Two-time Australian Open champion Victoria Azarenka advanced to the third round of the US Open on Thursday by defeating Canada's Aleksandra Wozniak 6-3, 6-1.
Belarus second seed Azarenka moved into a matchup against French 26th seed Alize Cornet for a berth in the last 16.
Azarenka, who had 16 winners and 19 unforced errors, improved to 3-0 in top-level matches against Wozniak, who until this week had played only two matches in the past 12 months because of a right shoulder injury.
"I'm glad I got the first set," Azarenka said. "I was able to force the rhythm better in the second set."
