in his right elbow and could be activated from the 15-day injured list prior to the end of the season, Thomas Harding of MLB.com reports.
Analysis: Halvorsen was pulled after just five pitches in his relief appearance in the ninth inning of Saturday's 8-5 win over the Pirates and landed on the IL a day later. The good news for Halvorsen and the Rockies is that the 25-year-old does not have a serious injury that would have necessitated surgery, and if all goes smoothly in his recovery process, he could be back in action at some point in the next few weeks. Halvorsen has collected a 4.99 ERA, 1.56 WHIP and 36:21 K:BB across 39.2 innings this season and has converted on 11 of 14 save attempts. Schaeffer mentioned Victor Vodnik and Juan Mejia as the top candidates to close games for the Rockies while Halvorsen is on the shelf.
