Ronwen Williams made four saves as South Africa beat Cape Verde 2-1 on penalties to reach the Africa Cup of Nations semi-finals on Saturday.

The Bafana Bafana goalkeeper also made a stunning stop at the end of normal time as the last-eight clash in Yamoussoukro ended goalless.

It was his fourth successive clean sheet in the tournament.

Cape Verde created the most chances throughout the game but were unable to make the most of their opportunities and South Africa, the 1996 champions, will now play Nigeria for a place in the final.

The first half was a cagey affair with neither goalkeeper seriously tested.

Kevin Pina had an opportunity for Cape Verde but headed well wide at the back post before South Africa’s Teboho Mokoena lashed a long-range shot straight at Vozinha.

A chance opened up for Themba Zwane after South Africa snatched possession and broke forward but he scuffed his shot wide.

Pina again missed the target at the other end after skipping around two challenges and Ryan Mendes also had an effort blocked after weaving through the area.

Cape Verde had the first chance of the second half when Joao Paulo volleyed wide but South Africa had an opportunity when Khuliso Mudau shot at Vozinha.

Garry Rodrigues could have given Cape Verde the lead when he got behind the defence just before the hour but he failed to get any power on his attempt to curl a shot around Williams.

Cape Verde stepped up the pressure and Rodrigues had an effort deflected for a corner and a Rocha shot was blocked before Jovane Cobral fired over.

Gilson Benchimol almost won it for Cape Verde in the second minute of stoppage time after racing onto a Logan Costa ball but Williams did brilliantly to palm his powerful effort onto the bar.

Extra time began with South Africa in the ascendancy but Vozinha came to Cape Verde’s rescue with two superb saves in quick succession from substitute Mihlali Mayambela and Mokoena.

Benchimol spurned another chance but neither side looked threatening in the second additional period and penalties became inevitable.

South Africa seized the early initiative in the shoot-out as Williams saved the first two spot-kicks from former Manchester United forward Bebe and Willy Semedo.

Zakhele Lepasa’s failure to hit the target gave Cape Verde hope but Williams then kept out Laros Duarte’s effort.

Vozinha saved from Aubrey Modiba in response and Bryan Teixeira finally registered for Cape Verde but Mothobi Mvala put South Africa on the brink and Williams completed the job by saving from Patrick Andrade.

Nigeria edged past Angola 1-0 to reach the Africa Cup of Nations semi-finals thanks to a first-half goal from Ademola Lookman.

The former Fulham and Everton winger crashed home the only goal of the game in the 41st minute as the Super Eagles, chasing a fourth AFCON title, came up against a determined resistance in Abidjan.

Jose Peseiro’s side will face the winner of Cape Verde against South Africa, who meet in Yamoussoukro on Saturday, for a place in the final.

Nigeria’s star striker Victor Osimhen twice went close in the first half with headers, the first when he got on the end of Moses Simon’s cross but could only guide this effort into the goalkeeper’s hands, then again when he nodded across goal after meeting Ola Aina’s long throw.

What would prove to be the winning goal arrived four minutes before half-time and Simon was the architect.

Alex Iwobi began the move with a sweeping ball from right to left. Nantes winger Simon found space with a well-time run down the wing and, having carried the ball to the byline, looked up and found Lookman. He evaded the attentions of Angola’s defence and hit a thumping first-time finish into the roof of the net.

Early in the second half, Calvin Bassey took the ball off the foot of team-mate Osimhen as he sought to execute a close-range overhead kick, the Fulham player nodding over the bar after Angola failed to clear a corner, as Nigeria sought to settle the game.

Minutes later, Angola came within an inch of levelling. Zini sprung Nigeria’s offside trip with an expertly timed run from a defence-splitting pass. Bearing down one-on-one against Stanley Nwabali, he opened up his right foot and despatched an effort that rebounded off the inside of the post and away to safety.

Osimhen thought he had made it 2-0 when his header from Bassey’s free-kick went in off the post, but the goal was ruled out by VAR for offside, to the relief of Angola goalkeeper Antonio Dominique who had allowed the ball to squeeze through his hands.

The Napoli striker spurned another chance to seal it with 10 minutes to play, racing on to Lookman’s ball out from the back and running through on goal. He was denied by a superb last-ditch block from defender Kialonda Gaspar who deflected the ball away.

Franck Kessie scored the winning penalty as hosts Ivory Coast sent holders Senegal tumbling out of the Africa Cup of Nations, sparking wild celebrations in Yamoussoukro.

Kessie, who had coolly dispatched an 86th-minute spot-kick past Edouard Mendy to earn a 1-1 draw send the round-of-16 tie to extra time, delivered again with the crucial kick to seal a 5-4 shoot-out win after Moussa Niakhate had missed for favourites Senegal.

The Ivory Coast’s win continued a remarkable revival for the hosts, who had looked down and out in the group stage after a 4-0 humiliation at the hands of Equatorial Guinea.

Senegal had looked set to end the curse that had seen no defending champions reach the last eight since 2010 when Habib Diallo rifled home with just four minutes on the clock.

The hosts responded well as they pinned Senegal back in their own half, but the holders’ defence held firm and Ivory Coast were restricted to a succession of half-chances.

Seko Fofana’s run into a dangerous area was superbly snuffed out by Niakhate and Senegal almost extended their advantage on the stroke of half-time when Ismaila Sarr stumbled over a shooting chance.

Sarr came close again early in the second half but Ivory Coast continued to press through Oumar Diakite, who almost served up a leveller for Jean Philippe Krasso just before the hour mark.

The holders missed an even better opportunity in the 74th minute when Kessie’s free-kick was parried by Mendy, who somehow got in the way of the same player’s follow-up from a tight angle.

Substitute Nicolas Pepe missed another huge chance when he lashed a curling effort straight at Mendy, but earned his side their crucial penalty four minutes from time when he was tripped by Mendy in the box.

Kessie kept his cool to force the additional half-hour and after neither side could break the deadlock, it came down to the shoot-out where the hosts scored all five to seal a famous triumph.

Franck Kessie stepped up from the penalty spot to send defending champions Senegal tumbling out of the Africa Cup of Nations and spark wild celebrations in Yamoussoukro.

Kessie had given hosts Ivory Coast hope when he coolly dispatched an 86th-minute spot-kick past Senegal goalkeeper Edouard Mendy to send the tie into extra-time.

And the 27-year-old delivered once again with the crucial kick to seal a 5-4 win in the shoot-out after Moussa Niakhate had missed his earlier effort for the favourites.
