Dodgers acquire Seth Halvorsen from Rockies for two former early draft picks

PHILADELPHIA –– The Dodgers made their first trade of deadline season on Monday.

Just don’t expect it to make much of a ripple.

In the kind of lower-profile, depth-building deal the team has executed repeatedly in recent years, the Dodgers acquired right-handed reliever Seth Halvorsen from the Colorado Rockies in exchange for two minor-leaguers, according to The Post’s Joel Sherman and Jon Heyman. 

The Dodgers are sending back in the deal Nick Frasso, a former top-ranked pitching prospect who struggled with injuries over his career, and Landyn Vidourek, the organization’s 2025 third-round pick who has slumped in his first full season with single-A Ontario this year.

Halvorsen, 26, will report to triple-A, and had been on a rehab assignment recovering from shoulder inflammation.

A third-year big-leaguer with a 99 mph fastball, Halvorsen has 13 career saves with a 4.31 ERA in 75 MLB appearances. While those aren’t bad marks for a pitcher who calls Coors Field home (his career ERA+ is 114, or 14 percentage above league-average production when accounting for ballpark factors), command problems have become pronounced over the last couple seasons. This year, he has 15 walks in 19 innings.

The Dodgers shipped out two former early-round draft picks in the deal, highlighted by a former fourth-round selection in Frasso, 27, a Torrance native who was originally acquired by the team in a trade with the Toronto Blue Jays back in 2022.

Two years ago, Frasso had climbed to the top of the organization’s pitching prospects rankings, and was a consensus top-100 talent in the sport. But then, he missed all of 2024 with shoulder surgery, had a 5.49 ERA with triple-A Oklahoma City in 2025, then was released this offseason before re-signing with the Dodgers on a minor-league deal.

The right-hander had a 4.74 ERA in 21 appearances with OKC this year, getting put on the 40-man roster last month but never all that close to his MLB debut.

He will look for a fresh start now with the Rockies, whose new GM is former Dodgers executive Josh Byrnes.

Vidourek, 22, was only a year removed from being drafted out of the University of Cincinnati, but had hit just .170 in 59 single-A games this year.

He remains a top-30 ranked prospect in the farm system according to MLB Pipeline. But he is also part of a deep crop of outfield options that could block his path through the organization.

It might not be the last time before the Aug. 3 deadline that the Dodgers
