Russian tennis star Maria Sharapova aims to return to the No. 1 spot in the rankings after a solid season in 2012. Sharapova won the French Open this year to complete the career grand slam. ''Obviously, the goal is always to shoot for top spot and that's always
where you want to be and stay,'' Sharapova said. ''It's one thing to
reach the No. 1 ranking, another to keep it.'
