Springboks secure last-eight spot
Defending champions South Africa advanced to the World Cup quarter-finals by winning Pool D with a 100% record after beating Samoa 13-5 in a titanic tussle at North Harbour Stadium in Albany.
All of South Africa's points came in the first half, but despite a mighty effort, Samoa, who were reduced to 14 men when Paul Williams was sent off late on, were unable to keep their last-eight hopes alive.
Bryan Habana scored a ninth-minute try, Morne Steyn added the conversion and a penalty and Frans Steyn kicked a penalty from his own half for the Springboks, who are set to play the runners-up in Pool C in Wellington next Sunday.
George Stowers' second-half try was not enough for Samoa, who had full-back Williams sent off after 70 minutes for punching Heinrich Brussow.
South Africa also finished the match with 14 men after captain John Smit, on as a replacement, was shown a yellow card for kicking the ball away.
Samoa's failure to get a losing bonus point means they are set to finish third in the pool and Wales should advance as runners-up, barring a major shock against Fiji on Sunday.
