UNDATED (AP) —Major League Baseball launched the expanded replay era Monday, and saw instant results — a pair of missed calls by umpires got fixed fast, without any arguments. Opening day showed off the game's newest nod to modern technology in a sport that long relied on the eyes of its umps. The first overturned call came in Milwaukee. Atlanta Braves manager Fredi Gonzalez challenged the sixth-inning play at Miller Park in the season opener won by Milwaukee, 2-0. Brewers star Ryan Braun was originally called safe at first base by umpire Greg Gibson on a leadoff infield single fielded by third baseman Chris Johnson. The call was reversed to out after a review that lasted 58 seconds, and Braun ran back to the dugout. From now on, most every call can be challenged by a manager. When that happens, the final decision will come from a replay booth in New York, rather than the field. And instead of out or safe, fair or foul, disputes will be settled with two words new to baseball's lingo: confirmed or overturned.
