The designated hitter (DH) rule is applied in the same manner as in the World Series (and the All-Star Game prior to 2010). In an American League ballpark, both teams have the option to use a DH. In a National League ballpark, both teams' pitchers must bat. Teams from both leagues have both benefited and have been at a disadvantage when it comes to the DH rule in interleague play. For instance, Barry Bonds, who spent his entire career in the National League and actually won eight Gold Gloves earlier in his career, was used strictly as a DH later in his career when the San Francisco Giants played away interleague games due to his poor fielding. Conversely, Boston Red Sox slugger David Ortiz, who spent his entire career in the American League and was the Red Sox's regular DH, was forced to play first base when the Red Sox had away interleague games, forcing the Sox to give up good defensive fielding in favor of retaining Ortiz's power hitting.
