The Cardinals were supposed to be sellers — at least, that’s what the rest of the league thought.
Instead, St. Louis has turned into one of baseball’s biggest post-All-Star break surprises, hovering in the National League playoff mix and making opposing GMs sweat. Why? Because everyone assumed they’d be offloading veterans by now. But with the trade deadline days away, the front office may be changing its tone — or at least trying to walk a fine line between buying and selling. And at the center of it all is Nolan Arenado. Could he join the Detroit Tigers before the end of the month?

According to The Athletic’s Jim Bowden, the Detroit Tigers have emerged as a surprise suitor for the veteran third baseman. It’s a deal that could shock both leagues — but one that makes more sense the closer you look.
Arenado will not be traded to the Yankees. Here’s why.
Nolan Arenado to the Detroit Tigers?
Bowden reports that the Tigers could split time between Arenado and Zach McKinstry at third, giving the former All-Star some valuable rest before a potential playoff push. But the key detail? St. Louis would likely have to eat part of Arenado’s contract and potentially package in a reliever to make the numbers work.
Arenado also has a full no-trade clause, one that he has exercised already once this year. Meaning he’d need to sign off on any deal — including one to Detroit. And since he holds all the cards, there is no telling if a deal will be made even if the Cardinals and Tigers come to an agreement.
Still, there’s a path.
Bowden suggests that if the Cardinals are holding out for a right-handed-hitting outfielder, Jahmai Jones could be the answer. He’s shown flashes but is buried behind a loaded Detroit Tigers roster. Wenceel Perez could also be in play. Either way, the idea of flipping Arenado to Detroit isn’t just speculation — it’s rooted in roster logic for both sides.
For the Tigers, this is a “go for it” moment. They’re not a lock for October, but they’re in the thick of it. Every upgrade counts — and adding Arenado to that lineup (even in a semi-platoon role) could push them over the edge.
Cardinals at the Crossroads
For the Cardinals, it’s a tightrope. Stay competitive, or cash in. Rebuild, or retool. They’re just close enough to the Wild Card race to justify hanging on — but just inconsistent enough to justify bold moves. If Arenado brings back a controllable outfielder and frees up innings for young infielders, it might be a move that balances both goals.
Either way, the next few days are going to get interesting in St. Louis. And if Nolan Arenado is on the move? Don’t be shocked if the deal comes from a team no one saw coming.
