The St. Louis Cardinals remain one of MLB’s most intriguing teams. Despite boasting a talented roster, they’ve consistently fallen short in recent seasons and have once again started the current campaign slowly. As a result, many believe they could be aggressive at the upcoming MLB trade deadline. With several valuable assets on the roster, St. Louis may become a seller — though it’s unclear if they’ll make any major moves.
One player drawing particular attention is reliever. According to Tim Kelly of Bleacher Report, He was recently named among the top-10 most likely trade candidates. As he’s in the final year of his contract, the Cardinals could look to move him if an extension isn’t in the works — especially if they fall further out of contention.

Helsley is coming off a stellar 2024 season in which he won the Trevor Hoffman Award as the NL’s best reliever, finishing with a 2.04 ERA and an MLB-leading 49 saves. He’s continued to pitch well this year, posting a 2.57 ERA through seven games. Given the high demand for reliable bullpen arms at the deadline, Helsley could fetch a significant return — possibly two top-10 prospects from a contender’s farm system.
Ultimately, whether the Cardinals decide to deal him may hinge on how they’re positioned in the standings as the deadline approaches.
