Second-seeded 2012 runner-up Maria Kirilenko highlighted Friday's quarterfinal winners at the hardcourt Pattaya Open.
Kirilenko handled seventh-seeded fellow Russian Elena Vesnina 7-6 (8-6), 6-3 at Dusit Thani Hotel.
The 25-year-old Kirilenko, who lost to Slovakian Daniela Hantuchova in last year's championship match here, will face fourth-seeded Romanian Sorana Cirstea in Saturday's semifinals. Cirstea advanced by easily besting Latvian qualifier Anastasija Sevastova 6-3, 6-0 on Day 5.
The other semi will pit fifth-seeded German Sabine Lisicki against Russian Nina Bratchikova. Lisicki overcame New Zealand's Marina Erakovic 5-7, 6-3, 6-2, while Bratchikova held off Japanese Ayumi Morita 6-1, 3-6, 6-1.
This week's titlist will collect $40,000.
