Wozniacki to retire after Australian Open

Former world number one Caroline Wozniacki announced on Friday that she will retire after next month's Australian Open, insisting she "has accomplished everything" she wanted on a tennis court.

The 29-year-old Dane won her only Grand Slam singles title in Melbourne last year in her third major final.

"I've accomplished everything I could ever dream of on the court," she said in an Instagram post.

"I've always told myself, when the time comes, that there are things away from tennis that I want to do more, then it's time to be done."

Wozniacki, who turned professional at the age of 15 in 2005, spent 71 weeks at the top of the WTA rankings after first becoming the world's best player in October 2010.
