The Blitzboks got their Tokyo Olympic campaign off to a flying start as they beat Ireland in their opening Pool C encounter at Tokyo Stadium on Monday.
South Africa won 33-14 after leading 14-7 at half-time
The Blitzboks, who won bronze at the 2016 Rio Olympics, displayed a dominant performance against the Irish and put to bed any rustiness or concerns after Covid-19 hit the camp.
Renfred Dazel is taking charge of the side with head coach Neil Powell still in isolation in Kagoshima after testing positive for the virus.
South Africa scored five tries through Zain Davids, Impi Visser, Justin Geduld, Chris Dry and Stedman Gans, while Selwyn Davids slotted four conversions.
Meanwhile, the Irish replied with two tries by Gavin Mullin and Terry Kennedy, with Billy Dardis landing both conversions.
The Blitzboks' next Pool C match is scheduled for later in the day when they take on Kenya (12:00 SA time).
South Africa last played Kenya in the World Rugby Sevens Series in Los Angeles, winning 31-3.
Overall, the Blitzboks have won 52 of their clashes against the Kenyans in the world series, losing six, with one match drawn.
