St. Petersburg, FL -- (Sports Network) - Former Top-10 player Alicia Molik has announced her retirement from professional tennis.

The 27-year-old Aussie had her career derailed by an inner ear infection in the spring of 2005. The problem, which affected her vision and balance, knocked her out of the sport for almost a year.

After two years of trying to fight her way back to the upper echelon of the game, Molik called it quits this week after battling a series of injuries over the past couple of years.

"It's tiring and it's very draining but I guess it's a number of things culminating," Molik said. "I've spent a lot of time thinking. I did have a huge setback three years ago, with my middle ear problem. It took a while to get back, and since then I've just struggled with a few more things that I never imagined would come along the way. But that isn't the only thing. I think I'm still young enough to focus my energies on something that I feel is again challenging."

In 2004, Molik won three WTA events and a bronze medal at the Olympic Games in Sydney. The next season, Molik became the first Aussie woman in more than 20 years to crack the Top-10.

Molik's singles career on the circuit was highlighted by five titles and the aforementioned bronze medal. She was also a Top-10 player in doubles, winning seven titles, including two majors. Molik reached three Grand Slam mixed doubles finals and represented Australia in Fed Cup play for eight years and at three Olympic Games (2000, 2004, 2008).
