Tries from No 8 Taulupe Faletau and scrum-half Tomos Williams took Wales to a 20-13 victory over a below-par Argentina in their autumn international fixture at the Principality Stadium.
Wales fell 6-0 behind early on but from that moment looked the likely winners as they showed considerably more control in possession and defensive solidity than in the 55-23 hammering they endured against New Zealand last weekend.
