Maria Sharapova has announced her retirement from tennis at the age of 32.
The former world number one revealed her decision in the form of 'exclusive' articles for both Vogue and Vanity Fair magazines, which both carried an essay titled: 'Tennis - I'm saying goodbye'.
Sharapova, who won five Grand Slam singles titles, has struggled with injuries and has now decided to end her career ahead of the clay-court season.
The final match of her career proved to be her Australian Open first-round clash with Donna Vekic, which she lost 6-3 6-4, back in January.
"How do you leave behind the only life you've ever known?" she wrote in Vogue.
"How do you walk away from the courts you've trained on since you were a little girl, the game that you love - one which brought you untold tears and unspeakable joys - a sport where you found a family, along with fans who rallied behind you for more than 28 years?
" I'm new to this, so please forgive me. Tennis - I'm saying goodbye."
"In giving my life to tennis, tennis gave me a life. I'll miss it every day."
Steve Simon, CEO of the Women's Tennis Association, told the New York Times: "Maria is very smart, very savvy, very professional, probably the ultimate professional.
"She'll be remembered very well for what she brought to the game and I think everybody thinks of her as the ultimate competitor."
Sharapova clinched a career Grand Slam when she triumphed at Roland-Garros in 2012 and became one of only 10 women to have achieved the feat.
The Russian won Wimbledon in 2004, the US Open in 2006 and the Australian Open two years later. She then secured two Roland-Garros crowns in 2012 and 2014.
She has struggled with injuries and poor form since returning from a 15-month drugs ban in 2017, the result of testing positive for meldonium at the 2016 Australian Open.
