In Lorenzo Cain's view, the Kansas City Royals have a big advantage when it comes to Game 6 of the World Series. ''We're definitely not facing Bumgarner tomorrow, so that definitely helps,'' the AL Championship Series MVP said Monday. Jake Peavy starts for the Giants on Tuesday night, with San Francisco leading the World Series 3-2 and one win from its third title in five years. Kansas City turns to a 23-year-old rookie Yordano Ventura in a rematch of Game 2 starters.
