South Africa kept alive their slim hopes of reaching the World Cup semi-finals, crushing Afghanistan by nine wickets on Saturday to record their first victory at the tournament.
Faf du Plessis's side endured a torrid start to their campaign, losing their first three matches before a no result against the West Indies.
But the outcome never looked in doubt in Cardiff, with man-of-the-match Imran Tahir taking four wickets as South Africa bundled out their opponents for a meagre 125 after two rain delays cut the match to 48 overs per side.
South Africa took their time in chasing their target but Afghanistan, who look out of their depth at the World Cup with four defeats in four matches, did not have the weapons to trouble their opponents.
Hashim Amla (41 not out) and Quinton de Kock (68), put on 104 for the first wicket before Afghanistan captain Gulbadin Naib had De Kock caught by Mohammad Nabi.
Amla and Andile Phehlukwayo saw South Africa over the line as they reached their revised target of 127 with 116 balls remaining.
"I really enjoyed that, really pleased," said Tahir. "It was important for me to take that role for the team. I have been working very hard and it's nice to have that first victory.
"We were up for it, we can't control the weather but the bowling group did well. My plan was to bowl my variations and get batsmen to make their mistakes. It came out well.
"As long as I take wickets I'll keep on celebrating."
