Cape Town - The Blitzboks have defeated the United States by 14-12 to remain unbeaten in Pool A at the London Sevens, the final leg of the HSBC Sevens World Series.
South Africa only managed a single score in the first half through flyer Seabelo Senatla to lead 7-0 at half-time.
In the second half the Blitzboks extended their lead, running in an early converted try from Cecil Afrika.

They now meet Samoa in their final pool match at 17:48.
