Two experimental replay systems will be installed this month at Yankee Stadium and Citi Field in New York to test their ability to review fair/foul calls, ESPN.com reported Friday.
The systems won't be used to reverse or confirm calls at this point, officials said. Instead, MLB will determine which system would best fit baseball's needs.
"Hawkeye," the camera-based technology used in tennis, will be tested at Citi Field, both during Mets games in September and on off-days. A radar-based system, similar to the technology used to track shots in golf telecasts, will be tested at Yankee Stadium. The technology has not been used before to review calls in any sport.
Both systems will be tested again during the Arizona Fall League.
