Major League Baseball owners approved funding for replay expansion for the 2014 season, reports Jerry Crasnick of ESPN.com.
The Major League Baseball Players Association and the World Umpires Association still must approve the plan.
Rob Manfred, MLB's chief operating officer, said present and former umpires likely would make the decisions on contested calls after reviewing video at MLB headquarters in New York.
The current system calls for replay only for boundary calls involving home runs.
Managers will now get two challenges that can be used at any point in the game. If a certain play is challenged and overturned, the manager gets to keep that challenge. Managers cannot argue reviewable calls, but if a manager enters the field of play to argue a play, he must challenge.
