U.S. Open champion Kim Clijsters is through to the quarterfinals of the Montreal Cup after crushing Kaia Kanepi of Estonia for the loss of just three games on Thursday.
The Belgian -- who collected her third WTA Tour victory of the season in last week's Cincinnati event -- took less than an hour to secure a 6-2 6-1 victory.
The fifth seed now takes on Russian eighth seed Vera Zvonareva for a place in the semifinals.
"It's a bit of an adjustment, playing under the lights at night and then today in the heat, but I'm pleased the way I played," Clijsters, who has now won her last 14 matches on summer hardcourts, told the official WTA Tour website.
"It's always nice to win a tournament and gradually feel your level improve," she added.
New world number two Caroline Wozniacki is also into the last eight -- but she had to recover from dropping the opening set before dispatching Flavia Pennetta of Italy 4-6 6-3 6-1.
The Dane now plays Pennetta's compatriot and French Open champion Francesca Schiavone, who saw off former world number one Dinara Safina 6-4 6-3.
Former French Open champion Svetlana Kuznetsova will take on China's Zheng Jie, who shocked another Russian -- fourth seed Elena Dementieva -- 6-4 1-6 6-3 to reach the last eight in Canada.
The final quarterfinal will be between France's Marion Bartoli, who outclassed top seed Jelena Jankovic's conqueror Iveta Benesova, and Victoria Azarenka of Belarus.
