Baltimore Orioles at Seattle Mariners: Final Score & Recap

The Baltimore Orioles defeated the Seattle Mariners 5-3 at T-Mobile Park on June 17, 2026, handing Seattle a loss despite the DiamondIQ model's pre-game estimate of a 58% home win probability for the Mariners. Baltimore scored in four separate innings, building a lead that Seattle could not overcome, and the model's final win probability for the home side fell to 0%.

The game's decisive sequence began in the third inning when Gunnar Henderson launched a home run off George Kirby, a swing that shifted win probability 20.0 percentage points in Baltimore's favor and stood as the single most impactful play of the night. Kirby was struck again in the sixth, when Leody Taveras ripped a triple that added another 14.7 points of win probability to the Orioles' ledger. Baltimore extended its advantage further in the seventh on a Blaze Alexander single off Alex Hoppe, worth 6.0 percentage points. Seattle generated its most meaningful threat in the bottom of the fourth, where Dominic Canzone's single off Kyle Bradish registered a 9.7-point swing for the home side, and the Mariners pushed across two runs in the ninth, but Ryan Helsley stranded the tying run by striking out Connor Joe, a pivotal out that added 14.4 points of win probability to Baltimore's column.

By the DiamondIQ model's accounting, the standout performers skewed heavily toward Baltimore. Henderson finished with a WPA of plus-15.6 and an RE24 of plus-1.3, while Taveras posted a WPA of plus-12.0. Canzone was the most impactful bat in the game by WPA at plus-16.0 and led all hitters with an RE24 of plus-2.0, though that came in service of Seattle's effort. On the mound, Kyle Bradish was the clear story, accumulating a WPA of plus-33.1, easily the highest mark of any player on either side and the foundation upon which Baltimore secured the road victory.
