The Springboks face a lose-lose scenario in Buenos Aires on Saturday, where defeat to Argentina could hand New Zealand top spot in the World Rugby rankings despite the All Blacks not playing a Test match this weekend.

South Africa enter the fixture on 93.96 rankings points, 1.68 ahead of New Zealand's 92.28. A loss by 15 points or fewer would see Rassie Erasmus' side drop to 91.96, narrowly behind the All Blacks. A heavier defeat — by more than 15 points — would leave the world champions on 90.96, almost two points adrift.

Victory, however, offers no rankings benefit. The 10.83-point differential between South Africa and seventh-ranked Argentina means a Springbok win yields zero movement on the table, a quirk of the rankings system that penalises dominant sides facing lower-ranked opposition.

Fourth loss on Argentinian soil?

A defeat would mark South Africa's fourth loss on Argentinian soil, a record that underscores Los Pumas' growing threat at home. Argentina, meanwhile, have everything to play for: victory would lift them above Scotland into sixth, while a win by more than 15 points would also leapfrog England into fifth.

The stakes are sharpened by the looming series against New Zealand, where the Springboks will need to reclaim any lost ground. Saturday's fixture, then, is less about reward than risk — a Test where the world champions must navigate a hostile Vélez Sarsfield without the safety net of rankings insurance.

For Erasmus, the task is clear: avoid the banana skin and preserve top spot ahead of the Greatest Rivalry Tests. Anything less hands the All Blacks a rankings advantage without them lifting a finger.
