PARADISE VALLEY, Ariz. (AP) - Major League Baseball will greatly expand instant replay to review close calls starting this season.
MLB announced Thursday that owners, players and umpires have approved the new system.
Each manager will be allowed to challenge at least one call per game. If he's right, he gets another challenge. After the seventh inning, a crew chief can request a review on his own.
The so-called "neighborhood play" at second base on double plays cannot be challenged. Many had safety concerns for middle infielders being wiped out by hard-charging runners if the phantom force was subject to review.
All reviews will be done by current MLB umpires at a New York office. Additional umpires will be hired to create a large enough staff.
