Arizona Diamondbacks at Boston Red Sox: Final Score & Recap

The Arizona Diamondbacks handed the Boston Red Sox a 4-1 defeat at Fenway Park on August 24, 2024, holding Boston scoreless through eight innings before a meaningless ninth. The DiamondIQ model opened the game with a nearly even split, assigning Boston a 49% pre-game win probability, but that figure collapsed to 0% by the final out. Arizona's offense did its damage in concentrated bursts, scoring two runs in the fourth and two more in the seventh while Zac Gallen methodically dismantled the Red Sox lineup.

The pivotal moment came in the top of the fourth inning when Eugenio Suárez laced a double off Kutter Crawford, a swing that shifted win probability by 20.5 percentage points in Arizona's favor and stood as the single most consequential play of the game. Suárez finished as the top offensive contributor by WPA at plus 17.1%, also adding a run expectancy of plus 1.0 RE24. Boston had opportunities to respond but repeatedly squandered them, most notably in the sixth when Rob Refsnyder grounded into a double play off Gallen, swinging win probability 8.0 points back toward Arizona. Arizona extended its lead in the seventh on a Jake McCarthy walk off Brennan Bernardino that moved the needle another 8.8 points, effectively sealing matters. Rafael Devers was Boston's most productive bat by WPA at plus 8.3%, while Joc Pederson contributed plus 6.4% on the Arizona side.

Gallen was the dominant force on the evening, posting a game-leading plus 29.4% WPA across his outing and keeping Boston's lineup largely quiet through the critical middle innings. Relievers Zack Kelly and Ryan Thompson combined to add another plus 8.0% WPA in support, allowing Arizona to close out the shutout before Boston's lone run in the ninth provided only cosmetic consolation. Arizona finished with six hits and no errors, while Boston managed five hits but could not convert any of them into runs until the outcome had long been decided.
