The stage is set for one of the most dramatic nights in baseball. After a week of back-and-forth battles, the American League crown comes down to one final game. The Blue Jays, once down 0-2, have clawed their way back to force a decisive Game 7 at home in front of a roaring Rogers Centre crowd.

The Mariners, after letting a golden opportunity slip away, now face the ultimate test of resilience. Everything, momentum, pressure, and pride, collides tonight in Toronto, where one team will punch its ticket to the World Series and the other will see its season end.

The Greatest Two Words in Sports

No, not Shohei Ohtani. Game 7.

After falling flat in Game 6, the Mariners allowed the Blue Jays to cruise to a 6-2 win and even the series. Toronto has the chance to complete their comeback after starting down 0-2. One win separates them from the World Series.

Why the focus on Toronto? Because I have a prop backing their offense once again, Blue Jays over 2 runs in the first five innings at $1.40.

Kirby vs. Toronto

The Blue Jays face Mariners right hander George Kirby, who has struggled on the road all season. He owns a 5.16 ERA and 1.28 WHIP while allowing over 46% hard contact. When he last faced Toronto in Seattle just last week, he surrendered eight runs on eight hits, including three home runs in only four innings.

Now, on the road again, the numbers do not get any better. Over his last five road outings, Kirby holds a 5.40 ERA, 5.08 xERA, and 1.46 WHIP while giving up 50% hard contact, an 11.4% barrel rate, and a 30.7% line drive rate. Opponents in that stretch own a .321 xBA, .502 xSLG, and .363 xwOBA.

According to Batters-Box, Toronto will have one elite rated hitter and three with “Great” ratings tonight. Three of their top five hitters will bat from the right side. The last 30 right handed hitters Kirby has faced posted a .491 xBA, .975 xSLG, and .428 xwOBA against him, along with a 7.71 ERA and 7.46 xERA during that span. Left handed bats have not fared much differently, his numbers against them are nearly identical.

This feels like another strong spot for the Blue Jays to strike early. The Rogers Centre crowd will be electric from first pitch on. I do not expect Seattle to look as lifeless as they did in Game 6, but the mental mistakes were concerning.

Bonus Bet

Vladimir Guerrero Jr. to record a walk is priced around -110. I would either take the juice now or wait to see if he avoids a walk in his first at-bat to grab a live plus-money number. Guerrero Jr. is the most feared bat in this lineup and has been locked in all series, homers in three games and batting over .460 this postseason.

Keep an eye on the “Next At-Bat: walk/hit by pitch” market if he records a hit early; those props often sit north of +500 and offer great value.

Side Note: If you believe Toronto wins tonight and Guerrero Jr. contributes again, his ALCS MVP odds around -110 are worth considering if you are willing to pay the juice.

With only a few games left in the MLB season, this is the perfect time to look for mispriced props and hidden value. With football dominating the spotlight, sportsbooks often overlook baseball lines, creating opportunities for bettors to take advantage before the season wraps up.

Bonus: Vladimir Guerrero Jr. 1+ Walk (-110)

Best Bet: Blue Jays First Five Team Total Over 1.5 Runs (-140) odds via BetOnline
