World number seven Coco Gauff thrashed Britain’s Jodie Burrage to reach the quarter-finals of the Eastbourne International.
American Gauff proved a step up in class for Burrage as she overpowered her 6-1 6-1 in exactly an hour.
Burrage lost 10 games in a row against the excellent Gauff, who will face doubles partner Jessica Pegula next.
Later, Britain’s Harriet Dart lost 6-3 6-4 in a closely-fought encounter against Latvia’s Jelena Ostapenko.
Dart, another Briton who has produced some good grass-court results, fought hard against Birmingham Classic champion Ostapenko.
However, the 26-year-old Ostapenko was the better of the two in the pressure moments to set up a quarter-final against either Ons Jabeur or Camila Giorgi.
In the men’s event, Britain’s Liam Broady was beaten 6-2 6-4 by Mikel Ymer of Sweden.
All three Britons have been given wildcards for Wimbledon, which begins on 3 July.
Burrage reached the final of the Nottingham Open at the start of the grass-court season, beating world number 23 Magda Linette and French veteran Alize Cornet on the way.
However, she always faced an uphill task against Gauff, who is 121 places above her in the world rankings and an excellent mover on a grass court.
The American won five games in a row to take the first set, breaking Burrage’s serve early with a fine backhand winner and consolidating her lead with a 124mph ace.
Burrage fought hard in the first game of the second set but a missed backhand handed Gauff the break, with the American reeling off another five straight games.
Burrage finally got on the board for 5-1 as Gauff struggled to serve out the match, but the Briton went long with a forehand on match point to hand Gauff victory.
“Jodie has had a couple of good weeks on grass and hopefully she can have a good time at Wimbledon,” Gauff, 19, said on BBC Two.
“Being in a town like Eastbourne where you can walk reminds me of home. It’s peaceful and I need that before getting into a Grand Slam.”
Gauff will face world number three Pegula next after the American beat Colombia’s Camila Osorio 6-2 1-6 6-3.
Kasatkina advances but men’s top seed Fritz out
Earlier, Russian ninth seed Daria Kasatkina beat 2021 Wimbledon runner-up Karolina Pliskova 3-6 6-3 6-3 to reach the last 16.
Pliskova, who has struggled for consistency over the past year, was annoyed by a Kasatkina forehand that was not called out at a decisive point in the third set.
She had led by a break in the deciding set but subsequently lost the point and her serve to hand Kasatkina a 4-3 lead.
The Russian then broke serve once again to set up a quarter-final meeting with either French second seed Caroline Garcia or Romanian qualifier Ana Bogdan.
Croatia’s Petra Martic advanced after eighth seed Beatriz Haddad Maia retired with illness when trailing 6-4 3-2, while 2014 champion Madison Keys beat China’s Wang Xinyu 6-2 7-6 (7-3).
However, defending champion and world number nine Taylor Fritz suffered a 7-6 (7-3) 7-6 (10-8) loss to American compatriot Mackenzie McDonald.
