Los Angeles Dodgers acquire reliever Seth Halvorsen from Colorado Rockies

The Los Angeles Dodgers have completed a trade with the Colorado Rockies, acquiring right‑handed reliever Seth Halvorsen in exchange for two minor‑league players, pitcher Nick Frasso and outfielder Landyn Vidourek. Halvorsen, 26, was on the Rockies’ 15‑day injured list with right‑shoulder inflammation and posted a 4.74 ERA over 21 appearances this season. He will report to Triple‑A Albuquerque for a rehab assignment before the Dodgers decide on a major‑league promotion.

Colorado received Frasso, a 27‑year‑old right‑hander who posted a 4.74 ERA in Triple‑A Oklahoma City, and Vidourek, the Dodgers’ No. 25 prospect, a third‑round 2025 draft pick currently hitting .176 in Single‑A Fresno. The trade reflects the Rockies’ effort, led by GM Josh Byrnes and president of baseball operations Paul DePodeda, to revamp a franchise that has endured three consecutive 100‑loss seasons.

The Dodgers, whose lineup tops the league in offensive metrics and whose starting rotation ranks first in ERA, view Halvorsen’s high‑velocity fastball (up to 103 mph) as a potential asset, despite his control issues. The move adds depth to a bullpen that ranked seventh in the league in ERA.
