The Story
The Athletics handed the Boston Red Sox a 4-3 defeat at Fenway Park on August 9, 2026, completing the comeback against a team the DiamondIQ model had given a 68% pre-game win probability. Oakland chipped away at that edge inning by inning, scoring single runs in the first and fourth before Boston briefly seized control with two runs in the fifth. The Athletics answered with runs in the eighth and ninth to close it out, leaving the model's final estimate of a Boston win at 0%.
The decisive blow came in the top of the ninth when Max Muncy doubled off Aroldis Chapman, a swing that shifted win probability by plus 38.5 percentage points and stood as the game's single largest play by that measure. Muncy finished as the game's top offensive performer with a cumulative WPA of plus 39.7% and a RE24 of plus 0.5. The Athletics also got meaningful contributions from Jonah Heim, whose double off Garrett Whitlock in the eighth carried a plus 14.4% win-probability swing and set the stage for what followed. Caleb Durbin added a walk off Hogan Harris in the ninth that registered plus 12.3% WPA, matching Jahmai Jones for the third-highest individual offensive mark on the night.
Boston's best chance to close the door came in the bottom of the ninth against Hogan Harris, but the inning unraveled. Ceddanne Rafaela's lineout added plus 18.8% WPA from Boston's perspective before Nick Sogard's forceout swung the needle back minus 14.9%, effectively ending the threat. On the mound, Oakland's bullpen held the lead with Elvis Alvarado leading relievers at plus 10.9% WPA, followed by Jovani Morán at plus 8.5% and Tyron Guerrero at plus 7.3%, a trio that collectively preserved the one-run margin through the game's final frames.
