South Africa demolished Afghanistan's T20 World Cup dream in ruthless fashion, thrashing the minnows by nine wickets with more than 11 overs to spare to reach the final of the cricket showpiece for the first time.

Rassie van der Dussen hit an unbeaten 76 to lead South Africa to a comfortable five-wicket win over Afghanistan in their last World Cup group game on Friday as their opponents were eliminated from the semi-final race.
