Cape Town - South Africa made a solid start to their title defence of the Las Vegas Sevens in he early hours of Saturday morning, racking up solid wins over Portugal and Japan to lead their pool.
Once again it was speedster Seabelo Senatla that stood out, scoring three tries in the two games as the Blitzboks looked focused and determined by their task.
The defending champs began the tournament with a workmanlike 19-0 win over a plucky Portugese side, who were more than a handful on the day.
