South Africa looked a very different team, in personnel as well as execution, in the slippery Pukekohe conditions.
Samoa are not a wet, cold weather side, but their line speed on defence and bruising running close to the rucks caused the Junior Boks some major headaches. They even managed to upset some of their vaunted lineouts and drives with their aggression as the "malosi" cries rang out around ECOLight Stadium.
South Africa seemed to invariably find the hard point of a Samoan shoulder, though Nathaniel Apa sailed too high in taking Sergeal Peterson around the head in the second half, for which he was sinbinned.
Captain Henry Stowers and fellow loose forwards So'otala Fa'aso'o and Richard Mariota led the charge. Samoa had already showed promising signs in pushing New Zealand hard, and beating Scotland 27-18 on Friday on the same ground.
There was not a penalty goal attempt until the 27th minute.
