Britain’s Cameron Norrie fought back from two sets down to earn a memorable win over Argentine ninth seed Diego Schwartzman on day one of the US Open.
Norrie, ranked 76th, looked set for a routine defeat before turning it around to win 3-6 4-6 6-2 6-1 7-5 in New York.
Both struggled to hold serve in a match with 58 break points, Norrie saving two match points in the decider before winning in almost four hours.
Kyle Edmund beat Kazakhstan’s Alexander Bublik and plays Novak Djokovic next.
The British number two won 2-6 7-5 7-5 6-0 against the unpredictable Bublik, who initially upset the Yorkshireman’s rhythm before losing focus and allowing Edmund to take control.
Edmund, 25, faces a tough task to reach the third round of a Grand Slam for the first time in seven attempts, however, with 17-time Grand Slam champion Djokovic lying in wait in round two.
Serbia’s world number one Djokovic, who has won all 24 of his matches in 2020, brushed aside Damir Dzumhur of Bosnia-Herzegovina in his opener.
“It was a nice win in terms of the mentality. I play well when I’m expressing myself and explosive, when I start matches not in the right way I have to force that out of me,” said Edmund, who is ranked 44th.
“It was a good match to win, I could have fallen off and gone down two sets to love or two sets to one.”
The four other Britons in the singles – Andy Murray, Dan Evans, Johanna Konta and Heather Watson – play on Tuesday.
The US Open is the first Grand Slam event to be held since the coronavirus pandemic and is being played behind closed doors at Flushing Meadows.
A host of star names – including defending champions Rafael Nadal and Bianca Andreescu – have withdrawn because of health and travel fears, while Swiss great Roger Federer is missing because of a knee injury.
