With every pitch, Madison Bumgarner etched his place among the World Series greats. The long, tall lefty kept slinging away and put the San Francisco Giants just one win from yet another championship, throwing a four-hitter to beat the Kansas City Royals 5-0 Sunday night for a 3-2 Series edge. Hardly menacing on the mound, Bumgarner was simply untouchable - again. As ''MVP! MVP!'' chants broke out from each packed corner of AT&T Park, Bumgarner finished off the first World Series shutout in 11 years.
