The American League Championship Series is down to Game 7. The Mariners vs Blue Jays tonight in Toronto will decide which team will face the defending champion Dodgers in the World Series.

The Blue Jays forced Game 7 with a 6-2 victory over the Seattle Mariners on Sunday night. Vladimir Guerrero Jr. continued his remarkable postseason performance with his sixth home run of the playoffs, while rookie pitcher Trey Yesavage dominated through 5â…” innings, recording seven strikeouts. Seattle’s struggles were compounded by multiple errors throughout the game.

Tonight’s winner-take-all showdown will mark only the second time in franchise history that the Blue Jays have reached a Game 7 in the ALCS — their previous appearance came in 1985, when they fell to the Kansas City Royals. The Mariners will attempt to reach their first World Series.

Whichever team survives will face the Dodgers, who became the first defending champion to reach the World Series in 16 years. No defending champion had reached the World Series since the 2009 Philadelphia Phillies. No team has won consecutive titles since the 1998-2000 New York Yankees took three in a row.

Baseball bettors can redeem MLB betting promos using the leading sports betting apps for all of the MLB postseason action. We’re also providing odds for each game of the playoffs, all the way through the 2025 World Series, and odds on which club will win the Fall Classic.

For much of the 2025 season, the defending World Series champion Los Angeles Dodgers were the heavy favorite to repeat, anchoring the top of the odds board. But as the season wound down, they hit some turbulence in their play, and that has opened the door for more teams.

With the Philadelphia Phillies and New York Yankees eliminated, the Dodgers are now the preferred betting choice, according to the leading online sportsbooks.
