The New York Yankees handed the Kansas City Royals a 7-0 shutout at Yankee Stadium on April 19, 2026, moving the DiamondIQ model's pre-game home win probability of 78 percent all the way to 100 percent by game's end. New York did the bulk of its damage in the first and fifth innings, each producing three-run frames, with a solo shot in the second inning rounding out the scoring. Kansas City managed six hits but could not push a single runner across against a Yankees pitching staff that controlled the game from the opening out.
The game's most consequential sequence began immediately, as Salvador Perez grounded out to close the top of the first with a win-probability swing of plus-5.9 percent in Kansas City's favor — a rare case where a Royals out actually represented a significant missed opportunity given the base-out state at the time. New York answered emphatically in the bottom half when Aaron Judge launched a home run off Cole Ragans for a plus-3.6 percent swing, and the Yankees never looked back. Ben Rice's home run off Ragans in the second inning generated the single largest positive swing of the night at plus-4.8 percent, while Trent Grisham's fifth-inning home run, also off Ragans, added another plus-4.5 percent. Starling Marte's grounded-into-double-play in the second compounded Kansas City's troubles, carrying a minus-3.4 percent swing.
By WPA, Ben Rice led all position players at plus-5.7 percent with a RE24 of plus-0.9, while Trent Grisham posted the strongest run-environment impact among hitters at plus-2.3 RE24 to go with his plus-4.5 percent WPA. On the mound, Ryan Weathers was the standout performer, accumulating plus-7.7 percent WPA as the Kansas City offense repeatedly failed to convert against him. Mason Black and Angel Chivilli each finished at plus-0.0 percent WPA in their respective outings.
