Roberta Vinci routed former champion Ana Ivanovic 6-0, 6-0 Thursday at the Rogers Cup.
The 28th-ranked Vinci needed only 45 minutes to eliminate 12th-ranked Ivanovic and advance to the third round of the hardcourt tournament. Ivanovic won the Rogers Cup in 2006.
Carla Suarez Navarro upset Sabine Lisicki 3-6, 6-3, 6-4, while No. 10 Marion Bartoli advanced with a 6-1, 6-3 win over Shuai Peng.
Also, Aleksandra Wozniak upset No. 18 Jelena Jankovic 6-2, 6-3. The 55th-ranked Wozniak, who was 0-4 against Jankovic, dominated the baseline duel.
Jankovic has struggled this season, losing in the first round for the fifth time in her last six tournaments and for the 13th time this year.
Many top players have had trouble finding the lines while making the switch to hardcourts after a month on grass at Wimbledon and the London Olympics.
