HAWK EYE LIVE ELECTRONIC LINE CALLING TO REPLACE LINE JUDGES AT US OPEN

Chatara, The U.S. Tennis Association and the sport's two leading professional tours- the ATP and WTA, announced on Monday that Hawk-Eye Live electronic line-calling will be used for all competition courts at the US Open in 2021 and at seven of the nine US Open Series events preceding it.

Electronic line calling technology was also used at last year's US Open, apart from at the Arthur Ashe and Louis Armstrong stadiums. The technology was also deployed at the Australian Open, a move largely welcomed by players.

The USTA said in a statement that seven of the nine ATP and WTA tournaments on the US swing would use the technology on all competition courts in 2021.

"The USTA implemented electronic line-calling for the 2020 Western & Southern Open and US Open on all courts except Arthur Ashe and Louis Armstrong Stadiums," the governing body added. "In total, Hawk-Eye Live made upwards of 314,000 calls during the two tournaments."

During a fourth-round match at Ashe against Pablo Carreno Busta last September, Djokovic was defaulted from the US Open for inadvertently hitting a line judge in the throat with a ball in frustration following a point during his match.

It was a shocking stop to the No. 1-ranked Djokovic’s 29-match winning streak and his chance to add to his Grand Slam title collection.
