Chicago White Sox at Houston Astros: Final Score & Recap

The Houston Astros defeated the Chicago White Sox 6-3 on August 31, 2026, at Daikin Park, a result the DiamondIQ model's estimate anticipated as roughly a coin flip before first pitch at 52 percent in favor of the home side, but one that ended with Houston's win probability reaching 100 percent by the final out. The scoring opened in the third inning with Houston plating a single run, and the game's decisive sequence arrived in the fourth and fifth frames. Nelson Velázquez delivered the swing that most dramatically shifted the contest, a home run off Anthony Kay in the bottom of the fourth that added 21.0 percent to Houston's win probability and stood as the single highest-impact play of the night. Chicago had briefly generated life in the top of the fourth, when Munetaka Murakami drew a walk off Peter Lambert to add 10.7 percent to the White Sox's chances, followed by a Chase Meidroth single worth another 9.6 percent, but the Astros answered with two runs of their own in that same inning to neutralize the threat.

Houston extended its advantage in the fifth inning, with Cam Smith doubling off Trevor Richards for a 12.6 percent win-probability swing, and Christian Walker adding a walk worth 8.6 percent as the Astros pushed across three more runs to take a commanding lead. By the time Chicago scored its lone run in the seventh, the outcome was no longer in doubt. Velázquez finished as the game's top batter by WPA at plus-18.5 percent alongside a RE24 of plus-1.3, while Smith posted the strongest run-environment figure among position players at plus-1.6 RE24 to go with his plus-14.6 percent WPA. Colson Montgomery also graded out positively at plus-12.2 percent WPA and plus-1.6 RE24. On the mound, Bennett Sousa led Houston's relievers with plus-5.4 percent WPA, followed by Steven Okert at plus-4.5 percent, as the Astros bullpen closed out a game that the DiamondIQ model's estimate showed was effectively decided before the sixth inning began.
