Boston Red Sox at Athletics: Final Score & Recap

The Boston Red Sox defeated the Athletics 4-2 in ten innings at Sutter Health Park on July 29, 2026, completing a comeback that the DiamondIQ model had given Oakland a 43 percent chance of winning before first pitch. The Red Sox finished with 12 hits against 8 for the Athletics, and Boston's two errors to Oakland's one proved inconsequential by the final out. The decisive blow came in the top of the tenth, when Andruw Monasterio drove a home run off José Suarez that swung win probability by 51.7 percentage points in Boston's favor, effectively ending Oakland's chances and accounting for the two-run margin that settled the game.

The ninth inning had briefly tilted the game toward the Athletics. Lawrence Butler's double off Aroldis Chapman moved the needle 17.5 percentage points in Oakland's direction, putting the tying run in position, but Jacob Wilson's strikeout to end the frame reversed all of that momentum and more, costing the Athletics 19.5 percentage points of win probability and stranding the threat. Chapman held, and the game moved to extras with Boston's lead intact. In the bottom of the tenth, Jonah Heim's flyout off Greg Weissert, which carried a 14.4-point swing in Boston's favor by closing out the inning, put the final punctuation on the victory.

Monasterio finished as the game's most impactful player by a wide margin, posting a WPA of plus-56.3 percent and an RE24 of plus-2.5. Jonah Heim and Lawrence Butler were the next most influential batters, contributing WPA figures of plus-25.8 and plus-24.3 respectively, though Butler's contributions came in a losing effort. On the pitching side, Brady Basso led Boston's staff with a WPA of plus-20.7 percent, followed by Elvis Alvarado at plus-11.7 and Oakland's Jacob Lopez at plus-11.0 for his work keeping the Red Sox at bay into the middle innings.
