MLB September predictions: From best record to playoff races and more
Welcome to September! Five months into Major League Baseball’s 2025 season, a number of things seem to be settled — from a few divisions to some award races — but plenty of intrigue remains entering the homestretch.
Which of the current contenders will reach the playoffs? How will the closer division races play out? Which teams will secure first-round byes? And how many games will the Colorado Rockies lose?!
To discuss what the final month of the regular season might bring, we asked 16 ESPN baseball experts some of the game’s biggest questions, covering September and beyond, and to explain their answers. We also asked them to make bold predictions about what will happen over the final stretch.
Let’s get into it.
Which team will finish with the best record in baseball?
Milwaukee Brewers: 14
Detroit Tigers: 1
Los Angeles Dodgers: 1
What makes the Brewers the favorite to secure the majors’ best record? Besides the buffer the Brewers have built as we enter the final month of the regular season, there’s just nothing to suggest a falloff. They are on track to win about 100 games and their run differential supports that pace. The remaining schedule is friendly. And Milwaukee’s production has come from every position and category. It’s just a really complete team. — Bradford Doolittle
How many of the current 12 teams projected for the playoffs will be in the postseason field?
All 12: 15
11: 1
You have the Royals ousting the Mariners from the playoff field. Why do you think that will happen? The Kansas City Royals will make the playoffs. Crazy? Not so. They’ve played great in July and August. Vinnie Pasquantino is mashing home runs, Bobby Witt Jr. is red hot and the players they added at the trade deadline have chipped in to make this a good offense. The Royals also have a pretty easy schedule the rest of the way. But which team can they catch?
It might hinge on a three-game series at home against Seattle in mid-September. The Mariners have a recent history of falling just short of the postseason — including last year, when the Royals clinched a wild-card spot with 86 wins and the Mariners won 85 (the Mariners blew an 8-0 lead against Kansas City in June, which loomed large at the end of the season). Seattle has struggled on the road, so the aforementioned series can catapult the Royals back into the postseason. — David Schoenfield
Who will be the No. 1 seed in the AL: Toronto or Detroit?
Detroit Tigers: 14
Toronto Blue Jays: 2
The Tigers were the overwhelming choice. Why did you take them? For me, this was mostly a schedule play. The top seed, based on the standings, is likely to be the Tigers or the Blue Jays, with the Boston Red Sox, New York Yankees, Houston Astros and Seattle Mariners all within plausible striking distance. Toronto doesn’t have an easy series left. Detroit’s schedule isn’t nearly as rigorous. In a race this close, with teams this close in talent and production, little things like schedule luck often determine the outcome. — Jeff Passan
You were one of two voters to pick the Blue Jays. Why do you think they top Detroit? The Tigers are a wonderful story, but not so much since the All-Star break, as they have played .500 ball, struggled to score runs and their ERA is among the bottom 10 in baseball. The Blue Jays are peaking at the right time, scoring plenty of runs, and Max Scherzer and Shane Bieber make the rotation formidable. Frankly, all three AL East contenders are better than the current Tigers, and it should show in the final standings. — Eric Karabell
Assuming the Brewers get one, who will get the second bye in the NL?
Los Angeles Dodgers: 9
Philadelphia Phillies: 5
San Diego Padres: 2
Despite dealing with star players slumping and a mountain of injuries this season, the Dodgers are still the slight favorites for the No. 2 seed in a stacked NL. Explain why. Because those are the very reasons why the Dodgers firmly believe their best baseball is still ahead of them. Their bullpen will soon be as close to whole as it has been all season. The same can be said about the lineup. The rotation already is, and the four-man group they’ll put together in October will be scary if the starters remain healthy.
That’s a big “if,” considering the pitching ailments that have plagued them the last couple years. But at the end of the day, the Dodgers possess the most depth and talent in the sport. They feel as if they’re on the verge of truly showcasing it. — Alden Gonzalez
The Phillies also received a fair number of votes. What makes them your pick? The Phillies seem to be flying under the radar for a team that has spent most of the season on a 95-win pace. Maybe it’s the Zack Wheeler injury, maybe it’s their struggles against the New York Mets — or maybe it’s just that this is about what we’ve grown accustomed to seeing from Philly over the past few seasons.
