Coach Chris Davey has made three changes to the starting line-up of the Wales under-21 side that defeated Italy in the opening game of the IRB's under-21 World Cup, when they take on Argentina today at the Rand Afrikaans University ground.
Italy were beaten by 82-18 with 12 tries being run in by a rampant Wales side last Friday, but now they will face a much tougher test.
Matthew Nuthall replaces Nick Jones on the wing, Adam Matthews for Matt Miles as hooker and Robin Sowden-Taylor for Gareth Williams on the flank.
With Dwayne Peel having returned home after being injured at Cape Town on Saturday, Cardiff's Craig Miller will be the scrum half replacement.
The side to meet Argentina is: G Swales; L Roberts, M Jones, M Brayley (capt), M Nuthall; N Robinson, M Phillips; P James, A Matthews, A Jones, Ryan Jones, L Tait, R Williams, Rhys Jones, R Sowden-Taylor. Replacements: C Miller, M Hook, S Williams, M Miles, G Morris, B Griffiths, G Williams.
