The winner of the National League Championship Series could determine if Major League Baseball is played in 2027.

This might sound far-fetched. It is not. What looks like a best-of-seven baseball series, which starts Monday as the Milwaukee Brewers host the Los Angeles Dodgers in Game 1, will play out as a proxy of the coming labor war between MLB and the MLB Players Association.

Owners across the game want a salary cap — and if the Dodgers, with their record $500 million-plus payroll, win back-to-back World Series, it would only embolden the league’s push to regulate salaries. The Brewers, consistently a bottom-third payroll team, emerging triumphant would serve as the latest evidence that winners can germinate even in the game’s smallest markets and that the failures of other low-revenue teams have less to do with spending than execution.

The truth, of course, exists somewhere in between. But in between is not where the two parties stake out their negotiating positions in what many expect to be a brutal fight to determine the future of the game’s economics. And that is why whoever comes out victorious likely will be used as a cudgel when formal negotiations begin next spring for a collective bargaining agreement that expires Dec. 1, 2026.

If it’s the Dodgers, MLB owners — who already were vocal publicly and even more so privately about Los Angeles spending as much as the bottom six teams in payroll combined this year — will likely cry foul even louder. Already, MLB is expected to lock out players upon the agreement’s expiration. Back-to-back championships by the Dodgers could embolden MLB and add to a chorus of fans who see a cap as a panacea for the plague of big-money teams monopolizing championships over the past decade.

Such a scenario would not scare the union off its half-century-old anti-cap stance. The MLBPA has no intention of negotiating if a cap remains on the table, and considering MLB was on the cusp of losing games in 2022 because of a negotiation that didn’t include a cap, players already have spoken among themselves about how to weather missing time in 2027. Certainly, the Brewers winning wouldn’t ensure avoiding that, but if in any argument about the necessity of a cap, the union can counter that the juggernaut Dodgers lost to a team of self-proclaimed Average Joes with a payroll a quarter of the size, it reinforces the point that team-building acumen can exist regardless of financial might.

The Brewers have joined the Tampa Bay Rays and Cleveland Guardians as vanguards of low-revenue success in this decade. Over the past eight years, Milwaukee has won five NL Central titles and made the playoffs seven times. At 97-65 this year, the Brewers owned the best record in baseball. And they did so with a unique blend of players.

Of the 26 players on Milwaukee’s NLCS roster, 15 came via trade, according to ESPN Research, including a majority of its best players (slugger Christian Yelich, catcher William Contreras, ace Freddy Peralta and Trevor Megill, the closer for most of the season). The Brewers drafted four (Brice Turang, Jacob Misiorowski, Sal Frelick and Aaron Ashby, all major contributors), signed three as minor league free agents, brought in two via international amateur free agency (their best player, Jackson Chourio, and closer Abner Uribe) and snagged one in the minor league portion of the offseason Rule 5 draft.

That leaves one major league free agent. One. And it was left-hander Jose Quintana, who signed a one-year, $4 million deal in March.

Think about that: The MLBPA, which has fought for free agency since its inception, would be heralding a team that does not spend on free agents. Strange bedfellows, yes, but it strengthens the union’s position: If the current system is beyond repair because of money, how did a team that doesn’t spend win a championship?

The Dodgers, on the other hand, are not nearly as free-agent-heavy as might be assumed. They’ve acquired the most players via trade, too, though it’s only nine, and several of them — from Mookie Betts to Tyler Glasnow to Tommy Edman to Alex Vesia — play a significant role on the team. Los Angeles signed five major league free agents (including Shohei Ohtani, Freddie Freeman and Blake Snell), plus two professional international free agents (Yoshinobu Yamamoto and Hyeseong Kim), two amateur international free agents (Roki Sasaki and Andy Pages) and two minor league free agents (Max Muncy and Justin Dean). They drafted five of their players — one more than the Brewers, whose development system is regarded as one of baseball’s best — and rounded out their roster with Jack Dreyer, an undrafted free agent.

