Seattle Mariners at Baltimore Orioles: Final Score & Recap

The Seattle Mariners defeated the Baltimore Orioles 6-5 in ten innings at Oriole Park at Camden Yards on June 9, 2026, rallying from a deficit to hand Baltimore a walk-off loss in extras. The DiamondIQ model entered the game with the Orioles holding a 47 percent pre-game win probability, but the final figure dropped to zero as Seattle authored two separate comebacks across the final two innings.

The decisive swing came in the top of the tenth when Randy Arozarena connected on a home run off Rico Garcia, a blow that shifted win probability by 51.7 percentage points in Seattle's favor and effectively served as the game-winning hit. Arozarena finished as the game's most impactful performer by a wide margin, totaling a 62.6 percent WPA and a RE24 of plus-3.0. Before that, Mitch Garver had provided Seattle's earlier offensive spark with a fourth-inning home run off Trevor Rogers that added 31.8 percentage points of win probability. Baltimore mounted its own threat in the bottom of the tenth, as Leody Taveras delivered a single off Nick Davila that swung win probability 42.0 points toward the Orioles, but the rally fell one run short. The Orioles' ninth-inning push was equally dramatic, with Tyler O'Neill's double off José A. Ferrer shifting matters by 31.1 points, followed by Samuel Basallo's fielder's choice adding another 31.5, yet Baltimore was ultimately unable to complete the comeback, stranding the tying run.

On the pitching side, Logan Gilbert led Seattle's staff with a 19.6 percent WPA, while Gabe Speier contributed 13.3 percent in relief. Keegan Akin added 5.3 percent for the Orioles. Seattle out-hit Baltimore eleven to eight, and both teams committed one error in a tight, back-and-forth contest that the DiamondIQ model's estimates reflected was genuinely in the balance deep into the night.
