Five-time Grand Slam champion Maria Sharapova is "saying goodbye" to tennis at the age of 32.
In an article written for Vogue and Vanity Fair, Sharapova said her body "had become a distraction" after a struggle with shoulder injuries.
The Russian won her first Grand Slam at Wimbledon in 2004 aged 17 and completed the career slam - all four major titles - by winning the French Open in 2012.
In 2016, she served a 15-month ban after testing positive for meldonium.
After returning from her ban in 2017, Sharapova struggled to recapture her best form and suffered from a number of injuries.
She has dropped to 373 in the world, her lowest ranking since August 2002, and has lost in the first round of her past three Grand Slam tournaments.
Sharapova said her 6-1 6-1 first-round defeat by Serena Williams at last year's US Open was the "final signal".
Sharapova did not play again in 2019 after that defeat at Flushing Meadows and has played just twice this year, including a straight sets loss to Croat Donna Vekic in the Australian Open first round, her last competitive appearance.
