Wales head coach Wayne Pivac has made three changes to the starting XV that beat Canada last week as Argentina arrive in Cardiff for the first of two test matches.
The forward pack remains unchanged with man-of-the-match from last week Ben Carter retaining his place in the second row alongside Cardiff duo Dillon Lewis at tighthead prop and James Botham at openside flanker.
There are three changes in the backs as Kieran Hardy replaces Tomos Williams at scrum-half, while Cardiff duo Owen Lane and Hallam Amos named in the back three with Lane replacing Tom Rogers on the wing and Amos in for the injured Leigh Halfpenny at full-back.
On the bench the forward options remain unchanged, with Josh Turnbull again covering second row, while Jarrod Evans is fit to cover half-back alongside Williams having missed out against Canada due to an ankle injury.
Wales: Hallam Amos, Jonah Holmes, Uilisi Halaholo, Jon Davies (c), Owen Lane, Callum Sheedy, Kieran Hardy; Nicky Smith, Elliot Dee, Dillon Lewis, Ben Carter, Will Rowlands, Ross Moriarty, James Botham, Aaron Wainwright
Replacements: Ryan Elias, Gareth Thomas, Leon Brown, Josh Turnbull, Taine Basham, Tomos Williams, Jarrod Evans, Nick Tompkins
