A person familiar with the plan tells The Associated Press that Major League Baseball will tweak its postseason tradition and add a seventh umpire to rotate between the replay booth and field for the World Series and league championship series.
The extra umpire this year will work home plate in Game 1, go to right field in Game 2 and then shift to the replay booth in New York for the rest of the series. Another ump will handle two games in replay before working the remaining games on the field.
The person spoke to the AP under condition of anonymity because umpire assignments haven't been announced for the World Series and the AL and NL championship series.
MLB began having six umpires on the field starting at the 1947 World Series, when rookie Jackie Robinson and the Brooklyn Dodgers opened at Yankee Stadium.
