China's world number six Li Na overpowered Sesil Karatantcheva of Kazakhstan 6-1, 6-3 to reach the Australian Open second round.

Li, the runner-up two years ago at Melbourne Park, established herself early in each set as she went through in 1hr 18min to set up a match with France's Pauline Parmentier or Olga Govorstova of Belarus.

The 2011 French Open winner belted a deep forehand winner to claim the first game and she seized control by breaking for 3-1 and then 5-1, taking the set with ease.

Karatantcheva made her work harder for the second set but her resistance ultimately proved futile as Li sealed her progression with a forehand winner.
