TORONTO (AP) -- Canadians Stephanie Dubois and Aleksandra Wozniak advanced at the Rogers Cup tournament with first-round victories on Tuesday.
Dubois earned a 7-6 (4), 6-1 win over German qualifier Kathrin Woerle while Wozniak, from Blainville, Quebec, sailed past Israel's Shahar Peer 6-1, 6-0.
Serbia's Ana Ivanovic breezed past Chinese qualifier Shuai Zhang 6-1, 6-1. The 2006 champion hasn't advanced past the second round of the tournament since 2007.
In other action Tuesday: Roberta Vinci got past Yanina Wickmayer 6-4, 6-2; China's Shuai Peng eliminated Spain's Lourdes Dominguez Lino 6-1, 7-5; Spaniard Anabel Medina Garrigues topped Italy's Sara Errani 7-5, 6-1.
Serbia's Bojana Jovanovski won against Jelena Dokic after the Australian retired in the first set; Italy's Flavia Pennetta was a 6-3, 6-1 winner over Russia's Maria Kirilenko; and Slovakia's Daniela Hantuchova won 6-3, 6-4 over Argentina's Gisela Dulko.
Dubois, a wild card entry from Laval, Quebec, fought hard in the first set before taking control in the second. She hit a backhand slice to break Woerle for a 3-0 lead in the second.
Woerle put up resistance when down 4-0, fighting back to deuce several times and causing Dubois to smash her racket against the court in frustration before losing the game.
However, Dubois regained her composure to close out the match and earn a meeting with fourth-seed Victoria Azarenka of Belarus.
Eugenie Bouchard, however, wasn't able to join the Canadians in Round 2.
The 17-year-old wild card from Westmount, Quebec, lost 6-2, 6-2 to 10th-seeded German Andrea Petkovic after a rain delay of almost 3 1/2 hours.
