Via ESPN:
Major League Baseball will begin installing two new, experimental replay systems this month at Yankee Stadium and Citi Field in New York to test their viability for reviewing fair/foul calls.
The systems won’t be used to reverse or confirm calls at this time, according to MLB officials familiar with the plans. But their installation will enable MLB to determine which system would best fit baseball’s needs.
Done right, technology like this will reduce arguments and speed up games. Baseball needs this.
