World No.1 Serena Williams earned $6.5 million in 2009, which is the largest amount of prize money ever earned in women’s tennis during a single season.
Williams won two Grand Slam titles in 2009 – Australian Open and Wimbledon – and finished the successful year in style by earning the season-ending No.1 ranking and winning the Sony Ericsson Championships.
Previously, Justine Henin held the record with her slightly under $5.5 million earned in 2007.
