Boston Red Sox at Athletics: Final Score & Recap

The Boston Red Sox handed the Athletics a 4-2 defeat at Sutter Health Park on July 27, 2026, with the decisive action concentrated almost entirely in the sixth inning. The DiamondIQ model entered the game giving the home Athletics a 43 percent win probability, but that number collapsed to zero by the final out. Boston carried a scoreless game into the top of the sixth before Ceddanne Rafaela delivered the pivotal blow of the night, a home run off José Suarez that swung win probability 42.8 percent in Boston's favor and effectively resolved the contest. Connor Wong added a double off Jack Perkins later in the frame to extend the Red Sox advantage, pushing his own WPA contribution to plus 8.5 percent on that play. Oakland answered in the bottom of the sixth when Jonah Heim connected for a home run off Payton Tolle, a swing worth plus 11.2 percent win probability for the Athletics, but it proved to be the only meaningful foothold the home side could manage.

From a performer standpoint, Rafaela finished as the game's most impactful player by a wide margin, posting a WPA of plus 37.2 percent alongside a RE24 of plus 2.6. On the pitching side, Jack Perkins led all pitchers at plus 28.5 percent WPA despite surrendering the pivotal Rafaela home run, as his overall work through the game limited further Boston damage. Garrett Whitlock added plus 13.3 percent WPA out of the Boston bullpen, and Jovani Morán contributed plus 8.8 percent. Oakland's final threat dissolved in the ninth when Henry Bolte struck out against Aroldis Chapman, a moment that subtracted 9.5 percent from the Athletics' win probability and closed the door on any late rally. Boston's line showed two errors against none for Oakland, though the Athletics' six hits could not overcome the Red Sox's four-run sixth.
