The Mariners and Blue Jays will battle it out in ALCS Game 7 to see who will take on the Dodgers in the World Series. Tonight's Game 7 is set for 8:08 p.m. ET on Monday and it will air on FOX and FS1.
Both teams will have one of their better starting pitchers on the mound when Mariners SP George Kirby faces Blue Jays SP Shane Bieber. Let’s discuss what that could mean for our Mariners vs. Blue Jays prediction and PrizePicks picks for Game 7 tonight.

Mariners vs. Blue Jays Prediction for Game 7 Tonight
The Blue Jays forced Game 7 by winning at home Sunday in Game 6. Blue Jays SP Trey Yesavage logged 5 2/3 innings, so the Blue Jays only used two relief pitchers. One of them was their closer Jeff Hoffman, who threw 35 pitches over two innings.
The Mariners used three relieves in the game, though most should be available out of the pen tonight. The Mariners also could turn to ace Bryan Woo out of the bullpen, as he's only pitched two innings so far in this series, both in the Game 5 win.
Mariners Preview vs. Blue Jays
While the Mariners won the first two games of the series in Toronto, they weren’t a great road team during the regular season. They went 51-30 at home, but just 39-42 on the road. That marked their second straight season with a losing record on the road.
The Mariners are batting .212 in the postseason (fifth among all teams), though 3B Eugenio Suarez came back to life with two home runs in Game 5, now batting just .209 in the postseason.
Blue Jays Preview vs. Mariners
The Blue Jays went 54-27 at home during the regular season. The only team to finish with a better record at home was the Phillies, who went 55-26. The Blue Jays continue to do a great job of making contact, striking out a total of just 58 times across 10 playoff games.
The Blue Jays lead the MLB in batting average in the postseason by a wide margin, with a .294 average, plus a postseason-leading 19 home runs.
