Wilkins, the Ohio-based boarder who became the youngest vert X Games winner when earning a surprise gold last year, securing $35,000 (£22,000/€31,000) in prize money.

He won ahead of Washington's Mitchie Brusco, while California's Pierre Luc Gagnon placed third. 

Despite the US domination, there was some international presence further down the leaderboard, with Britain's Paul Luc Rochetti fourth and Brazil's Marcelo Bastos sixth.

Qualifying also took place for tomorrow's much-anticipated Street World Championship final, with this event one of those proposed for Olympic inclusion at Tokyo 2020.

Another Brazilian in Luan Oliveira led the way, ahead of a trio of Americans in Nyjah Huston, Yoshi Tanenbaum and Chase Webb.

The Championships are being sanctioned by the World Skateboarding Federation, one of at least three governing bodies which represents the sport along with the rival International Skateboarding Federation and the International Roller Skating Federation.

The WSF, led by Tim McFerran, has provided financial assistance to over 50 skaters to help them pay for travel expenses to South Africa.

Street and Park skateboarding was shortlisted for Olympic inclusion last month along with baseball and softball, karate, sport climbing and surfing, with a final decision set to be made at next year's International Olympic Committee (IOC) Session in Rio de Janeiro.
