South Africa have kept their victorious squad intact for the remaining three one-day internationals against West Indies.

Graeme Smith's team won the first game in the five-match series by 209 runs in Cape Town on Sunday, and the second by 16 runs in Port Elizabeth on Wednesday.

"The team have performed superbly so far in the series and we don't see any need to make changes," selection convenor Omar Henry said in a United Cricket Board media release.

"We are also mindful of retaining some continuity as this is, in effect, the start of a series of 11 one-day internationals on the trot if you take into account the New Zealand tour."

South Africa leave for New Zealand on February 7 to play six one-dayers and three Tests.

The third one-day international between South Africa and the West Indies will be played in Durban on Friday.

South African squad: Graeme Smith (captain), Mark Boucher, Boeta Dippenaar, Herschelle Gibbs, Jacques Kallis, Lance Klusener, Albie Morkel, Andre Nel, Makhaya Ntini, Robin Peterson, Shaun Pollock, Ashwell Prince, Jacques Rudolph, Morne van Wyk.
