Williams, who returned to competition in March after giving birth last September, earned $62,000 in winnings over the past year but received $18.1 million from an endorsement portfolio unmatched among women in sports, Forbes said.
According to an annual list, Williams, who is gearing up to equal Margaret Court’s record of 24 grand slam titles when she competes at the Aug. 27-Sept. 9 U.S. Open in New York, earned twice as much off the court as any other female athlete.
In the list which was dominated by tennis players, Caroline Wozniacki was announced second on the list with combined earnings of ($13 million) while reigning U.S. Open champion Sloane Stephens ($11.2 million) was third.
