 South Sedana ranked 33rd in the world but led at half-time. They even went ahead again with 20 seconds to go when JT Thor, who plays for the Charlotte Hornets, scored a three-pointer at London's O2 Arena. But with eight seconds remaining, LeBron James showed why he's the NBA's highest-ever points scorer, making a driving layup to secure a 101-100 victory and spare the US the humiliation of a shock defeat.
