Maria Sharapova admits failing dope test

Five-time Grand Slam tennis champion Maria Sharapova said on Monday she failed a dope test at the Australian Open, and isn’t sure what punishment she’ll face for her “huge mistake.”

The former world number one from Russia said a change in the World Anti-Doping Agency’s banned list for 2016 led to an inadvertent violation, for which she will be “provisionally suspended” by the International Tennis Federation.

In a sign of what the affair could mean to Sharapova’s mass of money-spinning endorsements, US sportswear maker Nike said it was “saddened and surprised” by the news.

“We have decided to suspend our relationship with Maria while the investigation continues.”

Sharapova tested positive for Meldonium, a drug she said she had been taking since 2006 but was only added to the banned list this year.

“I did fail the test and I take full responsibility for it,” Sharapova said at a press conference at a downtown Los Angeles hotel.

“I made a huge mistake. I let my fans down. I let my sport down that I’ve been playing since the age of four that I love so deeply,” added Sharapova, her voice wavering. “I know that with this, I face consequences and I don’t want to end my career this way — and I really hope I will be given another chance to play this game.”

The ITF confirmed in a statement that Sharapova had tested positive on January 26 and had accepted the finding when she was notified on March 2.

“Ms Sharapova will be provisionally suspended with effect from 12 March, pending determination of the case,” the ITF said.

Sharapova, 28, burst onto the international scene as she giggled and grunted her way to the Wimbledon crown in 2004. She won the US Open in 2006, the Australian Open in 2008 and the French Open in 2012 and 2014.

Her ferocity on the court, business acumen and glamorous looks have all combined to make her a marketing juggernaut and the overseer of such successful ventures as her Sugarpova line of candy.

She has 35 WTA singles titles, more than $36 million in career earnings and is currently ranked seventh in the world.

Sharapova said she originally began taking Meldonium for a variety of symptoms, including a tendency to become ill often, an irregular EKG heart test and a family history of diabetes.

Meldonium is used to treat heart trouble, including angina and heart failure. In adding it to the banned list, the Wada said there was evidence it has been used by athletes with the intention of enhancing performance.
