It probably won't make many baseball traditionalists happy, but all 30 major league teams have approved a plan to significantly expand instant replay starting this season.
Instant replay was first introduced to the game in 2008, but it's only been used for close calls on home runs.
Now baseball will add NFL-style challenges that will allow managers to fight an umpire's call.
Managers will get at least one challenge per game. If he wins the challenge, he'll get a second one. If he loses, he won't get any more.
After the seventh inning, an umpiring crew chief can request a review on his own if the manager has used up his challenges.
All reviews will be done by current umpires at a replay center in Manhattan.
Plays that can be challenged include home runs, ground rule doubles, fan interference, trap plays in the outfield and touching a base.
Balls-and-strikes cannot be challenged along with check swings, foul tips and obstruction and interference rulings.
Joe Torre, who serves as MLB's Executive Vice President of Baseball Operations, estimates that replay umpires will make their final rulings in no more than a minute to 90 seconds.
