The Blitzboks followed up their 17-0 whitewash at the hands of Ireland in their opening game of the Los Angeles Sevens by slipping to another defeat, this time 17-5 to Argentina, that effectively puts them out of the race for the Cup.
It looked good for the South Africans when Rosko Specman scored a try after three minutes but Joaquin Pellandini scored a try for the Los Pumas to level the score at 5-all on the stroke of halftime.
Four minutes into the second half it was Luciano Gonzales who crossed to give his team the lead for the first time and then a minute later he made the game safe for his team with another five pointer to make it 17-5 to Argentina after another disappointing showing from the South Africans.
The final Blitzbok game of the day will be against Spain after midnight South African time but the Blitzboks are playing only for minor finishing positions from here.
