Chicago White Sox at Houston Astros: Final Score & Recap

The Chicago White Sox handed the Houston Astros a 6-3 defeat at Daikin Park on September 29, 2026, building their lead inning by inning against a Houston club that entered with a 54 percent pre-game win probability according to the DiamondIQ model. Chicago scored in five of nine innings, constructing the margin methodically rather than in one sudden burst, while Houston's offense managed only six hits against a White Sox pitching staff that kept runners off the board in all but two frames.

The decisive turning point came in the top of the fifth, when Nelson Velázquez connected for a home run off Sean Newcomb that shifted win probability 10.7 percentage points in Chicago's favor, effectively breaking open a game that had been competitive through four innings. Colson Montgomery had already done damage in the top of the fourth with a home run off Miguel Ullola worth 7.0 percentage points of win probability, and Houston's best opportunity to claw back came in the bottom of the second, when a Lucas Spence strikeout against Hagen Smith cost the Astros 8.8 points of win probability and left momentum firmly with the visitors. Velázquez finished as the game's most impactful offensive player, posting a combined WPA of plus 14.6 percent alongside a RE24 of plus 1.4, while Braden Montgomery contributed a RE24 of plus 1.7 despite his lower plate-appearance profile. On the mound, Hagen Smith was the dominant force of the evening, accumulating a WPA of plus 21.1 percent that stood well above any other pitcher on either side, with Jordan Hicks and David Sandlin adding plus 5.6 and plus 4.7 respectively to secure the final three outs. The DiamondIQ model's estimate closed at zero percent for Houston, a complete reversal from where the game began.
