Toronto Blue Jays at Seattle Mariners: Final Score & Recap

The Seattle Mariners shut out the Toronto Blue Jays 4-0 on July 5, 2026, at T-Mobile Park, a result that moved the DiamondIQ model's estimate of a Seattle win from 59% before first pitch to a certainty by the final out. Toronto managed just three hits and committed one error across nine innings, never mounting a sustained threat against a Mariners pitching staff that dominated from start to finish.

The decisive moment came in the bottom of the fourth inning, when Mitch Garver connected for a home run off Trey Yesavage, a swing that shifted win probability by plus 16.7 percentage points and effectively broke the game open. Garver finished as the game's top offensive performer, finishing with a WPA of plus 12.0 and an RE24 of plus 0.9. Seattle had already cracked the scoreboard in the third on a J.P. Crawford walk, which added 5.3 percentage points to the Mariners' win probability, and Crawford's steadiness throughout the night earned him a final WPA of plus 5.5. Toronto's best opportunity to change the complexion of the game evaporated in the top of the sixth, when Nathan Lukes grounded into a double play off Emerson Hancock, costing the Blue Jays 8.5 percentage points of win probability and ending any realistic hope of a rally.

Emerson Hancock was the story on the mound, posting a remarkable plus 26.3 WPA to lead all pitchers and rendering the Toronto lineup largely harmless. Gabe Speier contributed a plus 4.5 WPA in relief, and Tyler Rogers closed things out with a plus 0.8 mark. Yesavage absorbed the loss for Toronto, allowing the key early damage including the Garver home run and a Luke Raley double in the second that had begun to tilt conditions Seattle's way. The DiamondIQ model favors the Mariners, who converted what was a moderate pre-game edge into a thoroughly controlled victory.
