In March, the five-time Grand Slam champion announced that on January 26, she had tested positive for meldonium, a banned substance, while at the Australian Open.
He said he would not entrust ask his management to monitor what he took, either - as Sharapova has done with her agent, Max Eisenbud, who claimed he did not alert the player to a warning about the banned drug meldonium because he was holidaying during a personal crisis and did not see the emails from the International Tennis Federation.
"In her appeal to the CAS, Ms Sharapova seeks the annulment of the Tribunal's decision to sanction her with a two-year period of ineligibility further to an anti-doping rule violation", CAS said in a statement, adding that a decision would be made by July 18 at the latest.
A statement from Sharapova's lawyer said the ITF's ruling demonstrated that she "did not intend to violate the rules". Ms. Sharapova argues that any suspension is unwarranted since the ITF agrees with her that she accidentally broke the rules and wasn't trying to cheat.
"After reviewing the decision in full, including the reasoning that led to the Tribunal's decision, WADA today confirms that it will not be exercising its independent right of appeal to the Court of Arbitration for Sport (CAS)".
Russian star Maria Sharapova is getting no sympathy from Andy Murray over her failed drugs test. It has been suggested that the ITF were originally angling for a four-year ban, which would effectively spell an end to her career.
"If you're taking medication, there is absolutely no reason why you shouldn't know whether it's on the banned list or not". "Obviously there can be the odd case where, you know, if you were given something by a doctor, he tells you, oh, this is, I don't know, this is a vitamin, and it's not, you know, it's something completely different, then that's different".
