The Seattle Mariners defeated the Houston Astros 8-7 on April 11, 2026, at T-Mobile Park in a game defined by a dramatic fifth-inning rally and a tense finish that the DiamondIQ model ultimately resolved with a final win probability of 100 percent for Seattle. Houston entered with a pre-game road disadvantage, as the model placed Seattle's chances at 54 percent before first pitch, and the Mariners ultimately justified that lean despite surrendering a 6-0 deficit through the first four innings. The Astros had built their lead on 17 hits across the game, but Seattle's offense, though limited to just 7 hits, concentrated its damage at precisely the right moments.
The pivot of the entire contest came in the bottom of the fifth, when Julio Rodríguez hit a home run off Steven Okert that swung win probability by plus-25.9 percent in Seattle's favor, the single most impactful play of the game. That blow anchored a five-run inning that erased Houston's advantage and fundamentally reframed the game. The Astros threatened in the top of the ninth, but Yordan Alvarez's flyout off Andrés Muñoz carried a minus-16.8 percent swing against Houston, effectively sealing their fate before Seattle put the game away with a walk-off sequence. J.P. Crawford's single off Bryan Abreu added plus-15.9 percent, and Leo Rivas drew a walk from Abreu worth plus-12.5 percent to set the table for the final run.
By total WPA, Crawford led all players at plus-22.1 percent alongside a plus-2.0 RE24, while Cam Smith contributed plus-21.6 percent and a game-high plus-2.8 RE24, driven in part by his third-inning single off Luis Castillo that generated plus-13.8 percent for Houston before Seattle's comeback erased it. Rodríguez finished at plus-21.0 percent and plus-2.2 RE24. On the mound, Andrés Muñoz was Seattle's most valuable arm at plus-13.5 percent, with Bryan King adding plus-11.6 percent and AJ Blubaugh contributing plus-10.9 percent as the bullpen preserved what the offense had reclaimed.
