Kirilenko was strong in the first set, dropping just one game, but wasn't able to put away Carla Suarez Navarro until the 10th game of the third set. She won at 6-1, 4-6, 6-4 and made the tournament quarterfinals.
Her opponent in the next round will be Edin Gallovits, the KIA runner-up in 2007. Gallovits was sharp again Thursday, dispatching Klara Zakopalova 6-2, 6-0.
