KANSAS CITY, Mo. — Billy Butler must be one of the first players in World Series history to take a curtain call after an RBI single. Such responses usually happen after home runs, but the home crowd at Kauffman Stadium wouldn't let Butler get away Wednesday night, after he was removed for a pinch runner in Game 2, without waving "thanks." Butler put the Kansas City Royals ahead to stay with an RBI single against Jean Machi in the deciding sixth-inning rally. Back in the first inning, Butler ensured that the San Francisco Giants wouldn't keep a lead for long after they scored first for the second straight night. Butler's dual contributions were key in a 7-2 victory that evened the Series at a game apiece. "Especially at home, I felt like this definitely was a must-win game," Butler said. Royals manager Ned Yost said Butler's go-ahead hit was crucial.
