Russian 12th seed Elena Dementieva let a comfortable lead slip on Monday and beaten 3-6, 6-2, 6-3 by 16-year-old Tamira Paszek in a rain-interrupted third round match at Wimbledon.
They had started the match on Saturday when just over an hour's play was possible before rain halted play with only two matches completed that day.
After two nights to sleep on her lead, Dementieva did not seem to wake up and allowed the young Austrian to take control from the start.
Fellow-Russian and fifth seed Svetlana Kuznetsova had no such problems, needing just two games on Monday to seal a 6-2, 6-3 victory over Poland's Agnieszka Radwanska.
Sixth seed Ana Ivanovic, runner-up at the French Open last month, also quickly wrapped up a 6-3, 6-2 win over Aravane Rezai of France to book her place in the fourth round.
Three-times former champion Venus Williams, seeded 23, dropped a set on resumption and had to battle back to beat Akiko Morigami of Japan 6-2, 3-6, 7-5 to set up a mouthwatering fourth round tie with second seed Maria Sharapova.
Eleventh seed Nadia Petrova of Russia was also pushed hard in the second set of her resumed match against Spaniard Virginia Ruano Pascual but eventually won 6-3, 7-6.
Nicole Vaidisova, the Czech 14th seed, rattled off three games after restarting her match against Belarussian Victoria Azarenka to win 6-4, 6-2.
