As the St. Louis Cardinals anticipate championship contention several years into the future, the team parted ways with some veteran pieces at the latest trade deadline in exchange for prospect talent.

That included a pair of players who went on to win the World Series championship after joining the Milwaukee Brewers, including high-leverage reliever JoJo Romero.

Now the Cardinals are reportedly interested in reuniting with Romero and have maintained a specific clubhouse feature that appears to reinforce that interest.

“Fresh of a World Series championship with Milwaukee, Romero reaches free agency for the first time in his career, and the Cardinals are at least interested in discussing a reunion,” Derrick Goold reported for the St. Louis Post-Dispatch. “Plus, the Cardinals kept the locker of snacks he curated for the team intact.”

St Louis Cardinals Could Re-Sign JoJo Romero After Milwaukee Brewers World Series Run

Romero’s potential availability presents an interesting opportunity for St. Louis, particularly given his previous contributions to the organization’s bullpen.

The left-handed reliever joined the Cardinals in 2022 after beginning his major league career with the Philadelphia Phillies and gradually established himself as a dependable late-inning option.

His best season in St. Louis came in 2025, when he recorded a 2.07 ERA across 65 appearances, collecting eight saves. That performance helped establish him as a valuable piece of the Cardinals’ relief corps before the organization decided to move him at the 2026 trade deadline.

“With free agency looming, the Cardinals sent Romero and Dustin May to the Brewers for outfield prospects Alexander Frias and Josiah Ragsdale,” Charlie Wright recalled for MLB Trade Rumors. “The swap worked out well for both sides. The addition of Romero gave (Brewers) manager Pat Murphy another southpaw alongside Aaron Ashby in the later innings. Romero was scored upon in just one of seven playoff outings.”

St Louis Cardinals Reunion Could Make Sense For World Series Champion Pitcher

Romero’s postseason performance only strengthened his appeal as a potential bullpen addition for virtually any team. He finished Milwaukee’s championship run with a 1.13 ERA across seven appearances and eight innings.

For St. Louis, bringing him back could provide some much-needed familiarity and experience while giving its bullpen another established left-handed option. Romero also has a demonstrated track record with the organization, making a reunion potentially easier to envision than pursuing an unfamiliar free agent.

Still, reported interest does not necessarily mean an agreement is imminent. The Cardinals will have to weigh their bullpen needs, available resources and longer-term roster priorities before deciding whether to pursue their former reliever.
