Martina Hingis has tested positive for cocaine use during the summer’s Wimbledon championship. As a result she’s announced her second retirement from competetive tennis.

Martina Hingis said yesterday that she has been
accused of testing positive for cocaine at Wimbledon, and then
announced her retirement from professional tennis.

Hingis, a five-time Grand Slam champion and former Wimbledon winner, denied using cocaine.

"I find this accusation so horrendous, so monstrous that I’ve decided
to confront it head-on by talking to the press," she said. "I am
frustrated and angry. I believe that I am absolutely, 100 percent
innocent."

Hingis said that she had privately taken a hair test (you can track drug use by looking at the hair that was actually growing in the follicle at the time of the alleged use) which showed that she had not in fact been using the drug:

"I have tested positive but I have never taken drugs
and I feel 100 per cent innocent," said Hingis, who was also the
youngest Wimbledon champion in the professional era when she won as a
16-year-old in 1997. At this summer’s Wimbledon, she lost in the third
round to American Laura Granville.

"The reason I
have come out with this is because I do not want to have a fight with
anti-doping authorities. Because of my age and my health problems I
have also decided to retire from professional tennis."

Her
management company later put out a statement, explaining that Hingis
viewed the allegation against her as "so horrendous, so monstrous, that
I have decided to confront it head-on by talking to the press. I would
personally be terrified of taking drugs. When I was informed, I was
shocked and appalled."

Hingis also revealed that,
after being told she had tested positive for cocaine, she decided to
have a dope test done privately. Hingis said that test was negative,
and so she has taken legal advice about how to clear her name.
