The San Francisco Giants piled up runs relentlessly in an 11-4 victory over the Kansas City Royals on Saturday to level the 110th World Series at two games apiece. With the win, the Giants gained some much-needed breathing room, ensuring that Major League Baseball's best-of-seven championship showcase will return to Kansas City for game six on Tuesday. Before then, the Giants will have a chance to regain the Series lead at home when they host game five on Sunday. The Royals, back in the post-season for the first time since they won their only World Series crown in 1985, had won two games straight to put the Giants under pressure.