But there is plenty to like here over the final month and into October as well. Even without Wheeler, the Phillies have the best Game 1 starter of any NL contender in Cristopher Sanchez. Kyle Schwarber has a real shot at Ryan Howard’s franchise home run record (58). They acquired the best reliever to move at the deadline in Jhoan Duran and filled their biggest hole by trading for outfielder Harrison Bader. Oh, and they currently hold that second spot in the NL — with a 1 1/2 game cushion over the Dodgers. — Dan Mullen
Will the Dodgers or Padres win the NL West?
Los Angeles Dodgers: 13
San Diego Padres: 3
The Dodgers were our voters’ overwhelming favorite to win the division. Why — and how — do you think San Diego can overtake L.A.? More than any other team, I think the Dodgers look at their seasons from 30,000 feet, rather than succumbing to the concerns of the moment. They demonstrate this every year with their handling of pitching injuries — they essentially rest veteran starters through long stretches of the season, rather than push them in May and June, in order to do what they can to ensure that the players will be relatively fresh in October. This is why we’ve seen such a deliberate ramp-up with Shohei Ohtani.
That’s why I think the Padres will wind up winning the division. They bolstered their bullpen with Mason Miller at the trade deadline, and since then, it feels like they’ve been playing a series of Game 7s. And, let’s face it, San Diego is all-in in trying to win right now, with its top-heavy roster and the likes of Dylan Cease and Michael King headed for free agency in the fall. The Dodgers, on the other hand, won’t go to the whip in September in the same way. No matter how their own division plays out, they’ll make the playoffs and have a shot to repeat as World Series winners, while it feels as if San Diego is going to go all-out down the stretch to win the NL West.
Different pressures, different styles, different context. — Buster Olney
Who will win the AL West?
Houston Astros: 8
Seattle Mariners: 8
Make the case for the Astros: Picking Houston to win the West isn’t going out on much of a limb: They’re currently in first place, just got slugger Yordan Alvarez back from injury and simply have more pedigree than Seattle. The Mariners have a slightly easier schedule the rest of the way but their road woes are for real — and will likely prevent them from going on an extended run. Picking against the Astros would be the headline-scratching move. They’re the division champ once again. — Jesse Rogers
Make the case for the Mariners: The Mariners aren’t playing their best baseball, but they are healthy and within striking distance of the Astros for the division entering September. Their starting rotation is elite. The bullpen and offense should be better. Meanwhile, the Astros have recently gotten Yordan Alvarez back from injury, but they’re without Josh Hader and Isaac Paredes, among others. The division could come down to the three-game series between the two rivals in late September. — Jorge Castillo
How many games will the Rockies lose?
119: 1
118: 3
117: 1
116: 3
115: 3
114: 3
113: 1
112: 1
We got quite the breadth of answers to this question, but you were one of three to say 118 losses — our second-highest loss total. Why is that your prediction? The Rockies aren’t far removed from being on a modern record-setting pace for losses, and they’ve been especially awful against the current 12 teams in the playoff field: 9-50 (.153). They play 13 of their final 24 against that group, at a time when they’re increasingly leaning on younger and less experienced players. Their September isn’t going to be pretty. — Tristan Cockcroft
Make one bold prediction about the final stretch
Tim Kurkjian: Seattle Mariners catcher Cal Raleigh will finish the season with 60 home runs.
Matt Marrone: With most of the playoff field set — other than last-minute jockeying for seeds — all eyes will be on the Mariners over the final days of the season, as Raleigh sets a new AL home run record.
Kiley McDaniel: Between hitting and pitching, Shohei Ohtani catches Raleigh in total WAR.
Passan: Athletics first baseman Nick Kurtz will finish in the top five of AL MVP voting.
Karabell: The Phillies call up top pitching prospect Andrew Painter on Sept. 7 and he goes 3-0 with a 1.50 ERA.
Mullen: Nolan McLean will be the NL’s best pitcher not named Paul Skenes over the final month and take the mound in October — as the Mets’ Game 1 playoff starter.
Paul Hembekides: Boston’s Garrett Crochet will overtake Detroit’s Tarik Skubal and win the AL Cy Young Award.
Schoenfield: The Red Sox will catch the Blue Jays and win the AL East.
Gonzalez: Actually, the Yankees will win the AL East.
Cockcroft: Not only do the Yankees overtake Toronto for the division title, but they also grab a first-round bye, even if they can’t quite catch the Tigers for the No. 1 seed.
Olney: The Yankees have such a soft schedule in the final weeks that they wind up with the second-best record in the AL … but because Toronto holds on to win the division, New York is the No. 4 seed and faces Boston in the wild-card round.
Tim Keown: The Padres, with the easiest remaining schedule in baseball, will go 7-0 against the Colorado Rockies in September to win the NL West and take the second first-round bye spot.
