Boston Red Sox at Athletics: Final Score & Recap

The Boston Red Sox held off the Athletics 5-4 at Sutter Health Park on July 30, 2026, in a game that shifted dramatically across the middle and late innings. Boston entered with the DiamondIQ model's estimate placing the home side at a 42% pre-game win probability, but Oakland never managed to take the lead and saw that figure fall to 0% by the final out. The Red Sox scored in three separate clusters — a run in the third, two in the Athletics' favor through four innings, a three-run burst in the fifth, one more in the sixth, and two critical insurance runs in the eighth — while their bullpen ultimately did enough to preserve the margin.

The decisive moments came in waves. Ceddanne Rafaela's double off Mason Barnett in the top of the fifth was the game's turning point in terms of early swing, adding 20.6% to Boston's win probability and keying the three-run frame that gave the Red Sox a lead they would not relinquish. The eighth inning delivered the knockout blow, as Willson Contreras and Wilyer Abreu hit back-to-back home runs off Luis Medina, each worth roughly 18-19% in win probability added, extending the lead to two. Oakland had a chance to respond when Tommy White grounded into a double play off Greg Weissert in the bottom of the eighth, a sequence that cost the Athletics 19.0% in win probability and effectively ended their best late threat.

Weissert was the standout performer on the mound, finishing with a WPA of plus-23.3%, the highest of any pitcher on either side, while Scott Blewett contributed plus-15.6%. Contreras led all batters with a WPA of plus-25.1% and a RE24 of plus-1.4, while Rafaela posted plus-22.1% and the game's top RE24 at plus-1.8. Aroldis Chapman closed it out in the ninth, getting Nick Kurtz to strike out — a swing of plus-21.4% in Boston's favor — to end a game in which the DiamondIQ model's estimate tracked Boston's control throughout the final four innings.
