Defeat for the Czech seventh seed means there are no top-10 seeds left in the women's draw
Serena Williams wins 18th straight Wimbledon match to complete quarter-final line-up
Serena Williams raced into her 13th Wimbledon quarter-final as the seven-time champion thrashed Russian qualifier Evgeniya Rodina 6-2, 6-2 in just 62 minutes on Monday.
Williams, who won the Wimbledon title on her last two visits in 2015 and 2016, is now on an 18-match winning streak at the All England Club.
The 36-year-old faces Italian world No 52 Camila Giorgi on Tuesday for a place in the semi-finals.
Former French Open champion Jelena Ostapenko recovered from a slow start to race into the quarter-finals, defeating Belarusian world No 50 Aliaksandra Sasnovich 7-6, 6-0.
Ostapenko, the 12th seed from Latvia, needed to recover from 2-5 down, but then won 11 of the next 12 games to take her place in the last-eight.
Ostapenko will take on Dominika Cibulkova for a place in the semi-finals after the Slovakian defeated Taiwan's world No 48 Hsieh Su-Wei 6-4, 6-1.
Cibulkova is ranked 33rd in the world and controversially missed out on being seeded at Wimbledon when tournament officially moved up seven-time champion Serena Williams into the seedings despite the American being ranked outside the top 150 following her maternity leave.
Kiki Bertens of the Netherlands is also through to the quarter-finals after she defeated Czech seventh seed Karolina Pliskova 6-3, 7-6. Pliskova's exit means there are no players seeded in the top-10 remaining in the women's draw.
Bertens will face Julia Georges in the next round after the German 13th seed ended Croatian Donna Vekic's run with a 6-3, 6-2 victory.
Italy's Camila Giorgi beat Russia's Ekaterina Makarova 6-3, 6-4 and will await the winner of Williams' match with Evgeniya Rodina.
Russian 14th seed Daria Kasatkina booked her first quarter-final appearance with a 6-7, 6-3, 6-2 victory over Belgium's Alison Van Uytvanck on Monday.
Kasatkina made her grand slam last eight debut at the French Open in June and has followed that with another impressive run at the All England Club.
The 21-year-old was too strong for world No 47 Van Uytvanck, who failed to emulate her shock second round win over last year's Wimbledon champion Garbine Muguruza.
Kasatkina, who failed to get past the third round in her two other visits to the grass-court Grand Slam, will play former Wimbledon finalist Angelique Kerber for a place in the semi-finals.
Kerber is the highest seed remaining after the 2016 finalist defeated the in-form Belinda Bencic 6-3, 7-6.
Bencic had produced a string of performances at Wimbledon that resembled her 2016 form when she reached No 7 as a 19-year-old before injuries derailed her progress.
Wins over sixth seed Caroline Garcia and former world No 4 Carla Suarez Navarro made Bencic a tough prospect for Kerber, but the German proved a step too far for the 21-year-old Swiss.
