The Giants built their advantage through four scoreless innings and then plated four runs in the bottom of the fourth to take control, but Kansas City chipped away with single runs in the sixth and seventh before an explosive three-run eighth inning turned the game.

The decisive moment came in the top of the eighth, when Salvador Perez connected on a home run off Ross Stripling that swung win probability by 36.5 percentage points in the Royals' favor, the single largest swing of the game.

The Royals added an insurance run in the ninth off Camilo Doval, with Vinnie Pasquantino delivering a double worth 17.5 percentage points in win probability, and Kyle Isbel's subsequent strikeout looking swing turned into a 31.3-point swing when the inning ended without further damage.

Aroldis Chapman closed the game in the ninth, and Michael Conforto's strikeout to end the contest represented a 31.6-point swing that sealed the outcome. Perez finished as the game's top offensive performer by WPA at plus-38.5%, backed by a RE24 of plus-2.8, making him the clear catalyst of the comeback. Sean Manaea led all pitchers with a plus-15.8% WPA contribution, followed by Clarke at plus-10.9%, as Kansas City's bullpen ultimately preserved what the lineup had clawed back from a four-run hole.
