On August 28, 2008, Major League Baseball instituted an instant replay system in games to help decide some home runs calls. There are only three situations in which the replay can be used: (1) Was the potential homer fair or foul? (2) Did a fan interfere with a potential homer? (3) Did a potential homer go over the fence?
It is up to the crew chief to decide whether or not to use the replay system. A team cannot request or demand that it be used. Once the replay has been viewed and the umpires make their decision, no appeals are allowed and teams are not allowed to argue the call.
This system was put in place because of a series of calls in a 10-day period earlier that season which drew a lot of attention.
There was a use of a homer replay in 1999 before they were authorized. Details
