Cleveland Guardians at Kansas City Royals: Final Score & Recap

The Kansas City Royals defeated the Cleveland Guardians 6-2 at Kauffman Stadium on May 4, 2026, in a game that began as a dead-even contest — the DiamondIQ model's estimate opened at exactly 50 percent for the home side — and ended with the model at 100 percent certainty in Kansas City's favor. Cleveland drew first blood with a David Fry home run off Michael Wacha in the top of the second, a swing that shifted win probability 8.5 percent toward the Guardians. But Wacha steadied after that, and the Royals answered emphatically in the bottom of the fourth, turning a narrow deficit into a commanding lead against Cleveland starter Tanner Bibee.

The fourth inning was the decisive sequence of the game. Nick Loftin's single off Bibee produced the largest single-play win-probability swing of the night at plus-15.8 percent, setting the stage for Bobby Witt Jr.'s home run, which added another 11.4 percent. Salvador Perez chipped in a single of his own for plus-8.6 percent in the same frame, as Kansas City plated four runs and effectively settled the outcome before the game reached the midpoint. Jac Caglianone extended the lead further with a home run off Matt Festa in the sixth, contributing a 9.2 percent swing that put the game entirely beyond reach.

On the individual side, Loftin finished as the game's top batter by WPA at plus-11.0 percent with a RE24 of plus-0.6, while Vinnie Pasquantino posted the strongest run-environment contribution among Kansas City hitters at plus-1.4 RE24 alongside plus-9.9 percent WPA. Witt Jr. rounded out the top three batters at plus-9.6 percent WPA. Michael Wacha was the story on the mound, generating plus-15.5 percent WPA to lead all pitchers in the game — absorbing the Fry homer without further damage and keeping Cleveland's lineup in check across what proved to be a thoroughly one-sided final result.
