The New York Yankees defeated the Kansas City Royals 4-2 at Yankee Stadium on April 17, 2026, with the DiamondIQ model entering the game giving the home side a 73% win probability and watching that figure climb to 100% by the final out. New York's offense did its damage in concentrated bursts, scoring twice in the fourth inning and twice more in the eighth, while Kansas City managed only a single run in the sixth and another in the eighth against a Yankees pitching staff that largely controlled the game's tempo.
The decisive sequence came in the bottom of the eighth, when Ryan McMahon connected for a home run off Alex Lange that swung win probability by 35.6 points, the single largest play of the game by a wide margin. That blow effectively closed the door on any Royals comeback. Earlier, Ben Rice had set the tone with a fourth-inning home run off Michael Wacha worth 19.4 points of win probability, staking New York to what proved to be a durable early lead. Kansas City's most meaningful response came in the top of the eighth, when Vinnie Pasquantino hit a home run off Camilo Doval that added 19.0 points of win probability from the Royals' perspective, briefly tightening the margin before McMahon answered. A Bobby Witt Jr. fielding error in the sixth on a ball off Cam Schlittler provided Kansas City its other run, swinging 10.9 points in the Royals' favor.
Among individual performers, McMahon finished as the game's top batter by WPA at plus-35.6 with a RE24 of plus-1.9, while Pasquantino led Kansas City at plus-23.6 WPA despite being on the losing side. Ben Rice contributed plus-18.7 WPA and a RE24 of plus-1.5 for New York. On the mound, Brent Headrick was the game's most valuable pitcher by WPA at plus-18.3, with Michael Wacha adding plus-12.5 and David Bednar contributing plus-6.3 in support of a Yankees staff that held a lineup that managed just four hits and no errors across nine innings.
