Moscow-born Vesna Dolonc of Serbia won a main-drawn match for the first time since Wimbledon when she beat eighth-seeded Yaroslava Shvedova of Kazakhstan 7-6 (8/6), 7-5 in the first round of the Tashkent Open yesterday.

No. 7-seeded Galina Voskoboeva of Kazakhstan became the sixth and last of the eight seeds to make the second round when she defeated Maryna Zanevska of Ukraine 6-3, 6-4.
Julia Glushko of Israel, Petra Cetkovska of the Czech Republic, Maria-Teresa Torro-Flor of Spain and Misaki Doi of Japan also reached the second round yesterday.
On Monday unseeded Nastassja Burnett of Italy advanced to the second round by beating second-seeded Lesia Tsurenko of Ukraine 7-6 (7/4), 6-4.
Third-seed Yvonne Meusburger of Austria defeated Timea Babos of Hungary 2-6, 6-2, 6-1 on Monday, while top-seeded Bojana Jovanovski of Serbia, fifth-seeded Alexandra Cadantu of Romania, and sixth-seeded Irina-Camelia Begu of Romania also advanced.
