Australian Open: Safarova and Vaidisova through to quarter final

Lucie Safarova gave a stunning victory against defending champion Amelie Mauresmo of France in the fourth round of the Australian Open on Sunday. The 19 year old Czech who ranks 70th in the world will play Nicole Vaidisova, seeded 10th, in the quarter-finals. Vaidisova defeated Russian seventh seed Elena Dementieva to become the highest-ranked player in that half of the draw. It will be the first all-Czech women's quarter-final in a grand slam since Denisa Chladkova played Jana Novotna at Wimbledon in 1997.

In the men's third round matches carried over from Saturday's rain suspensions, Czech 13th seed Tomas Berdych - Safarova's boyfriend - overcame Russian Dmitry Tursunov and will face third seed Nikolay Davydenko on Monday.
