Athletics at Boston Red Sox: Final Score & Recap

The Boston Red Sox routed the Oakland Athletics 13-1 at Fenway Park on August 7, 2026, a result the DiamondIQ model's estimate largely anticipated, with Boston entering at a 70% pre-game win probability that climbed to 100% by game's end. The Red Sox wasted little time making that outcome feel inevitable, scoring five runs in the second inning and four more in the fourth to put the game well out of reach. Oakland managed just two hits and committed two errors, while Boston posted 15 hits against a combination of Athletics pitching that never found stable footing.

The decisive blow came in the bottom of the second, when Jarren Duran connected on a home run off Jack Perkins that shifted win probability by 12.7 percentage points, the single largest swing of the game. Wilyer Abreu followed up the same inning with a double off Perkins that added another 7.7 percentage points of win probability. A Caleb Durbin groundout in the same frame contributed a modest 4.5-percentage-point swing as Boston batted through its order, and Perkins was the central figure in the game's most consequential sequence. The only moment favoring Oakland among the top plays was Durbin's flyout to open the bottom of the first, which briefly shifted probability 5.5 points in the Athletics' direction before Boston seized control.

By top-line WPA, Duran led all batters at plus-12.2%, with an RE24 of plus-1.3, while Abreu posted the game's best run-environment impact at plus-2.5 RE24 to go with plus-8.6% WPA. Jake Rogers also contributed meaningfully at plus-5.0% WPA and plus-1.3 RE24. On the pitching side, Payton Tolle led Boston's staff with a plus-0.1% WPA contribution, reflecting how thoroughly the offense carried the afternoon.
