Instant replay was not expanded in 2012, and Executive Vice President of Baseball Operations Joe Torre confirmed that instant replay would again not be expanded in time for Opening Day 2013, putting off plans for another season. On August 15, 2013, Major League Baseball announced that it would expand its video review process for the 2014 season, granting managers one challenge over the first six innings of games and two from the seventh inning until the end of the game. Calls that are challenged would be reviewed by a crew in MLB headquarters in New York City, who make the final ruling.
