Blue Jays and Mariners Set to Face Off in American League Championship Series
As October baseball heats up, the Toronto Blue Jays and Seattle Mariners are preparing for what promises to be an electrifying American League Championship Series. Game 1 kicks off on Sunday, October 12, 2025, at 8:00 PM ET at Seattle’s T-Mobile Park, with FOX handling the broadcast duties. For fans unable to attend in person, Fubo is offering streaming options to catch all the action. This matchup features two division champions looking to take the next step toward World Series glory—the Blue Jays dominated the AL East with an impressive 94-68 record, while the Mariners topped the AL West at 90-72, setting the stage for what should be a compelling contest between well-matched opponents.
The Mariners’ path to the ALCS wasn’t without its challenges, as they survived a nail-biting Divisional Series against the Detroit Tigers. The series went the distance, with Seattle emerging victorious in the decisive Game 5 by a narrow 3-2 margin. The win highlighted the depth of Seattle’s roster, with contributions coming from throughout the lineup. Jorge Polanco, Mitch Garver, and Leo Rivas all came through with crucial RBIs that ultimately made the difference in a series where every run mattered. This hard-fought victory demonstrated the Mariners’ resilience and ability to perform under pressure—qualities that will serve them well as they face an even tougher opponent in the Championship Series.
Toronto’s journey through the Division Series featured less drama but no less impressive performance as they dispatched the perennial powerhouse New York Yankees in four games. The Blue Jays secured their spot in the ALCS with a confident 5-2 victory, powered by a balanced offensive attack. Nathan Lukes emerged as an unexpected hero with two RBIs, while established stars George Springer and Vladimir Guerrero Jr., along with Myles Straw, each contributed run-scoring hits. The Blue Jays’ ability to eliminate their division rivals relatively quickly allowed them additional rest and preparation time heading into the Championship Series—a potentially significant advantage as the postseason grind continues.
The Game 1 pitching matchup features a contrast in styles and seasons, with Toronto sending veteran ace Kevin Gausman to the mound against Seattle’s younger arm Bryce Miller. Gausman brings consistency and experience, having posted a 10-11 record with a solid 3.59 ERA during the regular season. More importantly, he’s elevated his game in October, boasting an impressive 1.59 ERA in his postseason appearances thus far. Miller’s regular season was more uneven, as evidenced by his 4-6 record and 5.68 ERA, but postseason baseball often follows its own logic. His 4.15 ERA in the playoffs represents an improvement over his regular season form, suggesting he may be finding his rhythm at just the right time. Both pitchers have recorded just two strikeouts each in postseason play, indicating they’ve relied more on inducing weak contact than overpowering hitters.
As the series unfolds, baseball fans can look forward to a complete broadcast package, with FOX handling Game 1, Game 2, and a potential Game 7, while FS1 will cover Games 3 through 6. This comprehensive coverage ensures viewers won’t miss a moment of what promises to be a captivating series between two hungry teams. The Blue Jays bring a powerful offense led by Guerrero Jr. and balanced pitching, while the Mariners counter with scrappy play and timely hitting that has carried them this far. With both teams feeling they have something to prove on the national stage, expect intensity from the first pitch to the final out as these clubs battle for the right to represent the American League in the World Series.
The storylines surrounding this series extend beyond just the current rosters. For Toronto, this represents their best chance at a World Series since their back-to-back championships in 1992 and 1993. The Mariners, meanwhile, carry the burden of baseball’s longest active playoff drought, which they finally broke through just a few seasons ago. Now they stand just four wins away from their first-ever World Series appearance in franchise history. The contrasting organizational trajectories add another layer of intrigue to an already compelling matchup. As players take the field Sunday night, they’ll be battling not just for themselves, but for cities and fan bases that have invested years of hope and passion into these teams. The stage is set for baseball drama at its finest, with legacies and a pennant hanging in the balance.
