Playing under American League rules with few reliable options on the bench this season, no manager had as little use for pinch hitters as Kansas City's Ned Yost. Now with the World Series shifting to San Francisco for Game 3 on Friday night, when the pitcher will bat instead of the designated hitter in the NL park, Yost might need to make some extra moves. Fortunately for the Royals, Billy Butler provides a potent bat to call upon - even if the slugger will get just one chance in the batter's box instead of his usual four. A lot of times in the National League you empty out your bench, obviously, more than you do in the American League.'' Butler already has three hits in the Series.
