The Story
The Houston Astros defeated the Seattle Mariners 8-3 at T-Mobile Park on September 27, 2023, handing the home side a result the DiamondIQ model's estimate made look inevitable by the final out, swinging from a 53% pre-game home win probability to 0% in Seattle's favor. Houston collected 14 hits without committing an error, while the Mariners were hurt by a miscue of their own in a game that was effectively decided across two innings of damage.
The fourth inning was the turning point. Mauricio Dubón delivered the single biggest play of the night, a home run off Bryce Miller that shifted win probability 23.8 points in Houston's direction. Later in that same inning Yordan Alvarez added another home run off Miller, worth an additional 11.3 percentage points of win probability, pushing Houston's four-run frame into decisive territory. Seattle attempted a counter in the bottom half, with Eugenio Suárez singling off Framber Valdez for a 15.8-point swing that briefly tightened the contest, but the Mariners were unable to fully capitalize. Houston then put the game away in the seventh, when Kyle Tucker doubled off Matt Brash for an 11.8-point swing and Alex Bregman singled off Justin Topa to extend the lead further, capping a three-run frame that closed out any realistic path to a Mariners comeback.
Dubón finished as the top Houston performer by WPA at plus-17.0 with a RE24 of plus-1.4, while Alvarez posted plus-13.8 WPA. Eugenio Suárez led all players in WPA at plus-20.3 with a RE24 of plus-2.7, representing Seattle's most consequential offensive moment in an otherwise losing effort. On the mound, Héctor Neris led Houston's relievers with plus-7.9 WPA, followed by Kendall Graveman at plus-6.8, as the Astros bullpen held the line after Framber Valdez navigated the early challenge.
