| The former world number two was the first 
				Polish player to reach a Grand Slam singles final in the Open 
				Era, when she finished runner-up to Serena Williams at Wimbledon 
				in 2012.
 The 29-year-old, who finished with 20 WTA titles, was one of the 
				most consistent players on tour, finishing in top 10 rankings 
				for six straight seasons between 2011-2016.
 
 However, she has struggled for form and fitness over the recent 
				campaign and has not lifted a title since October 2016.
 
 "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," 
				Radwanska, 29, said in a post on Facebook.
 
 "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."
 
 In addition to her Wimbledon final appearance, Radwanska reached 
				the semi-finals of the Australian Open twice, and won the 
				season-ending WTA Finals in 2015.
 
 "I'm hanging the racquet up and say goodbye to the pro tour, but 
				I'm not leaving tennis," she added.
 
 "Tennis is and always has been special in my life. But now it's 
				time for new challenges, new ideas, equally as exciting as those 
				on the tennis court, I hope."
