The Boks are in the No 2 spot in the latest IRB world rankings after their victory over Wales.
The Boks closed the gap on the first-placed All Blacks to 4.13 points thanks to their victory over Wales (20-15), while the Welsh dropped one spot to seventh.
France move up one place – to sixth – thanks to only their second victory over Argentina (12-6) in the last eight outings, and as a result the Pumas drop out of the top four.
Despite England’s 39-13 victory over the Pacific Islanders, deemed ineligible as the latter are a composite side, the English swap places with Argentina.
With the draw for the 2011 Rugby World Cup imminent, the Tests over the next three weekends will ensure extra incentive for teams to climb up the world rankings.
