New York Yankees at Kansas City Royals: Final Score & Recap

The Kansas City Royals defeated the New York Yankees 5-2 at Kauffman Stadium on October 1, 2023, with the DiamondIQ model's estimate of a home win beginning at 38% before game time and climbing to 100% by the final out. Kansas City built its advantage methodically through the middle innings, scoring two in the second, two in the fourth, and one in the fifth, leaving the Yankees with too steep a deficit to overcome despite a two-run sixth that briefly kept them in contention.

The decisive sequence centered on the second and fourth innings, where Michael King absorbed significant damage. MJ Melendez's home run in the bottom of the second added 7.4% to Kansas City's win probability, with Nick Pratto's single in that same frame contributing another 7.0%. Edward Olivares then extended the lead with a home run off King in the fourth, a swing worth 8.5% in win probability and the single largest positive play of the game from the batting team's perspective. On the other side, DJ LeMahieu's groundout into a double play in the top of the third cost New York 8.1% in win probability, extinguishing a potential rally against Zack Greinke. The Yankees' best moment came in the sixth, when Isiah Kiner-Falefa's single off Taylor Clarke, worth 7.1% in win probability, ignited a two-run inning, but Kansas City's bullpen held from there.

Zack Greinke led all pitchers with a WPA of plus-22.8%, making him the central figure in Kansas City's victory. Among position players, Dairon Blanco posted the game's top batting WPA at plus-9.0% alongside a RE24 of plus-1.3, edging Olivares, who finished at plus-7.0% WPA.
