Agnieszka Radwanska won the WTA Finals in 2015

Wimbledon finalist Agnieszka Radwanska has announced her retirement from tennis at the age of 29.

The former world number two was runner-up to Serena Williams in 2012 and won 20 WTA titles in her 13-year career.

She finished every season between 2008 and 2016 ranked inside the world's top 15, but is currently ranked 75th and has not won a title since October 2016.

Radwanska said the decision to retire was "one of the most important" of her life and was "not easy".

"Unfortunately I am no longer able to train and play the way I used to, and recently my body can't live up to my expectations," she added.

"Taking into consideration my health and the heavy burdens of professional tennis, I have to concede that I'm not able to push my body to the limits required."
