Naomi Osaka is now the highest-paid female athlete in 22, earned $37.4 million in the past 12 months from prize money and endorsements, which is $1.4 million more than Serena Williams made.

The money Osaka has earned has put an end to Williams 4 year streak as the world’s highest-paid female athlete.

“To those outside the tennis world, Osaka is a relatively fresh face with a great back story,” David Carter, a sports business professor at USC’s Marshall School of Business tells Forbes.

“I’m really interested in seeing a young business grow and adding value to that process,” Osaka told Forbes last year.

Osaka spoke to Forbes about her most recent marketing campaign with Bodyarmor that was just launched last week, “I always look outside tennis to see how other athletes are training and conducting themselves,” she says.
