Fast bowlers Andre Nel and Charl Langeveldt won places in South Africa's 15-man squad to tour Pakistan next week.
Nel and Langeveldt were selected ahead of Dewald Pretorius and Charl Willoughby, who joined wicketkeeper Thami Tsolekile and fast bowler Monde Zondeki as the casualties from the 17-man squad that drew the Test series in England earlier this month.
Left-arm spinner Paul Adams will not be considered for the three one-day internationals, while veteran batsman Gary Kirsten will replace all-rounder Alan Dawson in the squad from which the teams to play in the three Test matches will be chosen.
The selection was a vote of confidence in Graeme Smith's team, who went to England as underdogs and took a 2-1 lead into the final Test. England won by nine wickets to square the series.
The squad named on Monday by the United Cricket Board is scheduled to leave for Pakistan on Sunday.
But the tour is in jeopardy in the wake of South Africa's reluctance to play in Karachi and Peshawar after being advised by their government to avoid the two cities as well as Pakistan's border with Afghanistan.
The Pakistan Cricket Board has declined South Africa's request to move matches from those areas and a UCB delegation arrived in Pakistan at the weekend to assess player security.
Media reports from Pakistan on Monday said the delegation was satisfied that South Africa's tour party would be safe.
However, UCB chief executive Gerald Majola, said the board would make a decision on the issue only after the delegation had submitted its report. The three-man team is due to return to South Africa on Wednesday.
"The UCB delegation are currently in Pakistan and are consulting with the PCB and their security agencies," Majola said in a UCB statement.
"We are aware of reports emanating from Pakistan officials today, but we will only be able to make a clear judgment on security issues once our delegation has returned from Pakistan and submitted their report.
"We are also continuing to consult our government on the matter."
The one-day squad:
Graeme Smith (captain), Paul Adams, Mark Boucher, Alan Dawson, Boeta Dippenaar, Herschelle Gibbs, Andrew Hall, Jacques Kallis, Charl Langeveldt, Neil McKenzie, Andre Nel, Makhaya Ntini, Robin Peterson, Shaun Pollock, Jacques Rudolph.
