Eighth-seeded Vania King advanced to the quarter-finals of the Pattaya Open by beating Alla Kudryavtseva of Russia 6-1, 6-3 yesterday.
The American played well from the baseline to beat her friend and reach the quarter-finals for the first time since September last year in Seoul.
“I didn’t play many international events after Seoul,” King said.
“I spent most of my offseason trying to recover fully and try not to get injuries, which was something I was struggling with in the past few years,” she said.
King will next play defending champion Daniela Hantuchova of Slovakia, who beat Urszula Radwanska of Poland 6-3, 6-2 in a match that was briefly suspended by light rain before the end of the first set.
Sania Mirza also advanced to the quarter-finals by beating Anne Keothavong of Britain 6-4, 7-5.
Mirza, who lost the 2009 final to Vera Zvonareva, will play Taiwanese qualifier Hsieh Su-wei.
Hsieh defeated Japanese veteran Kimiko Date-Krumm 7-5, 6-0.
