A goal in either half courtesy of Mwati Mavuso and Tyreese Pillay respectively was enough to get the job done for an Amajimbos side that topped Group A.
Just before the break South Africa got their opener through Mswati who went from hero to villain when he was later shown a red card.
Despite only having ten on the park Amajimbos battled away and were rewarded when they earned a penalty for a foul on S’miso Bophela.
Pillay stepped up and scored from the spot to hand his side a comfortable victory and safe passage through to a semi-final showdown with Malawi on Friday.
South Africa's indomitable youngsters are yet to concede a goal in the competition so far and scored seven in their three group games.
