Urszula Radwanska swept aside Vitalia Diatchenko of Russia in straight sets to reach the quarterfinals of the Tashkent Open on Wednesday.
Radwanska, the younger sister of third-ranked Agnieszka, used a strong serve to beat the 394th-ranked Diatchenko 6-2, 6-2. After struggling in her opening round match, the 40th-ranked Radwanska broke Diatchenko three times in the first set and twice in the second set on her to an easy win.
She was joined in the last eight by fifth-seeded Alexandra Cadantu of Romania, who beat Sabina Sharipova of Uzbekistan 1-6, 6-3, 6-3.
Sixth-seeded Bojana Jovanovski converted her fourth match point to beat Eleni Daniilidou of Greece 6-3, 6-7 (8), 6-3, while seventh-seed Alexandra Panova of Russia beat Misaki Doi of Japan, 6-4, 6-4. Eighth-seeded Galina Voskoboeva of Kazakhstan ousted Anna Chakvetadze of Russia 6-1, 6-3.
Croatian 16-year-old qualifier Donna Vekic, who knocked out fourth-seeded Magdalena Rybarikova on Tuesday, downed Lara Arruabarrena-Vecino of Spain, 6-2, 6-2 to reach her first WTA quarterfinals.
''It's an amazing feeling. I'm absolutely thrilled,'' Vekic said. ''The points are important but developing my game and as an athlete is more important for me in the next few years.''
The only upset of the day was from Irina -Camelia Begu of Romania, who beat third-seeded Alize Cornet of France 6-4, 6-1 in just under two hours. Begu broke Cornet to win the first set and twice broke the poor-serving Frenchwoman in the second to reach her third quarterfinal of the year.
''I know Alize's game as we have played doubles with each other before so I played patiently,'' Begu said. ''I managed to return well today. In the second set, I started hitting very well and the scores changed.''
