Her estimated $34.4 million haul landed her just behind Naomi Osaka ($57.3 million) and Serena Williams ($45.9 million) on Forbes' all-time list.

Coco Gauff topped the list with an estimated $30.4 million in earnings—becoming only the third woman to cross the $30 million a year mark, after Naomi Osaka and Serena Williams.

Osaka was unranked when she returned to the tour at the start of the year, and finished the year just outside the Top 50.
