Sloane Stephens
At the age of 27, Sloane Stephens remains a formidable tennis player. She is one of the best players from the United States at the moment. She was No. 3 in the world after winning the US Open and then Wimbledon. It goes without saying that this is still the early days of her career, which makes her even more impressive. She currently has a net worth of $15 million even though she has only made $8 million from her sports career. This has to do with her sponsorships with Under Armour. Her parents are both athletic, so it was a given that she would pick up their love of sports. She was already making waves in the Australian Open by the time that she was 19 years old!
Simona Halep
This Romanian tennis player has definitely come a long way since the beginning of her career. Simona Halep has been named No. 1 in the world two times, but she has not stopped there. She has not slipped lower than the fourth spot since 2014. Not many people can claim the same thing. Apart from her achievements in sports, she signed a contract with Under Armour in February 2018. The deal is worth $1.7 million! In the past, she has worked with Lacoste, Adidas, and Mercedes-Benz Romania. Her career earnings have a total of $33 million, but she is currently worth $30 million.
