BIRMINGHAM, England -- Belgian 18-year-old Yanina Wickmayer earned her second straight victory over a seeded player, defeating No. 8 Michaella Krajicek 6-3, 6-4 on Thursday at the DFS Classic, to reach her first WTA Tour quarterfinal.
Two weeks after playing in her first Grand Slam and drawing the praise of recently retired compatriot Justine Henin, Wickmayer reached the last eight in only her fourth event on the main women's tour.
In other matches Thursday, No. 3 Nicole Vaidisova wasted a 4-1 lead in the first set and had to rally for a 6-7 (5), 6-2, 6-4 victory over Ekaterina Marakova.
The other remaining seeds are the Bondarenko sisters from Ukraine, both of whom had to come from behind to reach the quarterfinals and set up a sibling showdown in the semis if they both win one more match.
