Los Pumas, Perth defending champions, held on to deny the Blitzboks in their final pool match of the Perth Sevens on Saturday, a result that consigned South Africa to a quarter-final against Fiji.
The Blitzboks knocked on from the opening kick-off and the errors mounted in the first half as Argentina asserted physical dominance in the collisions to keep them pinned back in defence, racing to a 19-0 first-half lead with tries from Matteo Graziano, Marcos Moneta and Matias Osadsczuk.
But South Africa responded after the restart, the tide turning when Argentina made a mess of a lineout and the Blitzboks stole the ball to send Quewin Nortje down the left touchline for a turnover try.
Another turnover, another Blitzboks try as Selvyn Davids dotted a perfectly-weighted Ronald Brown grubber to make it 19-10 with four minutes to go.
Shilton van Wyk cut the deficit to two points as the Blitzboks converted an attacking lineout into a try, but Argentina successfully received the ensuing restart and hoofed the ball into touch to draw the final whistle.
On the back of the win, Argentina finished top of Pool A to book a Cup quarter-final showdown against Great Britain, while the Blitzboks will take on Pool C winners Fiji (kick-off 12.19pm).
