Former world number one Caroline Wozniacki (29) announced that she will retire from tennis after 2020 Australian Open.

Dane won her only Grand Slam singles title in Melbourne last year. 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.

She has won 30 WTA titles so far in her career, including the 2017 Tour Finals in Singapore.

Wozniacki, who finished 11 straight seasons in the world top 20, is currently ranked 37th after struggling with injuries and poor form in 2019, reaching only one final.