Dreyer highlights what the Dodgers and Brewers do exceptionally well: extract talent from players through systems that value a combination of scouting, analytics and superior coaching. It doesn’t matter whether you spend half a billion dollars or the $115 million or so currently on the Brewers’ books. If you can become an organization that gets the best out of players, winning will follow.

Perhaps if they weren’t so terminally parked at opposite ends of the continuum, the league and union could agree that staking an argument around one playoff series is foolhardy. Both sides should understand that, in the grand scheme, a seven-game series says very little, particularly when it comes to the complicated economic system of 30 billion-dollar corporations competing in the same space.

But this battle is as much about narrative as it is reality, and if MLB is going to push for a salary cap, it needs as much evidence as possible, and the Dodgers becoming the first team in a quarter-century to win back-to-back World Series would provide another nugget on top of the reams the league already cites. The last team to do that was the New York Yankees — and the competitive-balance tax, the proto-cap that currently penalizes high-spending teams, came into existence specifically to check what other owners believed the Yankees’ runaway spending.

The Dodgers are the new Yankees, more moneyed and willing to spend than anyone. They’ve won the NL West 12 of the past 13 years and captured championships in 2020 and 2024. And despite their seeming inevitability, baseball is not suffering in most areas important to the league. Television ratings are up. Attendance has increased. The implementation of the pitch clock before the 2024 season modernized the game and is now almost universally beloved. The addition of an automated ball-strike challenge system next year will only add to the game’s appeal.

This NLCS is baseball at its best. A well-oiled machine of superstars, peaking at the right time, looking to become baseball’s first back-to-back champions since 2000, against a team that plays a delightful brand of baseball, is wildly likable and always seems to succeed, too. The Brewers haven’t won a championship yet — not just in this recent run of excellence but in their 57-year history — and derailing the Dodgers en route to doing so would make the tale of triumph that much greater.

And, yes, despite the higher win total, the Brewers enter this series as the underdog, and it’s a fair designation. Even if they swept the Dodgers in the six games they played in July. Even if their bullpen is filled with fireballing nastiness. Even if they have whacked as many home runs this postseason as Los Angeles, despite the Dodgers hitting 78 more during the regular season.

There will be a lot of great baseball played in Milwaukee and Los Angeles over the next week-plus, fans’ cups running over with the sorts of matchups that make October the most special month of the year. Ohtani, Betts and Freeman trying to catch up to Misiorowski’s fastball and read his slider. Chourio, Contreras and Turang trying to solve Snell, Yamamoto, Glasnow and Ohtani. The Brewers’ terrifying bullpen, with five relievers throwing 97 mph-plus, against the team that hit high-octane fastballs better than anyone this year. The Dodgers trying to figure out if they can rely on any reliever other than Sasaki, and the Brewers, who were the fifth-toughest team to strike out this season, trying to get to Los Angeles’ bullpen with a barrage of balls in play.

While the baseball itself will be indisputable, this NLCS is bigger than the game. Its tentacles will reach into the future, with an unwitting but undeniable place in something far more consequential. It’s just one series, yes. But it’s so much more.

TORONTO — Bryce Miller overcame a shaky first inning and gave the tired Seattle Mariners the start they needed in the AL Championship Series opener.

Miller pitched six sharp innings, Jorge Polanco hit a go-ahead single in the sixth and the Mariners beat the Toronto Blue Jays 3-1 Sunday night as they returned to the ALCS for the first time in 24 years.

“The year, personally, didn’t go how I had planned and how I had hoped for but we’re in the ALCS and I got to go out there and set the tone,” Miller said. “I felt great.”

Seattle slugger Cal Raleigh added a tying solo home run, his second homer of the postseason after leading the major leagues with 60 in the regular season.

“That was a big lift,” Mariners manager Dan Wilson said of Raleigh’s drive in a two-run sixth.

George Springer homered on the first pitch from Miller, who then escaped a two-on jam in a 27-pitch first inning.

Anthony Santander singled in the second for Toronto’s only other hit, and Seattle pitchers retired 23 of the Blue Jays’ final 24 batters. Miller, Gabe Speier, Matt Brash and Andres Munoz combined to throw just 100 pitches less than 48 hours after the Mariners needed 209 pitches to outlast Detroit over 15 innings.

