September has a way of putting a young roster on the field under a brighter light. Five clubs are already out of the October picture, but each has given its clubhouse a reason to look beyond the final homestand and toward a more competitive 2027.
September clubs with a future in the dugout
SEO Title: Five MLB clubs showing signs of a breakout future
SEO Description: The Athletics, Cardinals, Marlins, Mets and Nationals are out of the playoff chase, but young talent and late-season progress offer real reasons for optimism.
The result
There is no pennant race to measure for the Athletics, Cardinals, Marlins, Mets or Nationals. The useful result is different: young players have claimed jobs, prospect pipelines have strengthened, and several clubs have found the core that can make a losing season matter less in the long view.
The 2014 Cubs remain a reminder of how quickly that can turn. Chicago still lost 89 games that year and had not finished over .500 since 2009, but posted a winning mark after Aug. 1. Anthony Rizzo, Jake Arrieta and Kyle Hendricks were already in place. Kris Bryant arrived the following season, the Cubs won 97 games and eliminated the Cardinals in the postseason before capturing the World Series in 2016.
Not every rebuilding team needs that kind of sprint to become relevant. Sometimes the first indication is simply a younger lineup beginning to look like it belongs.
Athletics
The A’s endured a brutal July and August, going 13-39, but they have steadied themselves with an 8-4 September. Earlier in the year, they even held first place in the AL West heading into Memorial Day weekend, an early sign that their offense could carry a club short on pitching.
Injuries knocked that lineup off course, which is also why there is optimism around the group. Nick Kurtz and Shea Langeliers give the club two All-Stars at the center of the order. Jacob Wilson, Tyler Soderstrom and Brent Rooker remain part of the mix, with Rooker the only one older than 30.
Lawrence Butler has put together a strong second half. Nineteen-year-old shortstop Leo De Vries, ranked as baseball’s No. 2 prospect despite a recent injury, adds another potential impact bat. If the A’s can keep that group on the field and bring in pitching, their approaching move to Las Vegas could arrive alongside a far more dangerous roster.
Cardinals
St. Louis spent this season trying to identify its next position-player core while replenishing pitching depth in the system. The pitching answer is not complete yet, although Liam Doyle, MLB’s No. 43 prospect, heads an encouraging group.
The lineup has offered clearer answers. Nolan Gorman may have slipped out of the club’s plans, and Iván Herrera’s season lost momentum, but three of the 13 Cardinals who made their major league debuts have made a strong case for everyday roles.
JJ Wetherholt has taken over at second base, established himself as a leadoff option and become one of baseball’s top defenders. The Cardinals have already extended him for nearly a decade. Joshua Báez made a debut that ranked among the most memorable in major league history, stumbled for a short stretch afterward, then regained his footing. He now looks capable of forming a formidable outfield pairing with Jordan Walker, who has also taken a step forward this season.
Catcher Leo Bernal has looked unusually polished from his first game, providing the organization with a possible long-term answer behind the plate in the years since Yadier Molina departed. Rainel Rodriguez, baseball’s No. 17 prospect, is another major piece, bringing some of the most impressive power potential in the Minor Leagues.
Marlins
Miami opened 2026 with an organizational reset, from calling pitches out of the dugout to reworking routine baseball practices. The first-half results were real: the Marlins reached the break seven games above .500 before a 12-game losing streak wiped away the momentum.
Even so, the roster has grown. Otto Lopez emerged, and the rotation has a meaningful base in Sandy Alcantara, Eury Pérez, Max Meyer and Tyler Phillips. Ryan Gusto and Janson Junk offer further options. No regular in the lineup is older than 28, giving Miami a young group in a difficult NL East.
The division will not get easier, but the Marlins’ new approach has produced enough progress to suggest the changes are taking hold.
Mets
The Mets did not get the season they expected, and their postseason hopes disappeared months ago. Since Aug. 4, however, they have gone 22-14, one of the better records in the National League during that stretch.
It is not a traditional rebuild for a club carrying expensive veterans, but the recent surge has been driven by young players. Outfielders Carson Benge and A.J. Ewing, along with right-hander Nolan McLean, have all emerged as National League Rookie of the Year candidates.
Alongside Juan Soto, those three have been among the Mets’ best players. They now look like durable parts of the club’s plans rather than short-term September stories. The front office also acquired Jefferson Rojas, the No. 75 prospect in baseball, at the Trade Deadline and retains the financial capacity to address other needs. A large setback may have opened the door to a steadier step forward.
Nationals
Washington’s offense may be the clearest signal among these five clubs. The Nationals rank third in MLB in runs scored, trailing only the Cubs, Brewers and Dodgers. More importantly, the production has come largely from players who should remain central to the next competitive Washington team.
James Wood, still only 23, owns a .918 OPS and has become the headliner. Keibert Ruiz, Daylen Lile and Dylan Crews have also shown improved signs. CJ Abrams has fully broken through, and Washington’s decision to retain him at the Trade Deadline after moving Luis Garcia Jr. and Curtis Mead for pitching suggests he is either part of the next push or a key element in an offseason pitching plan.
There is still substantial work to do on the mound, even with Cade Cavalli enjoying a breakout season. But Wood and Abrams now look like established stars, while 18-year-old shortstop Eli Willits, MLB’s No. 4 prospect, has reached Double-A after an excellent first full professional campaign.
For these clubs, the standings may not offer much comfort this September. The clubhouse, the lineup card and the farm reports tell a more useful story: the next good team may already be taking shape.
