Serena Williams had a fantastic run at the Australian Open tennis tournament, the winner in both singles and in doubles with her sister Venus. Which took Serena back to No. 1 in the official tour rankings.
Even more good news for Serena is she has become the leading woman, in any sport, in career earnings. As you can see from the chart, the Williams family dominate in career earnings.
Our second chart shows the extent of change in earnings for women sports stars over the years. Navratilova won 30 times more matches in her impressive career than Serena has so far.
