KANSAS CITY, Mo. (AP) -- By the time Madison Bumgarner took the mound to throw his first pitch, the San Francisco Giants already held a three-run lead. It might as well have been 100 with the way MadBum and this orange-and-black bunch play in the World Series. Bumgarner carried a shutout into the seventh inning, Hunter Pence homered early and the Giants showed off their October poise, putting a sudden stop to the Kansas City Royals' perfect postseason roll by romping 7-1 in the Series opener Tuesday night.
