Jack Draper, Harriet Dart and Cameron Norrie reached the quarter-finals on another day of British success in Eastbourne.
The world number 108 Draper achieved another victory over a player of the top 15 with 7-5 7-6 (7-3) over the Argentine Diego Schwartzman.
Dart scored two victories in one day, defeating first Jill Taichman and then Martha Costiuk to reach the last eight.
British number one Norrie started the day beating Brandon Nakashima 6-4 6-2.
Nori will then face Maxim Cressi, while Dart plays two-time Wimbledon champion Petra Kvitova.
Draper could possibly face a British compatriot Ryan Penistonwho enjoyed a stunning run at Queen’s last week or Spaniard Pedro Martinez.
American Cressy beats Britain Dan Evans 7-6 (7-2) 6-4 and Kvitova went out Katie Boulder 5-7 6-0 7-5.
The updated Beatriz Haddad Maia is also finished Jodi Baraj runs with a dominant 6-1 6-2 victory over the Briton.
Great American Serena Williams will go to the women’s doubles court once again when the 23-time Grand Slam champion and partner in the Ons Jabeur single will play Shuko Aoyama and Chan Hao-ching.
Draper fought well, initially overturning a break deficit in the first set and then taking advantage of a loose serve from the fourth seed.
After an early break in the second, Draper served for the match at 5-3, but was disappointed and it was Schwartzman who had the momentum in the tie break.
However, Draper made some nice inversions to advance to the quarterfinals and join Norry and Dart.
Dart had a great swing on the grass, having reached her first WTA quarterfinal in Nottingham earlier this month.
She first won a top-25 player in Switzerland’s Teichmann before overtaking Kostyuk to become the first British woman in five years to make the last eight in Eastbourne.
Dart received a wild card at Wimbledon, which starts on Monday, and is likely to rise again in the top 100 of the world rankings.
Batling Boulter comes out, but Norrie moves on
Boulter, who has been in excellent form all season on the pitch, overturned the deficit 5-3 in the first set, winning four consecutive games to take the lead.
Kvitova dominated the second set, with Boulter struggling with a sting in her right elbow before the Czechs found a crucial break in the crucial to move on.
Boulter, 25, received a wild card at Wimbledon, which starts Monday, and will arrive at SW19 confident.
“He beat a top-10 player on the same surface and he will have the audience there again at Wimbledon,” British player Naomi Broady told BBC Two.
“Hopefully, with the victories he has had here, he will have the opportunity to play in some big stadiums. He can come in and play freely without expectations.”
Compatriot Norrie, 26, suffered an early departure from Queen’s last week, but boosted his confidence in Nakashima backed by a strong serve.
After losing four break points early in the first set, Norrie eventually converted one to a 3-2 lead, and dropped his next serve easily.
He slipped to 0-40 as he served for the set, but fought on par, before taking the set with nets from Nakashima.
The second set started in a similar way, with Norrie converting his fourth break point into the opening game of the set before winning four games in a row.
Nakashima saved a match point on his serve before Norrie served the match, earning the win with a good forehand winner.
