Hall of Famer Juan Marichal mingled in the San Francisco clubhouse and waited patiently for his chance to share a kind, congratulatory word with Madison Bumgarner. What Bumgarner did to pitch the Giants within one victory of another World Series championship certainly was. The Southern southpaw tossed a four-hit gem in his latest brilliant postseason start, and the Giants beat the Kansas City Royals 5-0 on Sunday night to reach the cusp of a third championship in five years. ''It's what you set your sights for before you go out there, you want to finish the game,'' Bumgarner said.
