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 fellow Briton Ryan Peniston, who enjoyed a stunning run at Queen's last week, or Spain's Pedro Martinez.
