The Associated Press is reporting that Major League Baseball will begin allowing instant replay to be used by umpires. It says:
For now, video will be used only on so-called "boundary calls," such as determining whether fly balls went over the fence or whether potential home runs were fair or foul. Video will be collected at the office of Major League Baseball Advanced Media in New York. If the crew chief at a game decides replay needs to be checked, umpires will leave the field, technicians at MLBAM will show umpires the video and the crew chief will make the call.This is a good thing. There is no benefit to the sport, its fans, or players to not having a call made correctly. Given how few "boundary calls" are close, this will be an exceedingly rare occurrence. People who don't like baseball already think it's slow. Those who love it, want the calls to be made correctly.
