Maria Sharapova appealed her two-year doping ban Tuesday to the Court of Arbitration for Sport, the highest court in sports, seeking to overturn or reduce the suspension imposed by the International Tennis Federation after the 29-year-old Russian tennis star tested positive for meldonium at the Australian Open in January, taking it before each match even though the substance was banned at the start of 2016. Both sides agreed to an ‘‘expedited procedure’’ that will allow the court to issue its ruling by July 18, at the latest, which, in the event of a favorable outcome, would allow Sharapova to be eligible to compete at the Olympic Games in Rio de Janeiro. Sharapova’s ban is due to end on Jan. 25, 2018, which would keep her out of eight Grand Slam tournaments along with the Olympics.
