The St. Louis Cardinals have reached the point in the season where the standings and the long view are pulling in different directions.
They open the second half of 2026 just one game out of the final National League wild card spot and five games above .500, a position that would tempt plenty of clubs into chasing the bracket. But St. Louis is still in rebuild mode, and that reality could force a harder, less glamorous choice at the trade deadline: selling instead of buying.
If the Cardinals go that route, the move that makes the most sense is dealing All-Star closer Riley O'Brien. O'Brien, who was in the midsummer classic on Tuesday, is tied for second in the National League in saves after a strong first half. He is also under team control through 2030, which gives him plenty of value on the trade market.
That kind of profile can bring back real talent, and for a team still trying to stock the system, that matters. The Cardinals are entertaining, sure, but they are not built to win a World Series this fall. Trading O'Brien while his value is high could land a solid prospect or two and help keep the rebuild moving in the right direction.
Relievers, of course, can turn volatile fast. That only adds to the case for moving O'Brien now, before the market shifts and before any dip in performance chips away at what he could return.
Chaim Bloom has already made the organization’s stance clear: no shortcuts. He wants the Cardinals to stay patient and stick to the proper timeline, even if that leads to difficult decisions that won’t sit well with everyone.
And the bigger picture still points the same way. The Cardinals are not a World Series contender as currently built.
Their farm system is in better shape than it was, but it still needs more work. Adding major league-ready pitching prospects could deepen that pipeline and help speed up the rebuilding process.
O'Brien is 31, and there’s no guarantee he’ll match this level of production in 2027 and beyond. That’s why he stands out as the Cardinals’ most logical deadline chip if they decide to sell. The next few weeks will show whether Bloom is ready to act on that logic.

Cardinals Just Lost A Veteran Arm In A Familiar Weak Spot
Bruce Zimmermanns brief run with the Cardinals ended almost as quickly as it began, with St. Louis designating the left-hander for assignment after his lone appearance on July 7. The move sent him off the 40-man roster and into the kind of churn that often follows a spot start or emergency call-up, and the club followed it up with a batch of other minor league transactions across the system.
For the Cardinals, the bigger issue is less about Zimmermann himself than the familiar shape of the depth chart behind him. Triple-A has become a holding pattern for arms the organization may need in a hurry, with Quinn Mathews, Brycen Mautz, Hunter Dobbins and others sitting in that pipeline as the club continues sorting through options. Zimmermanns exit only adds another reminder of how quickly that back-end pitching picture can change. [Read more 🡒]
Cardinals Fans May Not Be Ready For Jordan Walker's Price Tag
Jordan Walker is still early enough in his Cardinals tenure that the conversation around his next contract can feel distant, but the clock is already ticking toward a major decision. He is projected to reach free agency after the 2029 season, and if St. Louis decides it wants to keep him in place beyond that, the price is expected to reflect both his upside and the market for young star talent.
Derrick Goold of the St. Louis Post-Dispatch has pointed to the kind of money attached to the clubs biggest long-term commitments as a possible guide, which is exactly why this feels like more than routine roster planning. Cardinals president Bill DeWitt III has already said the team expects to work on more extensions, and Walker looks like the type of player who could force the front office to decide just how far it is willing to go.

Cardinals Suddenly Face Another Bullpen Decision They Could Regret
Scott Blewett has put the Cardinals in a familiar midseason bind, one that starts in Triple-A but quickly spills into the major league bullpen picture. The right-hander has spent the year at Memphis, where the results have been uneven, but the strikeout ability is still enough to keep him on the radar as St. Louis tries to sort through a relief group that never seems far from another shuffle.
For the Cardinals, the issue is less about whether Blewett can miss bats and more about whether they want to make room for him now. Keeping him would require a 40-man move, and with bullpen spots already under pressure, the front office has to weigh one arm against the rest of the relief mix. It is the kind of decision that can look minor in the moment and turn into a regret if the wrong pitcher gets squeezed out. [Read more 🡒]
