Second seed Svetlana Kuznetsova pulled her game together just in time edging to a 7-6, 6-2 win over Tsvetana Pironkova of Bulgaria in the second round.
Pironkova, ranked 92 places behind her opponent at 94th in the world, had a set point in the ninth game but the Russian hit back to clinch a place in the last 32.
"I didn't start well, definitely, and I was messing it up, and she was playing pretty good," the Russian said.
