In what Commissioner Bud Selig says is a "historic day" for his sport, Major League Baseball is set to approve a massive expansion of the game's instant replay system.
USA Today's Bob Nightengale reported Thursday that the league will dramatically expand the uses for replay, which currently only is used to judge whether or not home run balls are fair or foul or if they clear the fence.
This expansion of replay will include the ability for team managers to challenge calls by umpires up to three times per game, USA Today says.
Nightengale reports that the expansion of instant replay is likely to be approved by Major League Baseball's owners in November and would be implemented in time for the 2014 season.
Replay was first implemented in Major League Baseball in August of 2008.
