Los Angeles: Russian tennis ace Maria Sharapova on Monday admitted to failing a drug test at the Australian Open in January, an act that will get her suspended from tennis, BBC reported.

Sharapova, in a press conference in Los Angeles on Monday, said she had been taking the drug, meldonium, ever since 2006 and didn't realise that it became a banned substance by the World Anti-Doping Agency (WADA) at the start of 2016.
