The Nike Hoops Summit was a showcase for Ben Simmons and Dante Exum in recent years, but two of Australia's next wave of basketball talent did not fair so well.
The US, made up of America's best high school players, crushed the World squad on Saturday that included Australian 17-year-olds Harry Froling and William McDowell-White.
The US shot out to a 16-0 lead and were never challenged, ending with a 101-67 victory in Portland, Oregon.
Dallas guard Terrance Ferguson torched the international squad with 21 points, all on three-pointers.
Brazil's Wesley Silva was the top scorer for the World team with nine points.
