The New York Yankees rolled past the Kansas City Royals 13-4 at Yankee Stadium on April 18, 2026, a result the DiamondIQ model's estimate reflected clearly, as pre-game home win probability stood at 76 percent and finished at 100 percent. The game was effectively decided in the third inning, when the Yankees sent a crushing wave through the Royals' Noah Cameron. Amed Rosario connected for a home run that shifted win probability by plus 13.3 percent, and Cody Bellinger followed with a home run of his own for an additional plus 12.9 percent swing. A fielding error charged to Cameron added another plus 7.6 percent to New York's advantage, turning the third inning into a five-run frame that the Royals never recovered from. The Yankees added two more in the fourth and three in the sixth before Kansas City managed any runs of consequence, scratching out two apiece in the seventh and ninth against a bullpen that had long since taken control.
Bellinger finished as the game's top performer by WPA at plus 13.5 percent with a RE24 of plus 4.8, while Rosario's plus 12.3 percent WPA and Escarra's plus 10.2 percent WPA rounded out a balanced offensive effort for New York. The Yankees' pitching staff was nearly immaculate, surrendering no errors across 13 hits and holding Kansas City to four runs. Will Warren led the pitching corps with a plus 0.7 percent WPA contribution, with Mitch Spence and Paul Blackburn each finishing at neutral. Cameron absorbed the bulk of the damage, as the five biggest win-probability swings of the entire game occurred during his appearances, including two negative plays in the first and second innings that foreshadowed the collapse to come in the third.
