The women's world number three seed Victoria Azarenka of Belarus is the first player to advance to the quarter-finals of the Australian Open tennis championship in Melbourne.
The in-form Azarenka chalked up her fourth successive straight sets victory, beating Iveta Benesova from the Czech Republic 6-2 6-2 in a match lasting one hour and 17 minutes.
Azarenka has now equalled her best-ever performance at an Australian Open, having also previously reached the last eight in 2010.
She is riding a nine-match winning streak this year after previously winning the Sydney International.
Azarenka now advances to a quarter-final against either Agnieszka Radwanska from Poland or Julia Goerges from Germany.
