The Atlanta Braves handed the Philadelphia Phillies a 3-1 defeat at Citizens Bank Park on April 18, 2026, completing a game in which the DiamondIQ model's estimate of a home win probability opened at 28 percent and finished at zero. Atlanta scored all three of its runs in a decisive third inning against Cristopher Sánchez, while Philadelphia managed just a single run in the second and could not sustain any further threat. The Braves finished with 10 hits and committed no errors, while the Phillies managed five hits and were charged with one error.
The third inning was the turning point of the contest, as measured by the DiamondIQ model's win-probability framework. Mauricio Dubón's single off Sánchez represented the single largest swing of the game, adding 18.2 percent in win probability for Atlanta, and Austin Riley followed with a single of his own that added another 8.3 percent. Dubón finished as the top offensive performer by WPA at plus-13.1 percent with a RE24 of plus-1.0, while Ozzie Albies also contributed meaningfully at plus-4.7 percent WPA and plus-1.0 RE24. Philadelphia's best chance to claw back came in the bottom of the ninth when Rafael Marchán's flyout off Robert Suarez carried a 14.4 percent positive swing for the Phillies in retrospect, reflecting the leverage of the moment, though the outcome never changed. Brandon Marsh's ground into a double play in the fifth inning off Chris Sale had already deflated a Philadelphia rally by 10.4 percent.
On the pitching side, Chris Sale was the dominant figure, leading all pitchers with plus-17.5 percent WPA in favor of Atlanta. Dylan Lee followed in relief with plus-13.3 percent, and José Alvarado added plus-4.2 percent. Together, the Atlanta pitching staff held Philadelphia to a single run while the Braves offense did just enough damage in one inning to render the rest of the game largely a formality.
