With both starters chased early, this became a matchup of bullpens. And no one stood taller than the 6-foot-5 Bumgarner, who added to his postseason legacy with a third victory this Series.
After Gregor Blanco misplayed Alex Gordon's drive for a single and two-base error, Bumgarner got Salvador Perez to pop foul to third baseman Pablo Sandoval for the final out.
The Giants ended a Series streak that had seen home teams win the last nine Game 7s. San Francisco took this pairing of wild-card teams after earning titles in 2012 and 2010.
Pitching on two days' rest after his shutout in Game 5, Bumgarner entered in the fifth with a 3-2 lead. After giving up a leadoff single to Omar Infante, he shut down the Royals.
