Having failed to win 5 match points in her semi-final match in the 2013 Australian Open Azarenka took a 'medical' time out. In the on-court interview after the match she said she did this to steady her nerves but in the press conference afterwards she changed her story by saying it was for a back problem. A medical time-out is only allowed for 'a serious medical condition' and it appears that players are not allowed to take one just to steady their nerves. Maybe they should?! Was this cheating?
Azarenka eventually won the match, advancing to the final, where she beat Li Na. No action was taken against her for her unorthodox time-out.
