With SI Swimsuit’s Net Worth Series: Empowering Equal Pay, our goal is to shine a light on incredible athletes while examining income disparities and promoting equal pay across industries.

Professional tennis player Sloane Stephens is renowned for her skills on the court. The 31-year-old athlete won the U.S. Open in 2017, and achieved a career-high ranking of world No. 3 following Wimbledon in ’18.

The one-time SI Swimsuit model, who posed for the 2018 issue in Aruba, is also incredibly successful off the court. She is the founder of the Sloane Stephens Foundation, an organization that aims to help underprivileged children through tennis and education.

“My professional career outside of tennis has been amazing,” she told the WTA last May. “I have been able to do incredible things, and a lot of the work and things behind the scenes I have been very proud of. I think that obviously with tennis being an 11-month sport it does limit you and the things you’re passionate about outside of tennis. I do think you have to make a lot of sacrifices in terms of whether it’s going to be tennis or your other passions and things that you want to do.”

Stephens participated in the U.S. Open in last month before falling in the first round and will participate in the Charlotte Invitational in December.

How did Sloane Stephens get her start?

Stephens was born into an athletic family, as her mother was a swimmer and her father was an NFL running back. The Florida native first picked up a tennis racket at the age of 9, and turned pro in 2009, when she was just 16. Since going pro, Stephens has won eight WTA Tour singles titles and competed in the 2016 Olympics in Rio.

“Even though tennis is an individual sport, you also are essentially the captain and CEO of your own little team, which when you’re just starting out can feel like so much, especially when you’re still figuring out who you are as a young person and learning to navigate life as a professional athlete,” Stephens told Teen Vogue of her outlook on her career as an athlete.
