Naomi Osaka clearly on the rise after winning US Open

Her first Grand Slam title may have been overshadowed by what happened between Serena Williams and a chair umpire, but Naomi Osaka's star is clearly on the rise after winning the US Open.

Osaka, the 20‑year‑old who beat Williams in straight sets in the New York final, has signed on as a brand ambassador for Nissan, a move that shows both her international appeal to fans and her value to advertisers. She said growing up, her dad drove a Nissan, so being able to be a brand ambassador now, it feels like she has come full circle.

The Washington Post says that Osaka is also reportedly about to land the biggest deal Adidas has ever given a female athlete ‑ possibly in the US$10 million range. That's on top of the US$3.8 million  she took home in prize money after topping Williams.
