World No. 1 Caroline Wozniacki joins 2011 U.S. Open champion Samantha Stosur and 2011 French Open Champion Li Na as the headliners to Australia's Sydney International in January. Na returns as the tournament's defending champion.
Wozniacki confirmed her place on Dec. 1. The 21-year-old Danish star will be competing in the season's first tournament for the fourth-consecutive year.
From Sports Australia:
"The Sydney International is the ideal preparation for the first Grand Slam of the year," Wozniacki said.
However, Wozniacki's highest finish was a three-set quarterfinal loss to American Serena Williams in 2009.
Wozniacki is coming off a 2011 season in which she added six WTA Tour titles to her name - Dubai, Indian Wells, Charleston, Brussels, Copenhagen and New Haven. She also made it to the semifinals of two Grand Slams - the Australian Open and the U.S. Open. She also ended her second-straight WTA season ranked at the top slot.
