grand slam titles when she competes at the US Open in NY starting next week, earned twice as much off the court as any other female athlete.
In June, the Forbes rankings of the world's top 100 highest earning athletes did not feature a woman after Williams dropped out of the chart. A victory, which would be her record-setting 24th major championship, would net her $3.8 million - the biggest prize tennis history.
Even though she spent most of year adjusting to motherhood, Serena Williams is - according to Forbes - once again far and away the highest paid female athlete on Earth for the third straight year.
Williams, who returned to competition in March after giving birth last September, earned Dollars 62,000 in winnings over the past year but received USD 18.1 million from an endorsement portfolio unmatched among women in sports, Forbes said. Sindhu, along with retired race auto driver Danica Patrick are the only non-tennis players on the list.
