South Africa defeated Argentina to secure consecutive Rugby Championship titles for the initial occasion.
The title holders entered the contest knowing that any win would earn them the championship due to their superior points difference.
Argentina opened powerfully with an early try from Bautista Delguy and secured a 13-10 lead at midway point.
However, the Springboks took charge after the interval, following up Cobus Reinach's first-half try with a score from Malcolm Marx.
Further tries from both Reinach and Marx extended the lead before Delguy snatched the ball and raced clear for his double try of the match.
The encounter was played before a audience of 70,360 spectators, with Argentina organizing the match at a expanded venue to increase attendance totals.
Replacement wing Rodrigo Isgro touched down after gathering a cross-field kick in the final play to obtain a consolation point.
Despite achieving impressive victories over other teams, Argentina finished at the foot of the Rugby Championship standings.
The winners recovered from early losses in their opening three championship matches to secure three straight victories, including a significant defeat of competing team.
Winning the trophy before a large crowd, which included plenty of fans from the South African population, provided a suitable conclusion to their journey.
The visitors had previously demonstrated their capability against the same rivals the prior weekend, with fly-half Sacha Feinberg-Mngomezulu establishing a team record for points scored.
While several strategies and moves had worked in the earlier encounter, the initial period in London demonstrated more challenging.
An initial yellow card for a head-on-head tackle resulted in Argentina capitalizing through effective attacking play concluded by Delguy.
The Argentinian team managed to take advantage of the visitors's rush defense through rapid passing and added two points either side of Feinberg-Mngomezulu's accurate kick.
Despite having trouble to establish their pattern, South Africa's dominant scrum was finally rewarded when Reinach touched down for a vital try right before midway.
Early in the after the break, an Argentina prop was penalized for a high tackle, and Marx strongly finished from the following driving maul.
While chances arose for skilful backline players to display their footwork, windy conditions benefited South Africa's power game through their pack.
Reinach's additional try came after a impressive carry from a bench player, who cleverly offloaded with one arm, while Marx then pushed over as the defense struggled stopping the attack near the tryline.
Before the previous triumph, South Africa had only won the competition four times in their history.
Throughout the competition, the coaching staff alternated the squad and cultivated young talent, including promising players in various positions.
Now the successive world champions are creating an formidable squad for future competitions, accustomed to winning tournaments.
