Argentina 67-14 Namibia
Argentina recovered from their disappointing display against Australia with a convincing win over a sprightly Namibian side.
The Pumas ran in a total of 10 tries but it failed to deter their effectively amateur opponents, who showed invention throughout.
Hakkies Husselman was the pick of the underdogs, continually launching fresh offensives, and was rewarded with a second-half try, one of only two by his side.
Du Preez Grobler had earlier scored on the stroke of half-time.
For Argentina, Martin Gaitan ran in the tournament's third hat-trick, Pablo Bouza scored a brace and there was one apiece for Federico Mendez and the Miranda brothers.
Referee Nigel Williams also awarded two penalty tries.
The best of the Pumas' four first-half tries came on the half-hour mark when Gonzalo Quesada unleashed a rare break.
The Pumas fly-half beautifully delayed his pass to Juan Fernandez Miranda, drawing in two defenders and allowing the centre to slide under the posts unopposed.
Earlier, Mendez had touched down after a short blind-side break, before Bouza scored from the base of the scrum.
A penalty try capped the Pumas' quartet of tries in the half but the biggest cheer was saved for the effort of Grobler in the final minute.
In Namibia's first really threatening attack, Grobler left the Argentine defence stranded with a brace of side-steps.
It took just five minutes after the re-start for the Pumas to get their scoring under way, Gaitan profiting from a string of sweet passes through the backs following a fluffed drop-out by Emile Wessels.
Gaitan produced a double within 10 minutes, landing the ball in practically the same spot with a monstrous overlap, only moments after his side had been awarded their second penalty try.
The centre completed his hat-trick in the dying minutes with another simple slide in.
Nicolas Fernandez Miranda matched his brother's earlier effort with a try of his own but, in a mirror of the first half, Namibia picked up a try again with their only realistic scoring opportunity of the half.
Deservedly it was Husselman who forced his way through amidst a melee of players on the Pumas' try line.
But Argentina were not yet finished, Bouza completing his brace again with a simple touch down 10 minutes from time before Gaitan completed his hat-trick
