Cardinals could reunite with World Series champion

After winning it all with the Milwaukee Brewers, relief pitcher JoJo Romero could return to the St. Louis Cardinals.

Derrick Goold of the St. Louis Post-Dispatch reported on Monday that the Cardinals are interested in reuniting with Romero. 

Meanwhile, Jeff Jones of The Belleville News-Democrat said Romero is also interested in running it back with the Cardinals.

Romero was part of the Brewers’ bullpen that dominated in the 2026 MLB playoffs. He joined Milwaukee in August, when the Cardinals traded him to the Brewers along with pitcher Dustin May in exchange for outfielders Alexander Frias and Josiah Ragsdale.

The Brewers trade for Romero paid off in a big way in the playoffs, where he allowed just an earned run on three hits through eight innings and across seven games. 

Romero stepped up in Game 4 of the National League Championship Series against the then-reigning World Series champion Los Angeles Dodgers, retiring superstars Shohei Ohtani, Mookie Betts and Freddie Freeman consecutively in the fifth inning. He went on to earn the pitching win as Milwaukee completed a sweep of the Dodgers.

The Cardinals seem to like what they saw from Romero after trading him. The reliever avoided arbitration in his final year of arbitration eligibility by signing a 1-year, $4.26 million contract with St. Louis in January.
