CARDIFF, United Kingdom (AFP) — Faf du Plessis said South Africa must win all their remaining games if they are to have any chance of reaching the World Cup semi-finals after they notched their first win against Afghanistan yesterday.

The Proteas endured a torrid start to their campaign in England and Wales, 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 Afghanistan out for a meagre 125 before cantering to victory by nine wickets.

South Africa skipper Du Plessis said his players had upped their game in the match, which was reduced to 48 overs per side after two rain delays.

“Hopefully, this is a real confidence booster for everyone on the team,” he said. “And there’s a little bit of weight that you feel that’s off your shoulders now, so now the guys know what’s lying ahead.

“We need to win every game that we play. But today was a really good step in the right direction.”

South Africa, missing injured paceman Dale Steyn, lost to England, Bangladesh, and India before picking up a point in their rain-ruined match against the West Indies.

Their win yesterday lifts them to seventh in the 10-team table after five matches, but their chances of qualifying for the semi-finals by reaching the top four are remote, with New Zealand and Australia still to come in their remaining four games.

South Africa took their time in chasing down their target but Afghanistan, who look out of their depth at the World Cup, 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 in the 29th over.

There was little sign of the carnage to come when Hazratullah Zazai and Noor Ali Zadran put on 39 runs for Afghanistan’s first wicket.

Zazai was the first to go and when leg-spinner Tahir bowled Zadran for 32 with his first ball and then caught Asghar Afghan off his own bowling for nought in the same over, Afghanistan were in deep trouble.

Nabi became the third Afghan batsman to lose his wicket in the space of seven balls when he was bowled by Phehlukwayo.

When Naib was caught by Aiden Markram off the bowling of Tahir, Afghanistan were teetering on the brink of disaster at 77-7.

Rashid Khan struck 35 from 25 balls, with six fours, but even his late flourish could only lift the score to 125.
