Wales halted a run of five straight rugby losses by holding out for a 24-20 win over Argentina on Saturday, marking an impressive comeback from its chastening defeat to Australia last weekend.
Winger Liam Williams and scrumhalf Gareth Davies scored tries early in the second half for the Welsh, who then kept the Pumas at bay thanks to two penalties from fullback Leigh Halfpenny.
Wales led 6-3 at halftime and kept it tight in the final 20 minutes to close out the game, showing a massive improvement defensively from the 32-8 rout by the Wallabies - its heaviest loss in more than a decade.
"We turned into the great entertainers today," Wales lock Alun-Wyn Jones said, sarcastically.
Argentina arrived in Cardiff having racked up a half-century of points in a win against Japan but was strangely subdued, scoring tries through Juan Martin Hernandez and scrumhalf Martin Landajo with rare forays into the Welsh 22. The Pumas have lost five of their last six matches against Wales.
