The Polish sisters advanced into the third round with the wins, which included Urszula's surprising 6-4, 6-2 upset of second-seeded former Wimbledon runner-up Marion Bartoli of France.

Meanwhile, 23-year-old Agnes Radwanska breezed past Ukrainian lucky-loser Lesia Tsurenko 6-1, 6-0 in 56 minutes. She'll next face Belgian wild card Alison Van Uytvanck, who bested South African Chanelle Scheepers 4-6, 6-4, 6-2.
