Naomi Osaka shocked the tennis world last week after capturing her first Grand Slam win by defeating Serena Williams in the U.S. Open finals. Now, the 20-year-old Japanese-Haitian star could be destined for another first to the tune of $8.5 million per year.

That’s how much Adidas is prepared to pay the young star, according to The Times of London. If the endorsement materializes as planned, it would be the biggest deal Adidas has ever given to a woman. Osaka’s current contract with the Three Stripes, which is set to expire this year, is reportedly in the neighborhood of six figures. Osaka has been steadily climbing the women’s tennis rankings since 2017, and her win over Williams on Saturday made her the first Japanese-born player to take home a major title.
