New York Yankees at Arizona Diamondbacks: Final Score & Recap

The Arizona Diamondbacks defeated the New York Yankees 5-3 at Chase Field on September 19, 2026, in a game that remained tightly contested through eight innings before a decisive ninth-inning blow sealed the outcome. The DiamondIQ model entered the game with the home side at a 48 percent win probability, a figure that would ultimately reach 100 percent, though the path there ran through a lead-change sequence in the middle innings and one swing that ended all doubt.

The game's scoring began in the fifth inning, when Jordan Lawlar's triple off Cam Schlittler gave Arizona an early foothold, a play that shifted win probability by 20.3 points in the Diamondbacks' favor. New York answered in the top of the sixth with back-to-back home runs off Kevin Ginkel, Austin Wells connecting for a swing worth plus 14.6 percent and Heliot Ramos following with one worth plus 13.8 percent, pushing the Yankees in front and swinging momentum sharply toward the visitors. Ben Rice then grounded into a double play in the top of the seventh off Brandyn Garcia, a sequence that cost New York 8.8 points of win probability and marked the last meaningful chance the Yankees would generate. Garcia finished as the game's top pitcher by WPA at plus 16.5 percent, with Juan Morillo and Paul Blackburn each contributing to keeping New York off the board in the final frames.

The decisive moment came in the bottom of the ninth, when Pavin Smith hit a home run off Michael Fulmer that added 35.9 points of win probability in a single stroke, the largest swing of the game by a significant margin. Smith finished as the top batter by WPA at plus 35.9 percent with a RE24 of plus 1.7, while Austin Wells led New York at plus 22.8 percent and plus 1.5 RE24 despite being on the losing side. Ildemaro Vargas contributed quietly with a plus 12.7 percent WPA showing for Arizona. The DiamondIQ model favors Arizona's bullpen construction as a decisive factor in the final outcome.
