World No.1 Naomi Osaka has joined the Nike roster of athletes.
The announcement came just hours after Osaka was a guest as the LA Lakers took on the Golden State Warriors - and was spotted chatting to injured superstar LeBron James, another Nike athlete.
The pair had met previously, just after Osaka's triumph at the US Open.
"Naomi is an incredible talent to add to our roster and help drive our commitment to inspiring a new generation of female athletes," said Amy Montagne, Nike's VP, GM of Global Categories. "We are thrilled to have her join our team."
Osaka is a two-time Grand Slam champion, and the first Japanese player to reach the No.1 spot.
The 21-year-old said she was "proud" to sign the deal, which begins this week; her first tournament in Nike gear will be the Porsche Tennis Grand Prix in Stuttgart, starting on April 22.
