BREAKING: The 2025 American League Championship Series is officially set to ignite this Sunday, October 15, 2025, at Rogers Centre in Toronto. The No. 1 seed Toronto Blue Jays will face off against the No. 2 seed Seattle Mariners, with a coveted trip to the World Series on the line.
UPDATE: The Mariners clinched their spot after a nail-biting victory over the Detroit Tigers in Game 5 of the ALDS on Friday night, while the Blue Jays triumphed over their AL East rivals, the New York Yankees, to secure their place in the ALCS.
This highly anticipated matchup marks the first time these two teams, both born from the 1977 MLB expansion, will face such high stakes in the postseason. The Blue Jays haven’t claimed a championship in 31 years, and the Mariners are in pursuit of their first title ever.
TEAM ODDS: According to advanced simulations, Toronto has a 55.1% chance to advance, while Seattle trails closely with a 44.9% probability. Both teams have shown stellar performances, with the Blue Jays boasting a powerful lineup highlighted by Vladimir Guerrero Jr., who has shone brightly this postseason.
The Blue Jays’ offense has been relentless, averaging an impressive number of runs per game. Guerrero has been joined by teammates like Daulton Varsho and Ernie Clement, who have all contributed significantly during the ALDS. They dominated at home, scoring 23 runs in two games against the Yankees. Meanwhile, the Mariners have relied heavily on their starting rotation, with pitchers like George Kirby and Luis Castillo leading the charge.
KEY MATCHUPS: Both teams are looking to leverage their strengths—Seattle’s potent starting rotation against Toronto’s explosive batting lineup. The Mariners have seen success at home, posting a 3.28 ERA in their home games this season. However, the Blue Jays have shown they can score freely, even in challenging environments.
As the series approaches, the big question arises: Who will be the X-factor for each team? For Toronto, rookie sensation Trey Yesavage could make history with his unique pitching style. His outstanding performance against the Yankees has positioned him as a key player to watch. For Seattle, Randy Arozarena needs to ignite the offense after a slow start.
WHAT’S NEXT: The series kicks off with Game 1 at Rogers Centre, and anticipation is building. Fans and analysts alike are eager to see if the Mariners can overcome the Blue Jays’ home-field advantage and if Toronto can maintain their postseason momentum.
