England again stuck with a winning team as they target one-day international series victory over South Africa.
Victory at SuperSport Park would give Eoin Morgan's tourists an unassailable 3-0 lead and put a 5-0 whitewash on the agenda.

South Africa made one change after losing again at Port Elizabeth on Saturday, all-rounder David Wiese coming in for middle-order batsman Rilee Rossouw.
