Per the New York Post and New York Times, the Dodgers landed Seth Halvorsen from the Rockies. Los Angeles gets a high-upside relief arm with MLB experience, while the Rockies grabbed two Minor League prospects, Nick Frasso and Landyn Vidourek.
The Dodgers’ Return
- RP Seth Halvorsen (4.74 ERA, 17 K over 19 IP (MLB))
The Rockies made former Tennessee Volunteer Seth Halvorsen a seventh-round pick in 2023. One year later, Halvorsen was already in the Majors and among the rising relievers in the game.
Halvorsen struck out 13 over 12 IP during his initial taste of the Majors in the big leagues two years ago. The now-26-year-old entered the 2025 season as the Rockies’ closer to start the year but scuffled at points. Additionally, Halvorsen missed time with an elbow strain.
He started 2026 in Triple-A and has been on the shuttle between Albuquerque and Denver for much of the year. Most recently, he was placed on the IL in early July with right shoulder inflammation. Halvorsen was in Triple-A on a rehab assignment before the trade.
The book is pretty simple on Halvorsen. Primarily a pitcher who will use an occasional splitter, a slider, and the eye-popping pitch in his arsenal, a four-seam fastball that routinely sat 101-102 MPH.
Max effort pitcher who will walk a lot of batters. But at the same time, Halvorsen does not concede much well-hit contact.
Halvorsen is a pre-arbitration player.
The Rockies’ Return
- RP Nick Frasso (4.74 ERA, 40 K over 24.2 IP (AAA))
- OF Landyn Vidourek (.176/.340/.343, eight HR and 18 XBH over 61 GP (A))
Nick Frasso was in the Dodgers’ system for some time. The right-hander was acquired nearly four years ago from Toronto in the trade that sent Mitch White to the Blue Jays. Once a starting pitcher prospect, Frasso moved to the bullpen in 2025.
Now exclusively a reliever, Frasso has become an interesting reliever name. Hard fastball that topped out at 101 MPH with Triple-A Oklahoma City but sat mostly 96-97 MPH. Frasso has more of a fleshed-out arsenal, as the righty complements it with a cutter, a changeup, and a slider.
Given that Frasso was a starter for so long, that is not much of a shock.
Vidourek was a third-round pick by the Dodgers last year out of the University of Cincinnati. He was a three-year starter with UC, and his big year came in 2025 when Vidourek belted 14 home runs in his junior season. However, he piled up the strikeouts with the Bearcats, and that trend continued in 2026.
High swing-and-miss hitter, as Vidourek had a 40.1% Whiff% rate over the last month. However, he will take hit pitches and work counts, with a Take% above 58%. Hence, Vidourek walked 51 times, juxtaposed to 100 strikeouts across 61 contests with Low-A Ontario.
Analysis
Halvorsen slipped down the Rockies’ reliever depth chart since the 2025 season, as Juan Mejia, Jimmy Herget, and Victor Vodnik all have been used in more high-leverage situations than the hard-throwing righty. So, the move does provide the Rockies an opportunity to pad out the system in a rare intra-divisional trade.
Frasso is a good arm with good stuff, while Vidourek is a lottery ticket. And for the Dodgers, Los Angeles’ farm system is stacked with high-upside outfielders. Thus, it’s not an exorbitant price to pay.
Especially when taking into account the fact that Halvorsen, despite being a reliever, has tremendous upside. No, the Dodgers don’t need him to close, as the club has Tanner Scott and a rehabbing Edwin Diaz as among the many options to finish out a contest.
But winning teams always have significant relief depth, and bullpens that can give unique looks. Halvorsen’s velocity makes him a very unique reliever in his own right.
