SA scored the opening goal in the 26th minute when Clint Panther produced a strong run along the left-hand baseline before giving himself room, but keeper Juan Vivaldi pulled off a fine save only for Nick Spooner to follow up on the rebound.
A lapse in concentration saw Juan Vilas steal in to equalise from Pedro Ibarra’s pinpoint cross for 1-1 in the 31st minute.
SA went ahead again in the 47th minute when Lungi Tsolekile took a free-hit in the attacking third of the field and passed infield to Geowynne Gamiet, whose immediate transfer saw Ignatuis Malgraff nail a superb goal.
Argentina equalised in the 52nd minute when the ball trickled in from a Lucas Martinez effort.
The result gave Argentina a 4-0 series win but SA’s steady improvement as the series wore on was a feature of the five matches.
