By taming the All Blacks 14-7 in an absorbing semifinal of the Cape Town Sevens on Sunday, the Blitzboks not only made sure of a showpiece match against England (kick-off at 19:44).
Far more importantly, they proved New Zealand rugby doesn’t have a stranglehold over South Africa when it comes to the sevens format.
This was, after all, a second consecutive victory over the old enemy after beating them 40-0 in Dubai last week.
The Blitzboks’ triumph may come at a price though.
Seabelo Senatla, South Africa’s try-machine, had come into the game carrying a calf niggle and despite setting up Branco du Preez’s try, he was replaced at half-time.
Another stalwart, Kyle Brown, had to be taken off the field with a golf cart after injuring his right knee try to compete at a breakdown.
Yet the Blitzboks’ bench has been the envy of many sides in this tournament and it showed its teeth once again.
With the game deadlocked at 7-all, replacement Rosco Speckman scored a spectacular, match-winning try after running 75m from a lineout.
His brilliant contribution made the All Blacks panic and thereafter they found themselves being frustrated by typically solid South African defending.
Point-scorers: Blitzboks (7) – Tries: Branco du Preez, Rosco Speckman. Conversions: Cecil Afrika, Du Preez. All Blacks (7) – Try: Sherwin Stowers. Conversion: Rocky Khan.
