Nicole Vaidisova not only continued her hot streak, she also prolonged Russian Nadia Petrova's search for an elusive title.

The second seed from the Czech Republic, Vaidisova claimed her third consecutive title with a 6-1 6-7 (5/7) 7-5 victory over the top-seeded Petrova in the final of the PTT Thailand Open on Sunday.

Successfully following back-to-back titles at Tokyo and Seoul, the 16-year-old Vaidisova captured her 15th consecutive win. Her last loss was a setback in straight sets to Petrova in the fourth round of the US Open in their only previous meeting.

With the win, Vaidisova joined exclusive company, becoming just the sixth woman to claim five career WTA Tour titles before her 17th birthday, joining Tracy Austin, Andrea Jaeger, Monica Seles, Jennifer Capriati and Martina Hingis.

Playing in her fourth career final, Petrova once again came up short.

Ranked ninth in the world, Petrova is the only player within the top 20 without a title.
