The world’s fastest teenager is suing one of the biggest brands in sports.

Issam Asinga, still just 19, took the track and field world by storm in 2023. He ran 9.89 for 100 meters and beat Noah Lyles, who went on to win the World Championships in the 100 meters last year and is among the major favorites to win Olympic gold in Paris later this summer. Asinga’s 9.89 was a new world junior record and made him the first U.S. high schooler to break 10 seconds. (He represents Suriname internationally.)
