Seattle Mariners at Baltimore Orioles: Final Score & Recap

The Seattle Mariners defeated the Baltimore Orioles 6-3 at Oriole Park at Camden Yards on June 8, 2026, handing the home side a decisive loss in a game that turned almost entirely on one swing. The DiamondIQ model entered the night with Baltimore holding a 48 percent win probability, but that figure collapsed to zero by the final out, reflecting just how completely Seattle seized control.

The decisive moment came in the top of the fifth inning, when Josh Naylor connected on a home run off Anthony Nunez that shifted win probability by 35.1 percentage points in Seattle's favor. That single at-bat was the gravitational center of the contest, and Naylor finished as the game's top performer by WPA at plus-30.7 percent with a RE24 of plus-3.3, making him the clear difference-maker on the night. Taylor Ward also contributed positively, adding plus-10.4 percent WPA and a RE24 of plus-1.4, while Gunnar Henderson provided Baltimore's most meaningful offensive moment with a walk in the bottom of the seventh that nudged the Orioles' win probability up 7.6 percentage points, finishing the game at plus-16.7 percent WPA overall despite the loss.

Baltimore's attempts at a rally were repeatedly stifled on the mound. Matt Brash was Seattle's top pitcher by WPA at plus-7.7 percent, navigating a tense seventh inning in which Henderson's walk briefly opened a door before a Pete Alonso strikeout and a Colton Cowser groundout slammed it shut, the latter two plays costing Baltimore 10.8 and 11.5 percentage points of win probability respectively. A Samuel Basallo double play in the eighth, worth minus-14.0 percent WPA for the Orioles, further extinguished any remaining hope. Trey Gibson and Emerson Hancock each contributed roughly 6.8 and 6.7 percentage points of WPA respectively, reinforcing a Seattle pitching effort that held Baltimore to three runs on six hits with no errors allowed.
