Proteas include Brevis for one-day games against Australia
Cricket South Africa on Monday named 18 players for a five-match one-day international series against Australia next month, the team's last outings before the Cricket World Cup in India.
But not all the players will be travelling to India for the tournament in October and November.
A 15-man World Cup squad will be named on September 5, two days before the first one-day international.
Some of the squad will be hoping to impress in three Twenty20 internationals before the one-day series.
They include Dewald Brevis, 20, who is set to make his international debut during the T20 series.
A hard-hitting batsman and leg-spin bowler, he will also be part of the one-day squad.
Brevis has only played in four first-class matches but has already been signed up by T20 franchises in India, South Africa, the West Indies and the United States. He made 162 off 57 balls in a domestic T20 match for the Titans against the Knights last October.
Batsmen Matthew Breetzke, 24, and Donovan Ferreira, 25, were other newcomers in the T20 squad but were not picked for the one-day games.
Star players Quinton de Kock, David Miller, Heinrich Klaasen, Anrich Nortje and Kagiso Rabada will be rested from the T20 games but will appear in the one-dayers.
Left-arm spinner Keshav Maharaj, who ruptured his left Achilles tendon during a Test match against the West Indies in March, is scheduled to make his return to cricket during the T20 series.
