The Dodgers made their first real move of deadline season on July 20, and it barely cost them anything they'll miss. Colorado is sending over right-hander Seth Halvorsen, a 26-year-old power arm out of the bullpen, in exchange for pitching prospect Nick Frasso and outfield prospect Landyn Vidourek.
MLB Trade Rumors broke the deal as it came together.

The confirmation cascaded fast, with multiple insiders locking in the same names within minutes of each other.
Jon Heyman laid out the full trade: Halvorsen for Frasso and Vidourek.
Seth Halvorsen goes to Dodgers from Rockies for prospects Nick Frasso and Landyn Vidourek
Halvorsen is the classic buy-low bullpen add: big stuff, shaky command, and currently on the 15-day injured list with right shoulder inflammation, though he's already begun a rehab assignment with Triple-A Albuquerque. His 2026 line sits at a 4.74 ERA and 1.95 WHIP over 19 innings with the Rockies, so this isn't a proven closer walking into LA's bullpen — it's a talent bet the Dodgers are hoping their pitching development staff can fix.
Frasso is the more interesting name going the other way. The Dodgers originally got him from Toronto back in 2022 in the Mitch White deal, and for a while he looked like a potential mid-rotation piece thanks to a fastball that touches the mid-90s with plus spin. But a labrum surgery in late 2023 derailed his momentum, and he's been trying to find his old form ever since — a change of scenery in Colorado gives him a fresh runway.
Jon Heyman explained why the Dodgers were comfortable moving a top-25 outfield prospect.
Vidourek, an OF, is the No. 25 ranked Dodgers prospect. Frasso is a RHP. LA has perhaps the best collection of OF prospects ever assembled (DePaula, Sirota, Hope, more) so they are trading from strength
That framing matters more than the trade itself. Vidourek ranks as LA's No. 25 prospect, but the Dodgers currently have arguably the deepest collection of outfield prospects in the sport, and names like DePaula, Sirota and Hope are ahead of him in the pecking order. Trading him off isn't a sign the Dodgers are worried about outfield depth — it's proof they have so much of it that giving up a fringe top-25 arm barely registers.
For a team that already looks like the class of the National League, this is exactly the kind of deal that flies under the radar in July but shapes October. Halvorsen doesn't need to be a finished product to help — the Dodgers just need him healthy and functional in low-leverage innings while their farm system keeps churning out the next wave. Watch his rehab assignment in Albuquerque closely; how quickly he's activated will tell you how urgently LA wants him in the bullpen mix before the deadline crowd thins out.
