Jack Draper, Harriet Dart and Cameron Norrie reached the quarter-finals on another day of British success in Eastbourne.
World number 108 Draper pulled off another victory over a top-15 player with a 7-5 7-6 (7-3) win over Argentine Diego Schwartzman.
Dart claimed two victories in one day, first beating Jil Teichmann and then Marta Kostyuk to reach the last eight.
British number one Norrie began the day by beating Brandon Nakashima 6-4 6-2.
Norrie will face Maxime Cressy next, while Dart plays two-time Wimbledon champion Petra Kvitova.
Draper could potentially face Ryan Peniston next, with the Briton's match against Spain's Pedro Martinez suspended at one-set apiece.
Peniston took the first set after a lengthy tie-break but play was halted with the score 7-6 (10-8) 3-6 3-2.
American Cressy beat Britain's Dan Evans 7-6 (7-2) 6-4 and Kvitova edged out Katie Boulter 5-7 6-0 7-5.
The in-form Beatriz Haddad Maia also ended Jodie Burrage's run with a dominant 6-1 6-2 win over the Briton.
American great Serena Williams will take to the court in the women's doubles once again when the 23-time Grand Slam singles champion and partner Ons Jabeur play Shuko Aoyama and Chan Hao-ching.

Draper fought well, first overturning a break deficit in the first set and then taking advantage of a loose service game from the fourth seed.
After going an early break up in the second, Draper served for the match at 5-3 but was broken to love, and it was Schwartzman who had the momentum in the tie-break.
However, Draper produced some fine counterpunching to come through and advance to the quarter-finals and join Norrie and Dart.
Dart has had a superb grass-court swing, having reached her first WTA quarter-final at Nottingham earlier this month.
She first beat a top-25 player in Switzerland's Teichmann before outlasting Kostyuk to become the first British woman in five years to make the last eight in Eastbourne.
Dart has been given a wildcard into Wimbledon, which begins on Monday, and is likely to rise back into the top 100 in the world rankings.
Battling Boulter edged out but Norrie advances
Boulter, who has been in superb form throughout the grass-court season, overturned a 5-3 deficit in the first set, winning four games in a row to take the lead.
Kvitova dominated the second set, with Boulter struggling with a niggle in her right elbow, before the Czech found a crucial break in the decider to advance.
Boulter, 25, has been given a wildcard into Wimbledon, which begins on Monday, and will arrive at SW19 full of confidence.
"She's beaten a top-10 player on the same surface and she will have the home crowd there again at Wimbledon," British player Naomi Broady told BBC Two.
"Hopefully, with the wins she's had here, she will have the opportunity to play on some big courts. She can go in and play freely with no expectations."
Compatriot Norrie, 26, suffered an early exit at Queen's last week but grew in confidence against Nakashima, backed up by a strong serving display.
After missing four break points early in the first set, Norrie eventually converted one for a 3-2 lead, and rattled through his next few service games with ease.
He slipped to 0-40 down as he served for the set but fought back to parity, before taking the set on a netted forehand from Nakashima.
The second set started in similar fashion, with Norrie converting his fourth break point in the opening game of the set before winning four games in a row.
Nakashima saved a match point on his serve before Norrie served out the match, clinching victory with a fine forehand winner.
