Russians Ksenia Pervak and Alla Kudryavtseva led the charge into Friday's semifinals at the $220,000 Tashkent Open.

The top-seeded Pervak pasted helpless French qualifier Victoria Larriere 6-1, 6-2 in exactly one hour, while the sixth-seeded and reigning Tashkent champion Kudryavtseva dismissed 2008 titlist Sorana Cirstea of Romania 7-6 (7-5), 6-4 Thursday on the hardcourts at Olympic Tennis School.

Pervak will meet Poland's Urszula Radwanska in Friday's semis, while Kudryavtseva will encounter Czech Eva Birnerova. Radwanska held off Greek Eleni Daniilidou 6-3, 4-6, 6-4, while Birnerova edged out Russian Valeria Savinykh 6-4, 4-6, 6-3 on Day 4.

Kudryavtseva beat Elena Vesnina in last year's all-Russian Tashkent finale.

The 2011 champion here will collect $37,000.
