NEW YORK - Maria Sharapova may not have won a grand slam title since 2008, but the Russian tennis player remains unchallenged as the world's highest paid woman in professional sports.
Sharapova's earnings, mostly off-court endorsements, were estimated at $25 million, twice as much as her nearest rival, Denmark's Caroline Wozniacki, the current women's world number one.
American racing driver Danica Patrick was third with $12 million followed by tennis players Venus Williams, Belgium's Kim Clijsters and Serena Williams.
Seven of the top nine female earners were tennis players, including China's Li Na, who made $8 million last year but was expected tosoar up the rankings and challenge Sharapova for the top spot after her breakthrough win at the French Open.
