The San Francisco Giants handed the Kansas City Royals a 5-2 defeat on March 11, 2026, at Surprise Stadium, building an insurmountable lead with a four-run third inning that proved to be the defining sequence of the afternoon. The DiamondIQ model entered the game giving Kansas City a 54 percent chance of winning at home, but that estimate collapsed entirely as the Giants seized control early and never relinquished it.
The third inning was where the game was decided. Patrick Bailey opened the damage with a double off Bailey Falter that shifted win probability by plus 17.7 percent in San Francisco's favor, the single largest swing of the contest. Jerar Encarnacion followed with a home run off the same pitcher, adding another plus 16.9 percent swing that effectively put the game out of reach. Osleivis Basabe chipped in a single for a modest plus 3.9 percent contribution, while Christian Koss grounded into a fielder's choice that cost the Giants 5.5 percent, the only meaningful negative play in an otherwise dominant frame. Kansas City added single runs in the seventh and ninth innings, but the Royals mustered just three hits on the day and never seriously threatened to close the gap.
Encarnacion finished as the game's top offensive performer by WPA at plus 16.2 percent with a RE24 of plus 1.5, edging Bailey's plus 15.2 percent contribution. Carson Roccaforte added a plus 3.2 percent WPA showing in support. On the mound, Tyler Mahle led all pitchers with a plus 10.8 percent WPA, with Spencer Bivens contributing plus 8.3 percent and Ryan Walker adding plus 4.1 percent as the Giants' staff held Kansas City's lineup to a largely inconsequential afternoon.
