Temba Bavuma has retained the Proteas ODI captaincy ahead of a crucial three-match series against world champions England this month.
New white ball coach Rob Walter will only officially start in his role on 1 February, but he is understood to have played a key role in the selection of this 16-man squad.
Shukri Conrad, named Test coach this week, will oversee the series until Walters joins. The series will count towards ICC Super League points, and the Proteas are desperate to win as many matches as possible - they have five left - in an effort to finish in the top eight and secure automatic qualification for the 2023 World Cup in India.
They are currently 11th and looking increasingly likely to have to play a separate qualifier tournament in Zimbabwe in mid-year to secure their spot in the 10-team World Cup.
