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

The Boston Red Sox shut out the New York Yankees 5-0 at Fenway Park on September 13, 2023, moving the DiamondIQ model's estimate of a Boston win from 55% before the first pitch to a certainty by the final out. The game was a study in pitching dominance, with the Red Sox staff holding New York to six hits while Boston's offense built its margin in concentrated bursts. Tanner Houck led all pitchers with a WPA of plus-30.0%, followed by Garrett Whitlock at plus-16.6% and Michael King, who despite pitching for the Yankees, contributed a plus-12.3% WPA largely through strand situations that kept the game scoreless deep into the middle innings.

The decisive stretch began in the bottom of the seventh when Ceddanne Rafaela drove a home run off Greg Weissert, a swing worth plus-14.1% in win probability that transformed what had been a taut, low-scoring contest into a Boston lead. The Red Sox then added three runs in the eighth on a Trevor Story home run off Matt Bowman, a play worth plus-7.8%. New York had its best opportunity in the sixth inning, where Gleyber Torres cracked a double off Houck for a plus-8.5% swing, but Jake Bauers followed with a fielder's choice out that swung win probability minus-9.6% back toward Boston and ended the threat. An earlier double-play ball off Justin Turner's bat in the third had cost New York minus-10.0%, underscoring how thoroughly the Yankees squandered their limited chances.

Rafaela finished as the top batter by WPA at plus-16.8% with a RE24 of plus-1.2, his home run serving as the game's clearest inflection point. Torres was the lone Yankee bright spot at plus-13.2% WPA and a RE24 of plus-0.8, while Oswaldo Cabrera added plus-6.9% WPA and plus-0.9 RE24 for New York in a losing effort. The model leans toward crediting Houck's performance as the structural backbone of the outcome, given that his plus-30.0% WPA towered above every other contributor on either side.
