Third-string scrumhalf Cobus Reinach scored a hat-trick of tries in 11 minutes as South Africa celebrated their 500th Test by storming into the Rugby World Cup quarterfinals with a 66-7 victory over Canada on Tuesday.
The Springboks ran in six tries in the first half-hour at Kobe Misaki Stadium, and Canada's woes deepened a couple of minutes when replacement lock Josh Larsen was shown a red card for an illegal shoulder charge at a ruck just moments before the interval.
South Africa were unable to maintain the pace in the second half, and the short-handed Canadians scored a deserved try through flanker Matt Heaton in the 46th minute.
The Springboks still had very much the better of the contest, though, and four tries after the departure of Larsen sent them through to the knockout stages with a spring in their step.
Centres Damian de Allende and Frans Steyn, wings Sbu Nkosi and Warrick Gelant, hooker Schalk Brits, full-back Damian Willemse and prop Frans Malherbe also crossed the tryline for South Africa.
"It feels really good, especially after that performance," Springboks skipper Siya Kolisi said.
"I'm really proud of the boys, especially in the first half. In the second half we got a bit looser, but the main thing is the boys had a lot of fun."
The Boks' dominance in the opening 40 minutes was stark as they cut the Canadian defence apart with speed at the ruck, slick hands and an intelligent kicking game.cIt was at times gruesome viewing for Canada's supporters as their team struggled to get their hands on the ball and had to withstand wave after wave of powerful raids on their line.
The Boks had wrapped up the bonus-point they needed to secure a quarterfinal berth by the 18th minute, with the best of those tries coming from Reinach as he picked up the ball at the base of a ruck inside his own 22 and scythed through a gap in the defence. Faced with a lone defender, Reinach chipped the ball ahead and collected his own kick for one of the great individual scores of the tournament so far.
Canada were at times their own worst enemy, and they went a man down when Larsen showed too much enthusiasm at a ruck on 36 minutes; his right shoulder connected with the neck of Springboks prop Thomas du Toit.
Canada, to their credit, looked much more assured in the second half despite their numerical disadvantage, and Heaton scored his first international try after they had won a succession of penalties. It should have been his second but he had dropped the ball over the tryline in Canada's defeat by Italy earlier in the competition.
The Boks were kept scoreless for 15 minutes in the second half before Brits showed strength and quick feet to barge over the line.
Willemse, parachuted into the squad as an injury replacement for Jesse Kriel, later scored his maiden test try.
"Very tough, we couldn't even get our hands on the ball for that first 30 minutes or so, and when they had it they did some damage," Canada captain Tyler Ardron said.
"But I felt we grew into the game, and in that last 50 we put in a better performance.
"It's never helpful to get a red card. I think we would have rather had the 15 out, there but we pulled together."
