LONDON, June 30 (Agencies): Caroline Wozniacki suffered a shock straight-sets exit as unseeded Barbora Zahlavova Strycova picked up her second big Wimbledon scalp to reach the quarter-finals.
Zahlavova Strycova, the world No.43, sent second seed Li Na packing on Friday and followed it up with a 6-2, 7-5 win over 16th seed Wozniacki on Court 12.
Wozniacki clawed her way back on serve in the second set after suffering an early break and then fought off two match points at 5-4 down to hold.
Zahlavova Strycova wasted a third match point on Wozniacki�s next service with a wide return before the Dane dug in to defend a fourth and a fifth.
However, Wozniacki then double faulted before planting a backhand wide to hand Zahlavova Strycova the win after 95 minutes.
Elsewhere, Lucie Safarova beat Tereza Smitkova 6-0 6-2 to reach her first grand slam quarter-final since the 2007 Australian Open, where she upset defending champion Amelie Mauresmo.
She�ll face Agnieszka Radwanska or Ekaterina Makarova next.
Earlier on Monday, Madison Keys withdrew from her to-be-finished match against Yaroslava Shvedova due to a left-thigh injury. Shvedova moved into the fourth round 7-6(7) 6-6 ret. and will face Sabine Lisicki or Ana Ivanovic.
