Argentina unleashed some of their best attacking rugby to beat Romania 43-8 in the World Cup match in Invercargill on Saturday.
The Pumas scored six tries to one as they rebounded from their 9-13 loss to England last weekend in front of a boisterous crowd of 12, 605.
They had the game under control at halftime and added two tries in the second spell against a Romanian side which tried hard but which was outgunned except in the set scrums.
Flanker Juan Leguizamon was everywhere for Argentina, Rodrigo Roncero had a strong game in the front row and the backs - especially fullback Lucas Amorosino, centre Marcelo Bosch and Martin Rodriguez - shone.
Argentina had won their seven previous Tests against Romania and started as the overwhelming favourite.
Both had been narrow losers in the opening round, Argentina going down 9-13 to England and Romania conceding two late tries to lose 24-34 to Scotland.
The Pumas made a strong start, hooker Mario Ledesma making ground up the middle and creating quick phase ball from which fly-half Santiago Fernandez cut through for a try by the posts after five minutes.
Four minutes later good inter-passing among the forwards allowed openside flanker Juan Leguizaman to burst the last 25 metres to score.
Rodriguez converted both tries and Argentina led 14-0 after nine minutes.
The Romanian defence was under siege and there was a third try after 21 minutes when prop Juan Figallo crashed over from a forward drive to make it 19-3.
The Pumas were rampant and scored their fourth (bonus point) try after 30 minutes from a sweeping move involving backs and forwards before fullback Lucas Amorosino sidestepped the last defender to score under the posts.
But Romania broke back two minutes later with a fine try by left wing Ionel Cazan and it was 26-8 in a point-a-minute entertainer.
Argentina was fully deserving of their 18-point halftime lead. It was prepared to run the ball from most parts of the ground, its support play was impressive and it could have added two or three more tries had last passes gone to hand.
Argentina had 60 percent of possession, made three clean line breaks to none and forced Romania to make 75 tackles, of which 13 were missed.
The Pumas went straight on to the attack in after the interval and a penalty from 30m and in front by Rodriguez extended their lead to 29-8.
Romanian prop Mihaita Lazar was sin-binned for collapsing a maul 13 minutes into the half but his team-mates defended resolutely until replacement wing Juan Imhoff spotted a gap and raced under the posts for the fifth try. Rodriguez converted and it was 36-8.
Argentina loosened up a little in the second spell as it made substitutions while the Romanians tightened up after they were doubtless on the end of a halftime team talk.
Eight minutes from the end Argentina turned defence into attack and replacement flanker Julio Farias Cabello raced 40m for the sixth try. Rodriguez converted and it was 43-8.
