Aleksandra Wozniak's quest to win a WTA Tour title in her home country will have to wait another year.

The Blainville native dropped a 6-4, 6-4 decision to Russia's Alisa Kleybanova in first-round action Tuesday at the Rogers Cup in Toronto. Wozniak's loss means that none of the four Canadians in the main draw advanced to the second round.

Wozniak, ranked 40th in the world, came in with the highest hopes of them all. But the 21-year-old was broken three times in the first set, winning just 52 per cent of her first-serve points along the way.

Another service break put Kleybanova ahead 3-2 in the second set. After Wozniak broke to tie the game 3-3, the 36th-ranked Kleybanova returned the favour to go back up a break, sealing Wozniak's fate.

"She plays a really aggressive ball, and it was hard for me to change the direction like I wanted," said Wozniak. "I think she just stepped up on the easy, short balls that I was giving her. She was taking advantage."

No Canadian woman has won the Rogers Cup since Faye Urban beat countrywoman Vicki Berner in the 1969 final.

"It's disappointing, for sure," said Wozniak. "This tournament is the one I want to win so bad. Hopefully one day's it's gonna be mine."

Wozniak and Toronto's Sharon Fichman later fell 1-6, 7-6 (5), 10-4 to Polish duo Klaudia Jans and Alicja Rosolska in first-round women's doubles action.

Wozniak insists she won't let her subpar performance in Toronto spoil what has been a strong season to date.

"I have to look ahead," said Wozniak. "I was (21st) in the world a couple of weeks ago, and there's so many big tournaments out there I can do really well in. I just have to have a good attitude and keep going forward."

Venus sent into orbit

Earlier Tuesday, unheralded Ukrainian Kateryna Bondarenko recorded the upset of the tournament thus far, knocking off third-seeded American Venus Williams 1-6, 7-5, 6-4 in a second-round stunner. Bondarenko, ranked 64th in the world, will now face either Agnes Szavay of Hungary or Agnieszka Radwanska of Poland in the third round.
