Paris, France (AFP) — Five-time Grand Slam winner Maria Sharapova, one of the world’s most recognisable and highest-paid sportswomen, on Wednesday announced her retirement at the age of 32, and was immediately hailed as “a legend” and “great champion.”

“Tennis — I’m saying goodbye,” Sharapova said in an article for Vogue and Vanity Fair magazines.

“After 28 years and five Grand Slam titles, though, I’m ready to scale another mountain — to compete on a different type of terrain.”

Men’s number one Novak Djokovic dubbed Sharapova a “legend” of the sport, hailing her “great impact”.

“She’s a very smart girl. She has the mind of a champion, someone that never gives up,” said Djokovic.

Sharapova burst onto the scene as a supremely gifted teenager and won her Grand Slams before serving a 15-month ban for failing a drugs test at the 2016 Australian Open.

The Russian former world number one’s ranking is currently 373rd.

Sharapova has hardly played in the past year because of long-standing shoulder problems.

When she did feature she lost as many matches as she won and was dumped out in the first rounds at Wimbledon, the US Open and, most recently, the Australian Open in Melbourne.

Siberian-born Sharapova first picked up a racquet at the age of four in Sochi, where her Belarus-born parents had settled after escaping the deadly clutches of the 1986 Chernobyl disaster.

She shot to fame as a giggly 17-year-old Wimbledon winner in 2004, the third-youngest player to conquer the All England club’s hallowed grass courts.

Tennis gave me life

She became world number one in 2005, at the age of 18, and won the US Open the next year.

“One of the keys to my success was that I never looked back and I never looked forward,” Sharapova said on Wednesday.

“I believed that if I kept grinding and grinding, I could push myself to an incredible place.”

But in 2007 Sharapova began her long on and off battle with shoulder trouble.

She would win the 2008 Australian Open before a second shoulder injury kept her off tour for the second half of the season, missing the US Open and Beijing Olympics.

In 2012, the Siberian-born Sharapova captured the French Open to become the 10th woman to complete a career Grand Slam. She added Olympic silver to her resume that year.

Her 2014 French Open title was another high, after a dispiriting injury low.

More fitness troubles followed before the bombshell announcement of her positive test for the banned heart drug meldonium.

Always a fighter

Always a fighter — the seven-year-old Maria and father Yuri left for the US in 1994 with just a borrowed US$700 to their names — Sharapova returned to the sport in 2017.

“In giving my life to tennis, tennis gave me a life,” Sharapova said in her retirement missive.

“I’ll miss it everyday. I’ll miss the training and my daily routine — waking up at dawn, lacing my left shoe before my right, and closing the court’s gate before I hit my first ball of the day.

“I’ll miss my team, my coaches. I’ll miss the moments sitting with my father on the practice court bench. The handshakes — win or lose — and the athletes, whether they knew it or not, who pushed me to be my best.

“Looking back now, I realise that tennis has been my mountain. My path has been filled with valleys and detours, but the views from its peak were incredible.”

Sharapova had been the highest-paid female athlete in the world in the 11 years up to 2016, according to Forbes business magazine.

She netted prize money alone of US$38.8 million (35.7m euros) in a career during which she won 36 singles titles. Forbes, in its 2016 article, said the Florida-based Russian had banked nearly $300m from prize money, appearances and endorsements since she turned professional in 2001.

She has also established herself as an entrepreneur, launching her own line of candy, ‘Sugarpova’, and warned Wednesday her “relentless chase for victories…won’t ever diminish”.

“No matter what lies ahead I will apply the same focus, the same work ethic, and all of the lessons I’ve learned along the way.

“In whatever I might choose for my next chapter, my next mountain, I’ll still be pushing, I’ll still be climbing. I’ll still be growing.”

Sharapova’s Coach Riccardo Piatti tweeted “It’s been an honour to have worked with such an amazing athlete and person. I’ll miss her on court and outside.”

Olympic champion Monica Puig praised Sharapova for helping in relief efforts when Puerto Rico was devastated by a hurricane in 2017.

“Thanks for being such a great friend and a true example of what a champion really is. I wish you nothing but the best. You deserve it,” she tweeted.
