Britons Cameron Norrie and Harriet Dart lost their respective quarter-finals at Eastbourne on Thursday.
Top-seed Norrie was edged out 7-5 7-5 by American Maxime Cressy, leaving him with just one singles grass-court win to his name before Wimbledon.
World number 103 Dart lost 6-3 6-4 to Czech two-time Wimbledon champion Petra Kvitova.
However, there will be an all-British quarter-final as Ryan Peniston faces Jack Draper.
Peniston reached a second ATP quarter-final in a week as he beat Spain's Pedro Martinez 7-6 (10-8) 3-6 6-3 in a match that was delayed on Wednesday because of bad light.
