Maria Sharapova is critical of the ITF’s reported changes to the Olympics eligibility rule. Tennisspace.com reported that the ITF has already decided to change its eligibility rules for the 2016 Olympics, doubling the number of Fed Cup ties players must make themselves available for the four-year period leading up to 2016. Currently, players only have to make themselves available for two ties in the two years preceding the Olympics. Sharapova has played two ties for Russia in 2011 and 2012, but in the past has said that being required to play in multiple Fed Cup ties makes it too difficult on the players' schedules.

"I’m disappointed," Sharapova told the press in Stuttgart. "I met with them one on Miami. They didn't listen to us at all."
