Victoria Azarenka sees off Aleksandra Wozniak

World number one Victoria Azarenka produced an efficient display to dismiss the threat of Aleksandra Wozniak in straight sets at the French Open.

Azarenka lost her serve twice - largely due to the seven double faults she delivered - but responded with four breaks of her own.

After 86 minutes on Court 1, Azarenka completed the 6-4 6-4 victory just as the light was beginning to threaten to suspend play.

The Belarusian will now face Slovakia's Dominika Cibulkova in the last 16.
