Venue: Flushing Meadows, New York Date: 30 August-12 September Coverage: Daily radio commentaries on BBC Radio 5 Live Sports Extra/BBC Sport website and app, with selected live text commentaries and match reports on the website and appBritish teenager Emma Raducanu thrashed Spain's Sara Sorribes Tormo to set up a potential US Open last-16 match with top seed Ashleigh Barty.
Raducanu, 18, won 6-0 6-1 against world number 41 Sorribes Tormo as her overseas Grand Slam debut continued with an extraordinary win in New York.
Sorribes Tormo is the highest-ranked player Raducanu has beaten.
She will face Barty on Monday if the Australian world number one beats Shelby Rogers later on Saturday.
After bursting onto the Grand Slam scene with a stunning run to the Wimbledon last 16 as a wildcard, Raducanu has now matched that breakout display in New York.
"I was playing very well and I know Sara is a tough opponent so I had to be on my game and worked so hard," said Raducanu, who won in one hour and nine minutes.
"I'm happy I maintained and stayed consistent."
The manner of the teenager's victory was scarcely believable, overwhelming an opponent who has reached a career-high ranking after winning 29 tour matches this year.
Raducanu's power and precision was too much for Sorribes Tormo to handle. The Briton walloped 23 winners and served solidly throughout, too.
Fittingly she sealed victory with another thunderous forehand winner before taking the acclaim of a New York crowd which appears to realise they are watching a star in the making.
"I had to hit through her and hit the corners," said Raducanu, whose number of winners outweighed 16 unforced errors.
"If you trade against her come second best and I took the game to her and I hit more winners than errors."
