The St. Louis Cardinals’ strategy for the upcoming trade deadline remains uncertain. President of Baseball Operations John Mozeliak is taking a “wait-and-see” approach, hoping the next month will clarify whether the team is a true contender or simply treading water. That outcome will shape their direction—whether to buy, sell, or stand pat.
Meanwhile, teams like the Dodgers, Yankees, Mets, and Tigers are already gearing up for the trade market as they position themselves for postseason pushes. This has sparked some intriguing trade chatter.
In early June, ESPN’s Jeff Passan released his preliminary 2025 MLB trade deadline preview. He identified closer Ryan Helsley as the Cardinals player most likely to be moved. However, if the team continues to win, they may hold onto the two-time All-Star. Should they trade him, though, they’ll need someone to take over his role—and a few names are in the mix.
Phil Maton (RHP)
Maton has quietly been a major asset this year. Signed late in the offseason to a one-year, $2 million deal, he’s delivered a 1.84 ERA over 29.1 innings, with 39 strikeouts and a 1.091 WHIP. He’s served well in high-pressure spots and even has two saves this season. Though he’s never been a full-time closer, Maton’s track record in leverage situations makes him a strong candidate to step into that role. The Cardinals could even consider trading Maton instead of Helsley, given his strong numbers and affordable contract.
Andre Granillo (RHP)
Rookie Andre Granillo has impressed in his short time with the big-league club. Over 6.2 innings, he holds a 1.35 ERA with a 1-0 record and a save—both earned in a doubleheader against the White Sox. Granillo has a background as a closer in the minors, racking up 30 saves. While he may experience growing pains in the closer role, he has the credentials to eventually thrive there.
Gordon Graceffo (RHP)
Graceffo spent the offseason refining his mechanics with Tread Athletics and expressed willingness to help the team in any role. Though previously a starter in the minors, he’s worked solely out of the bullpen this year. Through 17.2 innings, he has a 6.62 ERA with 15 strikeouts and only four walks. Despite inconsistent results and a high number of hits allowed, he’s shown flashes of potential. If he can recapture his minor-league strikeout form (9.1 K/9), he could emerge as a closing option if Helsley is moved.
