Former world number one Maria Sharapova has revealed she failed a drugs test at the Australian Open. The Russian, 28, tested positive for meldonium, a substance she has been taking since 2006 for health issues. Sharapova, a five-time Grand Slam champion, is provisionally suspended from 12 March pending further action. "I did fail the test and take full responsibility for it," said Sharapova, who won the Wimbledon title as a 17-year-old in 2004.
