Wales Under-20s claimed their highest finish at the IRB Junior World Championship by beating Argentina in Friday's third place play-off.
The Newlands win was built on a fine Welsh pack, which caused problems for the usually unruffled Argentina eight.
Wales led 19-0 at half-time as wing Tom Prydie kicked four penalties and converted a penalty try.
Facundo Isa and Juan Cappiello tries threatened an Argentina comeback but two more Prydie kicks saw Wales home.
Argentina suffered from indiscipline in the first half, coughing up a string of penalties and having two players sin-binned.
First flanker Joaquin Camacho was yellow-carded on 21 minutes for kicking a ball coming out of a Welsh ruck when he was lying on the ground, with lock Juan Cruz Guillemaín following him to the sidelines six minutes later.
Wales also had replacement Gareth Thomas sin-binned late in the game for a dangerous tackle, but the 14 men held out in the closing moments to claim a deserved third place.
Danny Wilson's junior Welsh side recorded a shock 9-6 victory over defending champions New Zealand in the pool stages, also defeating Fiji and Samoa, but were beaten by a rejuvenated Baby Blacks 30-6 in the semi-finals.
