San Francisco Giants at Seattle Mariners: Final Score & Recap

The Seattle Mariners defeated the San Francisco Giants 6-3 at T-Mobile Park on July 19, 2026, handing San Francisco a loss in a game the DiamondIQ model had favored the home side at 61% before first pitch. The Mariners controlled the contest throughout, holding a clean defensive ledger with zero errors while the Giants committed two, and Seattle's eleven hits to San Francisco's five told the story of a team that largely had its way offensively on its own turf.

The decisive swings came from Cole Young and Luke Raley in the middle innings, both connecting for home runs off Giants reliever Adrian Houser. Raley's blast in the bottom of the sixth added 14.7 percentage points to Seattle's win probability, and Young followed an inning later with a home run that pushed the model's estimate by another 16.1 points, effectively sealing the outcome. San Francisco's best chance to shift momentum came in the top of the fifth when Luis Arraez doubled off Logan Gilbert for a 10.1-point swing, and the Giants had spotted themselves two runs in the opening frame, but Mitch Garver's bases-loaded ground into a double play in the second inning, a swing of negative 11.9 points, snuffed an early Seattle threat and proved a pivotal sequence in the home team's favor.

By WPA, Cole Young led all batters at plus 16.5 percent with a RE24 of plus 1.7, while Luke Raley posted plus 14.3 percent and Jung Hoo Lee contributed plus 11.3 percent despite a slightly negative run-expectancy figure. On the pitching side, Eduard Bazardo paced Seattle's relief corps with a WPA of plus 8.5, supported by Sam Hentges and Gabe Speier at plus 4.5 apiece. The DiamondIQ model closed at 100 percent confidence in a Seattle win, a reflection of how thoroughly the Mariners managed the game from the third inning onward.
