New York Yankees at Boston Red Sox: Final Score & Recap

The New York Yankees completed a 4-1 victory over the Boston Red Sox at Fenway Park on September 12, 2023, holding the home side scoreless after the first inning and riding strong pitching to close out the road win. The DiamondIQ model's estimate had Boston entering with a 54% win probability, but that number eroded steadily and finished at 0% as the Yankees methodically shut the door. New York finished with nine hits and committed no errors, while Boston managed six hits and was hurt by one of their own defensive miscues.

The pivotal moments came in bunches. Estevan Florial's fifth-inning single off Kutter Crawford supplied a 10.8% win-probability swing in New York's favor, opening the scoring and tilting the game's balance. Boston's best opportunity to respond came in the seventh, when Ceddanne Rafaela's double off Zach McAllister briefly injected life into the Red Sox half of the inning with a 10.6% swing, but Justin Turner's pop out against Anthony Misiewicz immediately reversed that momentum, costing Boston 10.5 percentage points. The defining sequence arrived in the eighth inning, when Rafaela lined out against Matt Bowman in a moment that swung win probability by 22.1 points away from Boston, effectively ending any realistic path to a comeback. Connor Wong's strikeout in the same frame, a 10.6% swing, compounded the damage.

On the individual ledger, Isiah Kiner-Falefa and Estevan Florial each posted 8.6% WPA contributions for New York's offense, with Florial also generating a positive 1.3 RE24, and Oswaldo Cabrera added 6.5% WPA. On the mound, Matt Bowman led all pitchers with 23.3% WPA, his eighth-inning work proving the most consequential of the night. Anthony Misiewicz contributed 20.3% WPA and Carlos Rodón added 14.3%, giving the Yankees a trio of relievers who collectively suffocated Boston's late-game hopes.
