Blue Jays vs Mariners Predictions – Odds, Props & Top Picks

Toronto is a -130 moneyline favorite at home in Game 7.

  • Runline: Blue Jays -1.5 (_155)
  • Game Total: 7.5 Runs

Shane Bieber already dominated this exact Mariners lineup in Game 3 – six innings, two earned runs, eight strikeouts in Toronto’s 13-4 blowout. The 2020 Cy Young winner posted a 3.57 ERA across seven starts in 2025 after returning from Tommy John surgery, with a ridiculous 5.29 K/BB ratio.

His command is back, his stuff is sharp, and he’s seen this Seattle roster once already and carved them up.

George Kirby, meanwhile, is coming off the worst start of his postseason career. In that same Game 3, he got absolutely torched – four innings, eight earned runs, three home runs allowed.

Vladimir Guerrero Jr., George Springer, and Andrés Giménez all took him deep. His ALCS ERA sits at 7.07 heading into tonight.

The Mariners are asking a 27-year-old to bounce back from getting shelled, on the road, in the most pressure-packed environment of his life

Vladimir Guerrero Jr. Props

Look, I’ve been doing this long enough to know when someone’s locked in, and Vlad Jr. is operating on another plane of existence.

Blue Jays vs Mariners Props - Vlad Guerrero

The man is hitting .462 with six home runs through eight postseason games. Six homers leads all of MLB in the playoffs. He’s struck out just twice in 47 plate appearances – that’s not a typo, TWO strikeouts all postseason.

You can bet a ton of Guerrero props on Underdog.

Josh Naylor Player Props

I’m fine with betting on Vlad, but I love attacking this 6.5 Fantasy Points number for Naylor.

Bieber was very good earlier in the series, but he hasn’t been fantastic against left-handed hitters, striking out just 17% of them in the last 30 days.

This number is appealing for Naylor beacause of his new-found ability to steal bases. He is no longer just solely reliant on power to clear props and fantasy point projections.

Blue Jays vs Mariners Game 7 Prediction

This series had so many twists and turns. I’m siding with Toronto at home, and it’s mostly because of Bieber.

This is the exact moment why Toronto acquired Bieber and was fine with stashing him away until he was healthy again.

The veteran has allowed no more than two earned runs in any of his last six starts dating back to early September.
