Former Top 5 player Anna Chakvetadze says she is unsure when she will return to the WTA. The 24-year-old Russian was beset with illness most of the past season. She is running as a candidate for Russia's Right Cause party in the forthcoming elections for the Duma. "This year was really a tough one for me," Chakvetadze told CNN. "There were several traumas and I decided to take care and restore my health. It doesn't mean that I'm over with my sport career. I just took a pause for an unknown period of time. So all my goals now are related with this party project."
