TORONTO (AP)—Flavia Pennetta defeated Urszula Radwanska 6-3, 3-6, 6-2 Monday to advance to the second round of the Rogers Cup in Toronto.

Mona Barthel edged Jie Zheng 6-7 (3), 6-3, 7-6 (1).

American Bethanie Mattek-Sands entered the tournament as a "lucky loser'' when Britain's Laura Robson pulled out because of a right wrist injury. Yanina Wickmayer defeated Mattek-Sands, 6-4, 2-6, 6-4.

Robson was coming off a strong performance at Wimbledon where she reached the fourth round — the first British woman to do so since 1998.
