Flyhalf Manie Libbok was named man of the match as South Africa opened the defense of its Rugby World Cup title with a victory over Scotland on Sunday, as Wales held on against a spirited Fiji rally.

Libbok's highlight was a second-half, no-look assist for Kurt-Lee Arendse as the Springboks began their search for a record fourth Webb Ellis trophy in clinical fashion in the Marseille heat, winning 18-3.

Former World Player of the Year Pieter-Steph Du Toit crashed over earlier in the tie for Jacques Nienaber's outfit in Pool B.
