A sizzling Ash Barty was left shaking her head after an exchange with an umpire following an embarrassing moment that stopped her match.
Ash Barty has started her US Open campaign in sizzling form after racing through the first set against Vera Zvonareva.
She was well on her way to a swift victory when the match was briefly suspended in the second set after the controversial electronic line-calling system crashed on Arthur Ashe Stadium, the centre court at the Flushing Meadows venue in New York.
The Aussie was just about to wrap up a service game when the system suddenly needed to be re-started, causing a delay of several minutes.
Barty spoke to the umpire after the annoying delay was announced and was heard on court microphones asking if human line judges could be brought onto court to replace the electronic system.
Her request was denied as a result of the tournament not using any line judges this year.
Barty was left shaking her head as she sat down waiting for a resumption of play.
In the end she was only forced to wait a few minutes and the break appeared to help her in the match when she came out and immediately broke her opponent’s serve.
Barty earlier put on an exhibition to race through the first set in just 24 minutes.
The 6-1 score happened so fast the tennis world barely had a chance to appreciate the Aussie’s sizzling start.
It has become so casually expected that the 25-year-old will now blitz her way through the opening rounds of grand slam events that Barty was playing the role of silent assassin even when she went up a break early in the second set.
The world No. 1 is chasing back-to-back grand slam titles after her historic win at Wimbledon.
She is in imperious form after also winning a WTA title two weeks ago at Cincinnati.
