The Blitzboks squad received a boost in their Olympic preparation on Friday when stalwarts Stedman Gans, Dylan Sage and Mfundo Ndhlovu all successfully returned to the team.
The Springboks Sevens played four matches against the SA All Stars Rugby Academy at Johannesburg Stadium.
The SA All Stars Rugby Academy provided much-needed opposition to the Blitzboks as the Blizboks opened their day with a 36-0 win with Kurt-Lee Arendse getting a brace.
The second match was another blow-out, with the national side winning 38-0, with six different players scoring.
In the third match of the day, two quick tries by Arendse in the first half and another late in the second set up a comfortable 53-7 win over the All Stars.
Muller du Plessis scored twice in the fourth match, with Ndhlovu also crossing in the 35-7 victory.
Gans has recently recovered from an ankle injury, while Sage needed time on the field after a year playing fifteens in France and Ndhlovu's newfound speed from his healed hamstring did not hold him back.
The three, all part of previous Blitzbok squads that have won the World Rugby Sevens Series, are not certainties for the Olympic squad, mainly due to their lack of sevens action in recent months.
Gans admitted some tension this morning.
"I was especially nervous before that first game, but all went well," he said.
"I am pleased to say that my ankle responded very well today and that's a great relief. I'm not lying when I say my lungs and legs are crying out, but that was expected. I know that match fitness is needed, that is why we're playing these matches.
"I realise that I can do better with special awareness as well, but all in good time. The important thing was to get through the day, and I did," said Gans.
Ndhlovu was also pleased with his effort: "I felt there were some areas where I needed to be sharper, but that improved during the day.
"It was a good outing; it's such a blessing to be back on the field. I am not aware of the injury, which showed the good work done by our medical team. I am forever grateful that they nursed me back to fitness. I really loved it out there today."
Sage thoroughly enjoyed his first run-out on a South African rugby field in more than a year.
"Great feeling, but it did not make it any easier. The fitness is still an issue, but I am happy that the feel for the game is still there," said Sage.
"We will do some reviews back at the hotel and have a look at areas to improve and then come back and try to execute tomorrow."
The team will have a live scrimmage session against the All-Stars Academy junior side on Saturday before a series of matches later in the afternoon.
The Blitzboks, who won bronze at the 2016 Rio Games, will be finalising their squad for next month's Tokyo Olympics, which gets underway from 23 July to 8 August.
