The Story
The Kansas City Royals overcame a heavy pregame disadvantage to defeat the Houston Astros 7-5 at Minute Maid Park on September 22, 2023. The DiamondIQ model's estimate had Houston as a 74% favorite before first pitch, but Kansas City erupted for four runs in the first inning and added three more in the sixth, building a lead that ultimately held through a tense late comeback attempt by the Astros.
The game's most consequential sequence came in the eighth inning, when Chas McCormick's home run off Jackson Kowar swung win probability 13.8 points in Houston's favor, briefly reigniting the Astros' chances after they had fallen well behind. Houston continued to threaten in the ninth, but James McArthur induced a critical strikeout of Kyle Tucker to close the door, a play that shifted win probability 14.4 points toward Kansas City and represented the single largest swing of the contest. Earlier, a Tucker flyout off Cole Ragans in the first inning had been among the most damaging plays for Houston, costing 13.5 points of win probability at a moment when the Astros were still very much in striking distance.
Cole Ragans was the game's dominant individual performer, contributing a remarkable plus-40.4% WPA from the mound across his time in the game, anchoring the Kansas City pitching effort. Among position players, Nick Pratto led all batters with a plus-13.6% WPA, while Bobby Witt Jr. added plus-8.2% WPA despite finishing with a neutral RE24. McCormick was Houston's most impactful offensive player at plus-7.7% WPA and a plus-1.9 RE24, though his home run proved insufficient as the Royals held on for the final two-run victory.
