Hailing one of the happiest days of her career, the Russian said she had learned a lesson from the “tough months” behind her and hoped the International Tennis Federation (ITF) and anti-doping authorities had also.
“In so many ways, I feel like something I love was taken away from me and it will feel really good to have it back,” the 29-year-old five-times grand slam champion said in a message to fans on her Facebook page.
“Tennis is my passion and I have missed it. I am counting the days until I can return to the court.”
Sharapova was handed the original ban, backdated to start on 26 January 2016, by the ITF following her positive test for the drug meldonium.
The arbitration panel ruled on Tuesday that she had committed an anti-doping rule violation for which “she bore some degree of fault”.
It added that the decision to reduce the ban concerned solely “the degree of fault that can be imputed to the player for her failure to make sure that the substance contained in a product that she had been taking over a long period remained in compliance with the anti-doping rules.”
Sharapova had called the ITF’s original ruling “unfairly harsh” as an independent tribunal had found that she had not intentionally violated anti-doping rules.
She admitted taking meldonium during the season’s opening grand slam in Melbourne but said she had been unaware that it had been banned by the World Anti-Doping Agency (WADA).
