Sharapova targets Brisbane success

World number four Maria Sharapova is confident of adding to her trophy cabinet when she makes her comeback from injury at the Brisbane Invitational.

Although six of the world's top 10 players will be competing at the Australian Open warm-up event - including the world's top player Serena Williams - the Russian pinup is confident of a positive result in her first tournament since undergoing shoulder surgery in August.

"I feel like I have had a really good off season," she said.

"I have started way ahead of schedule.

"It is just really fun for me to be back on court - I have certainly missed it."

The four-time Grand Slam winner recently played an exhibition match against former world number one Ana Ivanovic in Bogota - which she lost in three sets - but the 26-year-old knows all too well that warm-up matches aren't all they are cracked up to be.

In only one of the 10 Australian Opens she has competed in has she played a full tournament ahead of the year's first Grand Slam title, but has reached the final thrice - including winning ones - and reached the last four on three more occasions

"I love this game. I have achieved a lot but I feel I have a lot left in me," she continued.

"There are a lot more to do in the grand slams but events like these are quite important.

"It's the lead-up to the big ones that you want to capture.

"I can't wait to get on the court."

This year's Brisbane Invitational starts on Sunday, December 29.
