Chicago White Sox at Boston Red Sox: Final Score & Recap

The Boston Red Sox shut out the Chicago White Sox 4-0 at Fenway Park on August 5, 2026, a result that moved the DiamondIQ model's estimate of a Boston win from 57% before the first pitch to a certainty by game's end. The Red Sox scored in the first, third, seventh, and eighth innings, never allowing Chicago a foothold in the contest. Sonny Gray was the dominant force on the mound, finishing with a DiamondIQ WPA of plus-27.2%, the highest of any player on either side. His most consequential moment came in the top of the sixth, when Colson Montgomery grounded into a double play that swung win probability 10.5 points against the White Sox, the single largest WPA event of the game. A Miguel Vargas single earlier in that same frame had briefly nudged Chicago's chances in the other direction by 5.3 points, but Gray extinguished the threat with the twin killing.

The game's decisive offensive blow came in the bottom of the third, when Wilyer Abreu drove a home run off Sean Burke that added 10.2 percentage points to Boston's win probability, the largest positive swing of the night for any batter. Abreu finished the game with a WPA of plus-6.6% and an RE24 of plus-1.0, leading all position players by that measure. Andruw Monasterio added a sacrifice fly off Huascar Brazobán in the seventh, a plus-5.7% WPA play that pushed the margin to three runs. Monasterio ended with a WPA of plus-4.5%, while Willson Contreras contributed the top RE24 among batters at plus-1.1, paired with a WPA of plus-3.3%. Chicago managed just four hits and committed an error, while Boston's bullpen arms Tyron Guerrero and Sean Newcomb combined for an additional 12.7 percentage points of WPA to close out a clean, wire-to-wire Red Sox victory.
