The Blitzboks made a successful start to the Singapore Sevens on Saturday by winning their first two games.
They first knocked over Samoa 26-5, and then held off a spirited Canada 21-12.
In the second match, the South Africans held a 14-7 halftime lead after trailing 7-0 initially through an Andrew Coe try.
But a good step and swerve by Siviwe Soyizwapi got his team on the board to level the scores, before Cecil Afrika dotted down to secure the lead.
Canada didn’t stop going, though, and Tevaughn Campbell hit back to bring Canada within two points at 14-12.
But new Blitzbok sensation Selvyn Davids provided the spark in the latter stages, using his electric pace to grab a brace and clinch victory for Neil Powell’s team.
In the first game against Samoa, the South Africans also scored four tries, through Werner Kok, Soyizwapi, Rosko Specman and Muller du Plessis.
The Blitzboks’ final match of day one is at 1pm SA time against Argentina.
