Many around the game of baseball are worried that the implementation of instant replay with slow an already long game, according to The Associated Press. "Major League Baseball and the media, they want instant replay, and we're going to have instant replay, so if it delays the game, then there's nothing we can do about it," World Umpires Association president John Hirschbeck said. The average time of a nine-inning game this season is 2 hours, 50 minutes, according to the Elias Sports Bureau. That mark is just one minute quicker than last season's average.
