Tony Sartori's Blue Jays vs Mariners Best Bet: Edge on the Mound

This contest is likely to mirror Game 2, as the key variables remain unchanged, except for the added pressure of potential elimination for Toronto. That situational factor has moved the betting line past a reasonable point, despite the clear statistical and experiential edge favoring Seattle.

The Mariners' Logan Gilbert is the more seasoned pitcher, while the Jays' Trey Yesavage may struggle again under the spotlight, particularly against a lineup that previously roughed him up.

At plus-money, it’s worth backing a Mariners team that earned a 10-3 road win the last time these starters squared off.

Pick: Mariners ML (+108)

Grant Neiffer's Blue Jays vs Mariners Best Bet: HR Prop With Value

Daulton Varsho Home Run (+550)

By Grant Neiffer

Toronto's Daulton Varsho gets to face Logan Gilbert, who has been a good matchup for righty power this season, but he grades out as a better matchup for lefty power.

Varsho has been great this season when healthy, hitting 22 home runs in 80 games, including the playoffs.

The ballpark is a plus for homers, and I have the true odds for the outfielder around +450.

Pick: Daulton Varsho Home Run (+550)



PRO's Blue Jays vs Mariners Best Bet: Second Time Around

Randy Arozarena 1+ Hits (-125)

By Action PRO

PRO projects Mariners left fielder Randy Arozarena with exactly one hit tonight, which represents a nice 7.7% edge against the market.

Although Arozarena has struggled this postseason, averaging .150, he had better splits on the road and playing on turf this season, which bodes well for this series' return to Rogers Centre in Toronto.

The Cuban outfielder already singled off Trey Yesavage in Game 2, while also getting hit by a pitch in another at-bat.

In this decisive matchup, you can back him at good value.

Pick: Randy Arozarena 1+ Hits (-125)



Bet Labs' Blue Jays vs Mariners Best Bet: Under Recommended

Under 7.5 (+100)

By Bet Labs

This system targets unders in MLB series games (Game 2 or later) where both teams have winning records, suggesting quality pitching and competitive matchups.

However, public betting leans toward the over — likely expecting fireworks between top teams — which creates contrarian value on the under.

By capitalizing on low public support for the under (≤35%), the strategy fades public perception in favor of market inefficiencies, especially when bettors overestimate offensive output late in a series.
