The Cardinals might be about to trade one of their most reliable relievers—and not everyone is going to agree with that move.
The St. Louis Cardinals have already signaled that this offseason will be active and possibly uncomfortable for fans, starting by sending right-hander Sonny Gray and $20 million in cash to the Boston Red Sox in exchange for two younger pitchers and a player to be named later (or cash considerations). That deal looks like just the beginning, and now attention is shifting to left-handed reliever JoJo Romero, who has reportedly been drawing steady interest from other clubs in the early weeks of the offseason. Teams looking for a proven, cost-controlled bullpen arm have clearly noticed what he’s done in St. Louis.
Romero fits the profile of a classic trade chip almost too perfectly. He’s an effective reliever, his salary is manageable, and he plays for a team that appears to be stepping back to retool rather than pushing all-in for 2026. On top of that, he’s only a year away from free agency, which means the Cardinals have a limited window to either extend him or convert his value into long-term assets. Current projections peg his 2026 arbitration salary at about $4.4 million, which would be his final year under team control before he can hit the open market. For front offices, that combination of performance, price, and contract timeline practically lights up as “trade candidate” on the spreadsheet.
Since arriving in St. Louis from the Phillies in 2022, Romero has gradually become a mainstay in the Cardinals’ bullpen, really cementing his role starting in the 2023 season. Over the last three years, he has thrown 156 2/3 innings with an impressive 2.93 ERA, pairing that with strikeout and walk rates that sit right around league average—roughly a 22.9% strikeout rate and an 8.5% walk rate. Those numbers show a pitcher who may not blow everyone away with sheer dominance but who consistently does his job and limits damage, which is exactly what contending teams want late in games. In the most recent season, his sinker averaged 93.7 mph, and he turned that velocity plus movement into ground balls on 53% of balls in play, helping him post a sparkling 2.07 ERA.
Romero has not just been a middle-inning arm; he has worked some of the toughest situations in the Cardinals’ bullpen. Over the past three seasons, he has racked up 12 saves and 57 holds, a clear sign that managers have trusted him when the game is on the line. Even more encouraging, he made a notable leap in effectiveness against right-handed hitters in 2025, holding them to a .220/.327/.315 slash line. For a left-handed reliever, being able to neutralize both sides of the plate matters a lot—it means he can stay in games longer and avoids being pigeonholed as a pure matchup specialist. That flexibility is one big reason other teams are circling.
But here’s where it gets controversial…
The argument for dealing Romero becomes stronger when you look at the current free agent landscape for left-handed relievers, which is generally considered underwhelming. There are some respectable arms available—names like Caleb Ferguson, Danny Coulombe, Hoby Milner, Justin Wilson, Caleb Thielbar, Drew Pomeranz, and Sean Newcomb all bring something to the table. However, most of those pitchers are well into their mid-30s or older, with Ferguson the only one in Romero’s age range at 29, while Coulombe, Milner, Wilson, Pomeranz, and Thielbar are 35 or above. Newcomb is 33 and has relatively limited recent success as a reliever. Compared with that group, Romero stands out as both younger and more consistently effective.
Because of that, his projected $4.4 million salary for 2026 actually looks like a bargain relative to what many of those older free agents might command on the open market. Contending teams that miss on top free agents—or simply don’t trust aging relievers—could view Romero as a more stable, medium-cost solution. For the Cardinals, that means the trade market for him might be considerably stronger now than it would be if there were several younger, high-end lefty relievers available in free agency. Put simply, scarcity drives value.
And this is the part most people miss: the Cardinals have been here before—and it did not go smoothly.
Last offseason, St. Louis found itself in a similar situation with closer Ryan Helsley. They had an elite bullpen arm, strong trade interest, and a decision to make: move him in the winter when lots of teams have flexibility, or wait until midseason hoping that the demand spike at the deadline would push the return higher. The front office at the time chose to hold Helsley, betting that the July market would reward their patience. Instead, Helsley turned in a good but not quite dominant first half, falling a bit short of the bar he’d set in the previous two seasons. The Mets ultimately did trade for him, but it’s fair to wonder whether the Cardinals left value on the table by not making a move months earlier.
So should they risk repeating that pattern with Romero—or learn from it?
Under new president of baseball operations Chaim Bloom, the organization appears to be leaning firmly toward the long game rather than short-term patchwork. Moving Gray is one clear sign, but just as important is Bloom’s repeated emphasis in public comments on strengthening the player development pipeline and rebuilding the roster with a long-term view. In that context, dealing Romero now fits the broader strategy: convert near-term pieces into younger, controllable talent that can help over multiple seasons. No team is going to offer a franchise cornerstone for a reliever, but Romero should still be able to bring back one or more prospects who can deepen the Cardinals’ minor-league system.
Keeping him, on the other hand, introduces real risk. If Romero struggles out of the gate in 2026, or worse, suffers an injury, his trade value could drop sharply or even vanish entirely. Contending teams are ruthless about recency when evaluating relievers; one bad half-season can change how an arm is perceived across the league. For a club that is openly prioritizing the long-term health of the franchise, rolling those dice might not make sense. That’s why many observers see a trade at some point this offseason as more likely than not.
Here’s a potential flashpoint for debate: Are the Cardinals being smart and disciplined by maximizing Romero’s value now, or are they over-correcting and moving on from a key bullpen piece too soon, just when they might be ready to turn the corner again? Some fans will argue you cannot constantly trade away your best relievers and expect to build a winning culture. Others will counter that hanging onto veterans during a reset is exactly how you get stuck in the middle—never bad enough to fully rebuild, never good enough to truly contend.
What do you think: should St. Louis cash in on JoJo Romero while the market is hot, or is trading one of their most dependable late-inning arms a mistake they’ll regret if they bounce back sooner than expected? Do you agree with a long-term, prospect-focused approach, or would you rather see the team keep more established pieces and push for wins right now? Share where you stand—and don’t be afraid to disagree sharply. This is exactly the kind of move that can divide a fanbase.
