Enters free agency O'Loughlin opted out of his minor-league contract with Colorado on Wednesday, Ari Alexander of KPRC 2 Houston reports.

Impact O'Loughlin has spent all season with the Rockies' Triple-A affiliate, where he turned in a 6.91 ERA and 2.11 WHIP across 41.2 innings. Based on his poor resume, the 25-year-old's next opportunity will almost certainly be as minor-league depth.

Denied Opening Day roster spot The Rockies reassigned O'Loughlin to minor-league camp Wednesday.

Impact O'Loughlin reached the big leagues for the first time in 2024 as a member of the Athletics, making four relief appearances while giving up five earned runs on 13 hits and five walks across 9.2 innings. After being outrighted off the Athletics' 40-man roster in September and eventually reaching free agency in November, O'Loughlin linked up with the Rockies on a minor-league deal and was given a chance to compete for an Opening Day roster spot this spring. Despite tossing scoreless innings in each of his three Cactus League appearances, O'Loughlin fell short in his bid for a bullpen gig with the Rockies and is instead expected to begin the season at Triple-A Albuquerque.