Castillo: The Mets will overtake the Phillies and win the NL East.
Doolittle: If we started the playoffs tomorrow, the bracket would look exactly the same as it will after we’ve played out the season.
Voters: Dan Mullen, Liz Finny, Paul Hembekides, Jeff Passan, Eric Karabell, Alden Gonzalez, David Schoenfield, Tim Kurkjian, Kiley McDaniel, Tim Keown, Jorge Castillo, Matt Marrone, Bradford Doolittle, Jesse Rogers, Tristan Cockcroft, Buster Olney

The NCAA sent a letter to Kalshi, a company that offers prediction markets on college basketball and football, expressing its concern about the company’s “commitment to contest integrity and the protection of contest participants,” according to a copy of the letter obtained by ESPN.
In the letter, dated Oct. 30, NCAA chief legal officer Scott Bearby asked Kalshi how it monitors collegiate sports markets for integrity concerns and activity by prohibited customers, who it considers a prohibited customer, whether it will report integrity concerns to the NCAA and whether the company will cooperate with NCAA investigations.
“We welcome Kalshi’s stance on its efforts to protect the integrity of NCAA competitions and to reduce instances of abuse and harassment directed at student-athletes and other participants,” Bearby wrote.
The NCAA also asked if Kalshi would ban prediction markets similar to prop bets, which the company began offering this fall.
Prop betting markets, Bearby noted in the letter, heighten “the risk of integrity and harassment concerns.” In March last year, NCAA president Charlie Baker called for a ban on prop bets on college athletes in states with legal sports wagering.
The NCAA also asked Kalshi in the letter to review language on its website that the NCAA says implies a relationship between them.
“Kalshi has robust market integrity provisions required by our status as a federally licensed financial exchange,” a Kalshi spokesperson said in a statement to ESPN. “We value the NCAA’s feedback and are working on adjusting the language on our site. We are currently reviewing and addressing their additional requests.”
Prediction markets like Kalshi have emerged over the past year and are competing with traditional sportsbooks in the betting market. Kalshi is battling multiple lawsuits by state gambling regulators, who allege that the company is violating state laws by offering event contracts that mimic sports bets. Kalshi argues that it does not fall under state jurisdiction and is instead regulated by the Commodity Futures Trading Commission, a federal agency.
In March, Kalshi announced a partnership with IC360, an integrity monitor used by many collegiate and professional leagues.
The NCAA has faced an increasing number of alleged betting violations by players in recent years. In September, the NCAA announced that a Fresno State men’s basketball player had manipulated his performance for gambling purposes and conspired with two other players in a prop betting scheme. In total, the association has opened investigations into potential betting violations by approximately 30 current or former men’s basketball players.
CORAL GABLES, Fla. — Miami has asked the Atlantic Coast Conference for clarity on a number of officiating decisions made in its loss this past weekend to SMU, including a critical 15-yard penalty in the final moments of regulation.
Miami lost the game, 26-20. The Hurricanes, who were as high as No. 2 in the AP Top 25 last month, have dropped two of their last three games and are now ranked No. 18.
Hurricanes coach Mario Cristobal said Miami has not gotten an answer from the ACC. It’s unclear if any explanations will be coming.
“Certainly, we’re waiting what the response is, as well as on the roughing the passer one which we certainly don’t agree with,” Cristobal said Monday. “But at this point in time, the best we can do is turn it in and hope for a better result next time.”
The Hurricanes’ Marquise Lightfoot was called for unnecessary roughness against SMU quarterback Kevin Jennings with about a minute left in the fourth quarter, giving the Mustangs 15 yards and a first down. Miami had called time out just before the fourth-and-9 play was snapped, and the Hurricanes argued to no avail that Lightfoot did not hear the whistle.
Replays showed that Lightfoot, who did make contact with Jennings, tried to hold the SMU quarterback up after apparently realizing the play was dead.
That penalty gave SMU the ball on the Miami 37, and the Mustangs went on to kick an overtime-forcing field goal.
Miami also was incensed about how a pass interference flag that would have aided the Hurricanes was picked up, and how officials missed a Hurricanes receiver getting tackled in the end zone on a play that wound up as a Miami interception in overtime.
Miami was called for 12 penalties in the game for 96 yards, compared with four by SMU for 40 yards. The eight-penalty differential tied Miami’s biggest of the season; it had 13 penalties compared with five by Florida State when those teams played in Tallahassee last month.