“The job Bryce Miller did tonight was phenomenal,” Mariners manager Dan Wilson said. “After that first inning, he went into a different gear. You saw him getting ahead, using all his stuff.”

Miller, the winner, struck out three and walked three in six innings, throwing 76 pitches. The three relievers each had eight-pitch, 1-2-3 innings, with Muñoz getting the save.

Raleigh tied the score in the sixth with his ninth homer in 14 games at Rogers Centre. Kevin Gausman had held batters to 0 for 16 on splitters in the postseason before Raleigh’s homer.

“I was trying to get bat on ball, really just trying to put something in play,” Raleigh said, wearing a T-shirt with the words: “JOB’S NOT FINISHED.” “I didn’t want to punch out again.”

Polanco hit a go-ahead single later in the inning and added an RBI single in the eighth.

“He’s been huge from both sides of the plate,” Raleigh said .

AL West champion Seattle traveled to AL East winner Toronto on Saturday after a 3-2 home victory over the Tigers on Friday to win the Division Series, the longest winner-take-all game in Major League Baseball history.

Seattle, the only MLB team to never host a World Series game, held Toronto to two hits after the Blue Jays had 50 hits and 34 runs in their four-game Division Series against the New York Yankees.

“We’re a really good offense,” Blue Jays manager John Schneider said. “Today it just didn’t work out.”

Toronto’s Vladimir Guerrero Jr. went 9 for 17 with three homers and nine RBIs against the Yankees but finished 0 for 4 Sunday with three groundouts.

“This is going to be a hard-fought series, man,” Schneider said. “These guys will be ready for it.”

Springer’s 21st postseason home run broke a tie with the Yankees’ Derek Jeter, moving him into sole possession of fifth place on the career list.

Raleigh’s homer was his fourth in 15 at-bats against Gausman, who took the loss.

“Up to that point, I’d been throwing the ball really well and had the game right there,” Gausman said. “This one’s on me.”

Gausman allowed two runs and three hits in 5⅔ innings.

“Great hitters capitalize on mistakes,” Schneider said. “That split from Kev just kind of leaked back over the middle a little bit.”

Raleigh hit a one-out single off Gausman in the first and advanced to third on Julio Rodríguez’s base hit but was thrown out at the plate by third baseman Addison Barger on Polanco’s grounder.

Polanco, who had the game-ending single Friday, singled against Brendon Little to drive in Rodríguez, who had chased Gausman with a two-out walk.

Polanco added another RBI single against Seranthony Dominguez.

Eugenio Suarez doubled off the top of the right-field wall against Louis Varland in the seventh. The 395-foot drive would have been a homer in 15 of 30 big league ballparks, including Seattle.

Toronto outfielder Nathan Lukes left in the fourth inning. Lukes bruised his right knee when he fouled a pitch off it in the first inning. Schneider said X-rays were negative and said Lukes might return Monday.

TORONTO — The Blue Jays‘ George Springer homered on the first pitch from Seattle‘s Bryce Miller in the American League Championship Series opener Sunday, moving past the New York Yankees‘ Derek Jeter into sole possession of fifth place on the career list with his 21st postseason home run.

Springer’s 385-foot drive to right field on a fastball at the outside corner put Toronto ahead with the first postseason leadoff home run in Blue Jays history. Springer has 63 leadoff homers in the regular season, second to Rickey Henderson’s record 81.

Manny Ramirez hit a record 29 postseason homers and is trailed by Jose Altuve (27), Kyle Schwarber (23) and Bernie Williams (22).

However, also in the first inning, Blue Jays outfielder Nathan Lukes fouled a ball off his right knee, falling in pain. He stayed in the game and drew a 12-pitch walk, then flied out leading off the third and was replaced by Myles Straw for the start of the fourth.

The team said he bruised his knee and was being further evaluated.

Lukes went 4-for-12 with five RBIs in Toronto’s division series win over the Yankees, including a key two-run single in the Game 4 clincher. He also made a diving catch in Toronto’s Game 1 win.
