Brisbane, Australia (SportsNetwork.com) - Victoria Azarenka was an easy second-round winner Wednesday at the Brisbane International.

Azarenka, the 2009 Brisbane winner and runner-up in 2008, posted a 6-3, 6-1 victory over Australia's Casey Dellacqua. The native of Belarus will try for a third straight Australian Open title later this month. She also won two other tournaments in 2013 and was the U.S. Open runner-up.

Next up for Azarenka will be Switzerland's Stefanie Voegele, who advanced in a walkover. Seventh-seeded German Sabine Lisicki was unable to play because of a stomach illness.

Fifth-seeded Angelique Kerber of Germany also moved on when Russia's Anastasia Pavlyuchenkova retired in the second set with a left leg injury. Kerber had built a 6-2, 4-3 lead when Pavlyuchenkova, last year's Brisbane runner-up, called it quits.

The quarterfinals are on tap for Thursday.

In addition to the Azarenka-Voegele match, Kerber will meet fourth-seeded Serb Jelena Jankovic, top-seeded Serena Williams will take on Slovakia's Dominika Cibulkova and third-seeded Maria Sharapova will face Estonia's Kaia Kanepi, the 2012 Brisbane winner.
