South Africa qualified for the Rugby World Cup quarter-finals thanks to a 64-0 demolition of the USA in London on Wednesday.
Veteran wing Bryan Habana was the star of the show as he scored three tries to draw level with Jonah Lomu's all-time RWC try-scoring record of 15.
The results sees the Springboks secure top spot in Pool B and sets up a clash with the losers of Saturday's showdown between Australia and Wales at Twickenham. Meanwhile the USA will now look to their match with Japan on Sunday as they search for their first win of the tournament.
Off the platform of a totally dominant scrum, the Springboks scored ten unanswered tries, yet coach Heyneke Meyer will have mixed feelings about the performance of his strongest available side.
South Africa's total physical dominance was juxtaposed by their poor execution on attack in the first half.
Indeed, the Boks would have been disappointed by their first 40 minutes as a glut of unforced handling errors and below-par kicks left much to be desired. There was a distinct lack of composure shown as the Boks threw loose passes and made overly-hasty decisions.
South Africa led 14-0 at the interval thanks to a try from Damian de Allende and a penalty try awarded against the American scrum.
The second-half was a different story however as the Eagles crumbled.
Habana sealed his hat-trick in the space of 20 minutes and Bismarck du Plessis, Francois Louw — who scored twice — Jesse Kriel and Lwazi Mvovo all followed him onto the scoresheet.
The Eagles had the first chance at points but Folau Niua's long-range penalty fell short.
The early signs were ominous for the Americans though as the Springbok pack rumbled forward at the first scrum.
The Boks were sloppy in the early minutes but the opening try wasn't long in coming. Schalk Burger slapped a loose ball along the ground and De Allende took advantage of the unstructured situation, splitting the US defence open before handing off Danny Barrett to score.
Handre Pollard added the extras, meaning the Boks led by seven after as many minutes.
It was the Eagles however who dominated possession in the first quarter but Niku Kruger couldn't find the target from the kicking tee either, leaving the USA empty handed despite a promising opening 20 minutes.
An almighty clash in mid-air between Habana and Blaine Scully saw both men sent for concussion assessments. In Habana's brief absence Kriel shifted to the wing and was stopped just short of the line after a break by Pollard.
A series of scrums ensued and the Boks were rewarded for their superiority at the set-piece with a penalty try. Curiously though, referee Pascal Gauzere only raised his arm under the posts after Pollard had overcooked a crossfield kick.
Pollard added the inevitable conversion to take the lead to 14 points and the men in green should have had another try but Duane Vermeulen butchered a sure thing by knocking on with line in sight.
Fourie du Preez was the architect of a gem of a try almost immediately after the second-half restart, placing a glorious chip into space for Habana to run onto and finish untouched. Pollard's conversion made it 21-0.
Du Plessis muscled his way over soon after from close range after Vermeulen was stopped short from a charge off the back of an attacking scrum.
The floodgates had opened and Louw got his first try at the back of an unstoppable rolling maul. Pollard made it 33-0.
Habana scored his second thanks to an offload from De Allende with Morne Styen landing his first points of the tournament with the conversion.
The Eagles were out on their feet and another maul set up Habana's third try, an easy run in. Steyn again hit the target.
Yet another maul took Louw over for his brace before Kriel used his pace to race home.
Habana fumbled in the act of going over for what would have been a record-breaking try but the Boks still had the last laugh as Mvovo pounced on a loose ball and raced home from his own 22. Steyn took the score to 64 after the final hooter.
Man of the match: Mentions must go to young locks Lood de Jager and Eben Etzebeth, who were at the heart of South Africa's physical dominance. But you can't ignore the guy who scored a hat-trick, Bryan Habana.
Moment of the match: The spark that started the fire was Fourie du Preez's great chip into space to create Habana's first try.
Villain of the match: No nasty stuff to report.

John McKee's men were determined to end the tournament on a positive note after coming in with such high hopes, and did so by scoring seven tries, including two penalty tries stemming from their dominant scrum.
Having trailed 15-0 early in the second half, Romania launched an impressive comeback, with the power of their forwards turning the tables on a Canadian side that had controlled the game for the first 50 minutes.
The result means that Ireland and France will qualify from Pool D, with their showndown next weekend set to decide who tops the group.
In this kind of form they will be a match for anyone in the latter stages of the competition and it's worth noting this performance was put on without the quality of centres Juan Martin Hernandez and Marcelo Bosch. Nicolas Sánchez was superb.
The Wallabies' sharper cutting edge in attack was on full display in both of their first-half tries, both finished by Bernard Foley who scored nearly all of their points in a classy performance from Michael Cheika's ever-improving side.
The Springboks outscored Scotland three tries to one in front of almost 51,000 fans at St. James' Park, moving to the top of Pool B in the process. The result also means that victory over the USA on Wednesday will secure Heyneke Mayer's team a place in the pay-off stages.
The Brave Blossoms thoroughly deserved their four points as they dominated their pool rivals for large spells in an impressively calm showing.
Julian Savea scored a hat-trick but it was far from the perfect performance, and Richie McCaw worryingly limped off after an hour, as New Zealand took their foot off the gas after picking up the bonus point inside 21 minutes.
28,145 fans were packed into the venue for a record crowd and they were treated to another entertaining 80 minutes as the underdog once again stood up tall.
Gareth Davies had Wales on the board after only six minutes with Scott Baldwin scoring their second in an open, entertaining first half that Wales dominated to lead 17-6.
Coming in at the last minute, Veainu got Tonga off the mark after just five minutes, with Ram following that up inside the first 15 minutes.
It took the Six Nations champions over 60 minutes to notch up their bonus point try before they ran riot late on, watched by 89,267 fans of which well over half were present wearing green.
It was a match of two halves as Vern Cotter's charges, who were well off the pace in the opening 40 minutes, found their form as they moved top of Pool B.
Gareth Davies' spectacular try for Wales with ten minutes to go flipped the contest on its head after they had trailed for over 40 minutes.
After Wales' comeback win over England, Australia continued to ease into the competition, scoring 11 tries against the pool's weakest side.
