Maria Sharapova concedes just four more games on her way to reaching the last four of the Australian Open.

Maria Sharapova has advanced to the semi-finals of the Australian Open courtesy of a 6-2 6-2 victory over Ekaterina Makarova.

It took just 66 minutes for the four-time Grand Slam champion to set up a match with Li Na, who prevailed 7-5 6-3 over Agnieszka Radwanska.

Makarova made a confident start in holding her opening service game to love.

The world number two replied with a comfortable hold of her own, before getting her nose in front in the third game of the match.

The 24-year-old Muscovite became the first person to break the Sharapova serve in the tournament, hitting a spectacular forehand winner to get back on track.

However, a double fault when defending a break point in the next game gifted Sharapova another break.

Last year's beaten finalist continued her relentless march in Melbourne by breaking once more and serving out for a one-set lead.

Makarova was on her way to an easy hold of serve in the first game of the second set, but a loose shot allowed Sharapova back in.

The 25-year-old took full advantage of some slapdash shot selection to get the break.

She again secured the double break on her way to another straight-sets victory.
