The Cardinals officially sent Helsley to the Mets by the trade deadline, getting back three prospects: shortstop Jesús Báez and right‐handers Nate Dohm and Frank Elissalt.That move makes clear they’re looking ahead, especially toward 2026, when they’ll need someone reliable in the ninth.
Among internal options, Gordon Graceffo has drawn a fair amount of buzz. He’s been used in save opportunities already, and his stuff looks good — upper‐90s fastball, good metrics. Riley O’Brien is also emerging as a “dark horse.” He hasn’t allowed a run over several recent appearances and has struck out batters at a strong clip, though his control is something he’ll want to keep working on.
Another interesting name is rookie Andre Granillo, who in a small sample at the Major League level has looked sharp. He’s got closing experience in the minors, and though moving him directly into late‐game high pressure is a bit of a risk, he has the pedigree to be considered. Phil Maton is also in the mix. As a veteran, he gives the team a lower‐cost, lower‐risk option. His numbers in setup and high leverage have been good this season, so Maton could serve as a bridge or fallback if the younger arms need more seasoning.

Beyond internal candidates, the Cardinals may look externally. There has been speculation about targeting established closers or bullpen aces, either via trade or free agency, to shore things up while the younger players develop.
Managerial strategy seems to be trending toward flexibility rather than rushing to name a permanent closer. There are reports the Cardinals may adopt a closer‐by‐committee model in the near term, giving different relievers opportunities in the ninth while they evaluate who handles the pressure, consistency, and health best.
In short, while Helsley’s departure leaves a big hole, the Cardinals appear to have several promising internal arms and are keeping outside options open. The decision for 2026 is likely to come down to performance under pressure, health, and cost—especially if the team is leaning toward developing young players rather than committing big money in free agency.
