Wales cruised past 2007 World Cup semi-finalists Argentina with a 28-13 victory at the Millennium Stadium in their final warm-up Test ahead of September's World Cup.

Argentina dominated the opening exchanges but they were hit by a sucker punch by Wales who grabbed two quick-fire tries through Andy Powell and Alun Wyn Jones with James Hook converting both.

Hook stretched Wales' lead with a succession of second-half penalties before George North crashed over for yet another try.

Argentina grabbed a late consolation through Martin Scelzo which Felipe Contepomi converted but the result was already beyond doubt.

Wales were determined to build on the triumph over England last weekend and enter their World Cup opener against world champions South Africa on September, 11, on the back of two victories.

Wales coach Warren Gatland was pleased with the manner in which a team that showed nine changes from last Saturday's win over England had coped with a tough Pumas outfit.

"We took a bit of time to settle, but we then took our opportunities very well," said the New Zealander, who will name his squad on Monday.

"The second try especially was very clinical, and it is about taking those opportunities when they are there.

"We believe we are in good shape physically, and we have won five of our last seven games. We have that confidence."

One worry, though, for Wales was they lost veteran fly-half Stephen Jones before kick-off, with a recurrence of his calf injury, with Scott Williams stepping up to the bench but Gatland was optimistic that he would be fit.

"Stephen Jones had a scan last night," said Gatland.

"He felt the calf a little bit in training, but it is not a huge concern for us."

Argentina veteran Contepomi said that it wasn't a bad performance by his side given it was their first Test of the year - but they have just one more match before they take on England in their World Cup opener against England on September 10.

"That was our first Test for a long time, but I believe we made a step forward," said Contepomi.

"In terms of the game plan and structure, we did well, but individual errors in terms of decision-making cost us.

"I think we are moving in the right direction, we just need to solve these errors."
