Russian tennis player Maria Sharapova speaks at a press conference in downtown Los Angeles, California, March 7, 2016. The former world number one announced she failed a doping test at the Australian Open, saying a change in the World-Anti-Doping Agency banned list led to the violation. Sharapova said she tested positive for Meldonium, a substance she had been taking since 2006 but one that was added to the banned list this year. / AFP / ROBYN BECK
