Flyhalf Tomas Albornoz kicked a penalty 11 minutes from the end to hand Argentina a thrilling 29-28 victory over South Africa and keep its hopes of winning the Rugby Championship alive in a blisteringly hot Santiago del Estero on Saturday.

The world champion Springboks, who had the chance to win the game with a late penalty from flyhalf Manie Libbok that was missed, lead the table with 19 points from second-placed Argentina on 14 points ahead of a final meeting between the sides in South Africa next Saturday, where the title will be decided.

Argentina scored four tries through wing Mateo Carreras, flanker Pablo Matera, prop Joel Sclavi and Albornoz as the team took advantage of a first-half yellow card for visiting wing Kurt-Lee Arendse and turned a 17-0 deficit into a 26-22 halftime lead.
