The vibe around Busch Stadium is different this January. Usually, by the time the Winter Warm-Up rolls around, fans are arguing about which mid-tier veteran starter the front office just overpaid for to "stay competitive." But right now? The conversations are about who is left to pack their bags. Honestly, if you haven't been keeping up, the trade rumors St Louis Cardinals fans have been obsessing over aren't just rumors anymore—they’re a full-blown roster purge.
Chaim Bloom, now officially steering the ship as the President of Baseball Operations, has essentially taken a sledgehammer to the old foundation. It’s a reset. Some call it a rebuild; others call it "about time."
The Big Three Are Already Gone
Let's get the heavy lifting out of the way. If you’re looking for news on Nolan Arenado, Sonny Gray, or Willson Contreras, you're looking at the wrong box scores. In a dizzying stretch of moves this month, Bloom successfully moved all three.
The biggest shocker was the Nolan Arenado deal to the Arizona Diamondbacks. It finally happened. On January 13, the Cardinals sent the eight-time All-Star and a chunk of cash to the desert in exchange for right-hander Jack Martinez. It feels weird seeing Arenado in a different uniform, but the move cleared massive future salary and opened third base for the kids.
Then you’ve got Sonny Gray and Willson Contreras. Both were shipped off to contenders earlier this winter. By moving these three, the Cardinals didn't just get younger—they hacked roughly $30 million to $40 million off the 2026 books. That’s the kind of flexibility John Mozeliak rarely had, or at least rarely used.

Is Brendan Donovan Next?
If you're wondering who the next "big fish" is in the trade rumors St Louis Cardinals cycle, look no further than Brendan Donovan. He’s basically the ultimate trade chip right now.
He’s 28, cheap ($5.4 million projected for 2026), and can play literally anywhere. Teams like the Seattle Mariners and San Francisco Giants have been hovering like hawks. Seattle, in particular, has had "ongoing discussions" involving both Donovan and lefty reliever JoJo Romero, according to Jeff Jones of the Belleville News-Democrat.
The Mariners want a bat. The Cardinals want more pitching. It’s a classic match. But here’s the catch: the Royals were reportedly in the mix too, but that interest seems to be cooling off lately. If Donovan stays, he’s the veteran anchor for a very young infield. If he goes, the return has to be a haul of arms.
The JoJo Romero Dilemma
Romero is a fascinating case. He was arguably the best lefty reliever in baseball for stretches of 2025, posting a 1.71 ERA in the second half. The Cardinals held onto him at the 2025 deadline, which some analysts called a mistake because his value might never be higher. He’s 29, approaching his final year of control, and fits every contender's wish list. Seattle wants him. Badly.

Who Is Chaim Bloom Actually Targeting?
It’s not all about selling. You can't field a team of 25 rookies and expect the fans to show up, even in a "reset" year. Bloom has been hunting for what insiders call "bounce-back" candidates.
- Griffin Canning: This is the name gaining the most steam. Jon Heyman reported that the Cardinals have real interest here. Canning is coming off a torn Achilles with the Mets but showed flashes of brilliance before the injury. He’s basically the 2026 version of a "buy low, sell high" candidate.
- Ryne Stanek: This one is already in the bag. The Cardinals signed the veteran righty to stabilize a bullpen that looks... well, thin.
- The "Six-Pack" of Kids: Bernie Miklasz has been talking about the internal competition for the rotation. With Gray and Kyle Gibson gone, there are over 50% of the 2025 starts up for grabs. Matthew Liberatore, Michael McGreevy, and Andre Pallante are basically fighting for their lives this spring.
The JJ Wetherholt Factor
You can't talk about these trades without mentioning why they’re happening. The Cardinals have a logjam of young talent, and they need to see what they have.
Oli Marmol recently admitted that JJ Wetherholt—the #5 prospect in all of baseball—has a legitimate shot to break camp with the big league club. If Donovan is traded in the next two weeks, that path becomes even clearer. Wetherholt is the future. Keeping him in Triple-A just to keep a veteran around doesn't fit the new Bloom philosophy.
Why This Offseason Feels Different
For years, the Cardinals operated in the "mushy middle." They were never bad enough to get a top pick, but never bold enough to truly contend with the Dodgers or Braves of the world.

This winter, they chose a lane.
By clearing the veterans, they’ve admitted that 2026 is a transition year. The goal isn't necessarily a World Series trophy in October; it's about finding out if Masyn Winn, Jordan Walker, and JJ Wetherholt are the real deal. It’s a gamble, sure. But as any fan who sat through the 2024 and 2025 seasons can tell you, doing the same thing over and over was getting pretty exhausting.
What You Should Do Next
If you're following the trade rumors St Louis Cardinals news, keep a close eye on the Seattle Mariners' transaction wire. If a deal for Brendan Donovan or JoJo Romero goes down, it’s likely going to happen before pitchers and catchers report in February.
Also, watch the waiver wire. The Cardinals have been active there, claiming guys like Justin Bruihl and Bruce Zimmermann (minor league deal) to provide depth. It’s not flashy, but it’s how you survive a rebuild without losing 100 games.
Check the spring training invite list. If guys like Quinn Mathews or Tink Hence get early starts in Jupiter, you’ll know the "youth movement" is ahead of schedule. The era of the high-priced veteran stop-gap is over in St. Louis—at least for now.
