Madison Bumgarner trotted in from the bullpen and kept San Francisco out of trouble, helping the Giants cling to a 3-2 lead over the Kansas City Royals after six innings in Game 7 of the World Series on Wednesday night. With the score tight, and Giants starter Tim Hudson pulled right away, it was only a matter of when - not if - the Giants would turn to their ace who'd already won twice this Series. He worked around a leadoff single by Omar Infante, then the big San Francisco lefty threw a perfect sixth in his first relief appearance since the 2010 NL playoffs. With the Giants trying to win their third title in five seasons and the Royals hoping to capture their second crown ever, neither manager wanted to be caught waiting too long to make a move.
