MLB owners unanimously approved expanded instant replay, which will start in the 2014 season. The basic rules, according to MLB.com
Beginning this season, each manager will start a game with one challenge. If it is upheld, he retains his challenge but can never have more than two in a game. If the manager exhausts his challenges before the start of the seventh inning, he is out of luck, adding a new element of strategy to the game. Beginning in the top of the seventh, the crew chief is empowered to institute a review.
Another key change is that teams will now be allowed to show replays of close plays on the stadium video screens.
"Our fans will love it," [MLB Commissioner Bud] Selig predicted. "You know, the thought that, in the past, I could be sitting at home watching a game and get all the replays. And [somebody else] could be sitting at the ballpark and couldn't see any of these replays. That's just wrong."
In the past, teams weren't allowed to show those plays because of a 1976 incident in Yankee Stadium. Noted baseball writer Rob Neyer thinks this particular aspect won't be around long
, but it's an improvement while it lasts.
Previously, MLB had only used instant replay on questionable home runs. Now, it has been expanded to include a number of other situations, and this should be a great tool to improve the game and eliminate terrible calls. We'll see how it works out.
