Portugal Colonial - Ireland shock South Africa in Rugby World Cup Sevens

"Beating South Africa on their home patch –- it does not get much bigger than this," said Irish captain Billy Dardis.

Ireland silenced a big home crowd with a solid performance against the Blitzboks.

"We said we wanted to kill the party a bit," Dardis told SuperSport TV.

Ireland took advantage of early South African errors to score first through Mark Roche, but Muller du Plessis scored to put South Africa level at 7-7 at half-time.

Ireland took control after the break with tries by Harry McNulty and two by Jordan Conroy before Mfundo Ndhlovu scored a late try for the hosts.

Ireland will meet tournament favourites and title-holders New Zealand in the semi-finals on Sunday. New Zealand survived a tough quarter-final battle against Argentina, winning 12-5.

Rain made conditions tricky and Argentina were first to score through German Schulz.

But veteran forward Scott Curry scored a converted try for the All Blacks to give them a 7-5 half-time lead. A long-range solo try by Moses Leo in the second half settled the contest.

"As soon as the rain started coming down it got pretty slippery," Curry said.

New Zealand won the last two World Cups in 2013 and 2018 and came into Cape Town after winning the final event of the World Series in Los Angeles.

In the semi-finals, Australia will meet Fiji, who beat Samoa 21-10 with tries by Jerry Tuwai, Kaminieli Rasaku and Sevuloni Mocenacagi after Samoa had opened the scoring through Steve Onosai, who added a late consolation try.
