Mariners vs. Blue Jays ALCS Game 1: Date, Time & Lineups

Blue Jays and Mariners Set to Clash in Unexpected ALCS Matchup

TORONTO — The Blue Jays and Mariners will meet in the American League Championship Series, the matchup no one saw coming when the season began.

The Mariners advanced late Friday night wiht a 3-2 win over the tigers in a postseason game for the ages, a 15-inning marathon they’ll be talking about in Seattle for years. Jorge Polanco was the long-awaited hero in Game 5 of the American League Division Series, but outside of Mariners fans, few people enjoyed that game more than the Blue Jays.

Toronto watched it all unfold in as Seattle burned thru its bullpen, including starters Logan Gilbert and Luis Castillo after George Kirby gave them five-plus excellent innings earlier in the night. Just as the Blue Jays got to kick their feet up with a bye to the ALDS as the No. 1 seed in the American League, they’ll once again have the freshest pitching staff and all the time they need to set their rotation against an opponent who is scrambling into town. There’s no denying the value of momentum in October, though, and the Mariners are riding a tidal wave of it.

This will be the mariners’ first trip to the ALCS since 2001 and the Blue Jays’ first since 2016, signalling a shift in the power structure of the American League. The Mariners are still seeking their first World Series and the Blue Jays their first since 1993, when they whent back to back.

These two teams have been forever tied since coming into the league as expansion franchises in 1977. The Blue Jays’ annual trips to Seattle have long been the scene of a Canadian invasion, fans from western Canada pouring into T-Mobile Park to watch their team. There’s recent history, too, going back to the 2022 Wild Card Series in Toronto, when the Mariners erased an 8-1 deficit to eliminate the Blue Jays in their own house.

“We’ve been together on this,” Vladimir Guerrero Jr. said after clinching the ALDS. “And maybe some people don’t believe in the team through the year, but I always remind everyone that we have an entire country behind us that believe in us, and hopefully we can get the World Series back to Canada.”

The hours leading up to game 1 Sunday will help to set the scene, including some major updates expected on the potential returns of Mariners starter.

Miller Gets the Ball in ALCS Game 1 for Mariners

Seattle Mariners pitcher Logan Miller, the only healthy starting pitcher who didn’t appear in their thrilling Game 5 AL Division Series victory over Detroit, will start Game 1 of the American League Championship Series. Miller pitched 4 1/3 innings in Game 4 of the ALDS on Wednesday, throwing 55 pitches in a loss that necessitated the decisive Game 5. Consequently, he will be starting on just three days’ rest.

Potential Starting Lineups:

Blue Jays: The Blue Jays’ lineup hinges on the return of Bo Bichette. If he’s back, it’s likely as a designated hitter, which woudl shift George Springer to a corner outfield position.This would create a competition between Anthony Santander and Nathan Lukes for the remaining corner outfield spot. If Bichette remains unavailable,the Blue Jays are expected to field a lineup similar to those they used against right-handers Cam Schlittler and Luis Gil in the ALDS.

Mariners: Manager Dan Wilson has favored a consistent lineup, particularly since the Trade Deadline. This trend has continued into the playoffs, with adjustments made only based on the opposing pitcher’s handedness. Expect a lineup nearly identical to the one used against Detroit’s right-handed starters in the ALDS.

Bullpen Outlook:

Blue Jays: Following a strong bullpen performance that clinched their series against the yankees, the Blue Jays’ bullpen appears to be in good form. The roster spots of justin Bruihl and Tommy Nance could be affected by the potential availability of Max Scherzer and Ross Bassitt, but the core group is currently solid.

Louis Varland rebounded from a difficult Game 3, the left-handed relievers have been effective, and seranthony Domínguez offers proven playoff experience. However, much will depend on Jeff Hoffman, who had an uneven regular season (4.37 ERA, 33 saves) and allowed one run on two hits over 1 1/3 innings in his last appearance.
