The San Francisco Giants have clinched the World Series after victory over Kansas City Royals in a tight conclusion to the MLB season.

The Royals crushed the Giants 10-0 in Game Six to boost their hopes of securing their first title since 1985.

But in closely contested Game Seven, Madison Bumgarner inspired the Giants to their third title triumph in five years after pitching five scoreless relief innings while striking out another four en route - securing the MLB's Most Valuable Player Award.

Bumgarner, 25, shut out the Royals attempts to battle their way back into the contest after the Giants took a 3-2 lead. Building on his complete game shutout in Game Five, he allowed just one run in 21 World Series innings with 17 strike outs.

"He kept telling me 'I'm ready to go', he said just put me in anytime and it couldn't have worked out better," Giants manager Bruce Bochy said of Bumgarner. "The plan was to use Jeremy [Affeldt] early and hope we get to the fifth inning. A horse was out there and we rode him and it's historic what this kid has done. Really truly amazing."

"I wasn't thinking about finishing the game or how many innings I was going to go or pitch count," Bumgarner said. "I was just wanting to get outs.

"I can't lie to you anymore; I'm a little tired now."
