Dale Steyn made his comeback following a month out with a rib injury and took three wickets in a practice match against a Rest of South Africa side.
Bowling at 'moderate' speeds he took three for 40 as South Africa dismissed their opponents for 135.
The game, at the Wanderers Stadium in Johannesburg, is part of the Proteas' preparations for next week's opening Test against Australia.
Bowling coach Allan Donald said he was pleased with how the day went, and a welcome return to action for Steyn.
"I'm very happy with the whole group," he said. "It was a good workout, nice time on the legs. When you prepare for a Test series, time on the legs and some mileage in terms of balls bowled is absolutely crucial.
"Hopefully the weather holds up for us tomorrow so that we can finish with a spell or two, especially Vernon (Philander), Morne (Morkel) and Dale (Steyn)."
The South Africans, who scored 300 in their first innings, closed the day on 147 for five. JP Duminy retired hurt with a sore wrist and will be assessed today.
Steyn was diagnosed with a small rib fracture following the second Test against India in Durban late last year.
