Game 7 MLB Best Bets and Predictions for Today October 20, 2025

For the first time in two years we have a Game Seven in the MLB postseason. It's history for the Seattle Mariners, playing in its first Game Seven.

The Toronto Blue Jays are slightly favored in a winner-take-all game to be played et the Rogers Centre. This is the fourth time such a game has been played here. You'll be able to watch it on Fox on Monday evening at 8:08 PM ET.

This game is a rematch of Game Three from last Wednesday: Shane Bieber for the Jays and George Kirby on the bump for the Mariners. The first time these two met, Bieber was victorious as Toronto won 13-4.

Oddsmakers list Toronto at -122 and Seattle at +104. So far this series, the road team is 4-2. The M's have already shown they can win in Canada, taking Game One and Game Two at this ballpark.

My picks for Game Seven are both game props and player props. So far in the 2025 MLB postseason, I'm up a modest $170, or 1.5 units.

Mariners at Blue Jays: Player Prop Bets

The Blue Jays are going to come out aggressively against Kirby, a pitcher they lit up for eight runs last week in Game Three. I expect the TOR lineup to focus on contact and sending the ball the opposite way. That means few strikeouts, and possibly an early exit for Kirby, who must be on a short leash.

For that reasoning, I like Kirby under on K's in Game 7 vs Toronto.

For my second player prop wager, I am going at half a unit on a surprise power threat this October: Blue Jays second baseman Andrés Giménez. The Gold Glover has five hits this series, and two of them have been home runs.

If Andrés Giménez hits a home run tonight on our $50 wager, we win $600, including our stake. CHA-CHING, baseball fans.

• BET: Andrés Giménez To Hit a Home Run, +1000
• BET: George Kirby Under 3.5 Strikeouts, +116

Seattle vs Toronto: Game Prop Bets

For my first game prop, I turn to Top Of The First Odds. For this wager, I'm laying down half a unit ($50) on at least one extra-base hit in the top of the first. That means Seattle needs to produce a double, triple, or home run. If so, I win $105 plus my stake.

Runs can be scarce in a Game Seven. Often, pitchers have the edge in must-win games. Tonight, if the game is tied at the conclusion of the first inning, my game prop bet of $145 will win $100 plus my stake.

Nice thing: if the game is 1-1 after one inning, this bet wins. Or 0-0. If it's 9-9 after one inning, I win. Any tie, no matter the score, is a winner.

• BET: Extra Base Hit in Top of First, +210
• BET: Tie After One Inning, -145

Seattle Mariners at Toronto Blue Jays Prediction

Almost anything is possible in a Game 7. Just the phrase "Game 7" sends sports fans into a state of anxious excitement. Famous Game 7 moments in baseball are centered around heroes of the game: Johnny Podres, Bill Mazeroski, Bob Gibson, Willie Stargell, Jack Morris, Luis Gonzalez, Howie Kendrick, and more.

Who will be the hero tonight in Toronto? This is the second Game 7 ever played on Canadian soil. The first was Game Seven of the 1985 ALCS, which the Blue Jays lost to the Royals, almost exactly 40 years ago.

I like Bieber over Kirby to pitch the better game. In a Game 7, both managers will have a quick hook. But I trust John Schneider to use his bullpen better than Dan Wilson. Maybe too many foul balls clanged off Wilson's helmet and catcher's mask during his playing career, because he is making puzzling decisions with his staff this postseason.

Game Sevens often hinge on the play of superstars. The most super of stars in this series is Vladimir Guerrero Jr. The second-generation slugger is hitting .409 with a .955 SLG in the ALCS.

For a straight non-betting advice prediction, I like Toronto to win this game, 5-4.
