KANSAS CITY, Mo. — Billy Butler hit a tiebreaking single, Salvador Perez and Omar Infante drove in two runs each with big hits in a five-run sixth inning, and the Kansas City Royals beat the San Francisco Giants 7-2 Wednesday night to even the World Series at one game apiece. A night after the Giants opened with a 7-1 victory for their seventh straight Series win, Gregor Blanco led off the game with a home run against hard-throwing rookie Yordano Ventura. Alcides Escobar's RBI double in the bottom half off Jake Peavy and Butler's run-scoring single in the second put the Royals ahead 2-1 for their first lead of the Series, but Brandon Belt's RBI double tied the score 2-all in the fourth.
