The world No 344, two spots below her opponent, jumped to a 5-3 lead in the final set before Dzalamidze, winner of an ITF Circuit in Hua Hin last year, broke back in the next game. The Thai finally wrapped up the encounter on her second match point in the 10th game on the Russian serve after two hours and 35 minutes to reach her first quarter-final since Mumbai in December.
The 25-year-old from Chiang Mai will wait for a winner between Fourth seed Lu Jia Jing of China or Ayano Shimizu of Japan.
