England won the toss and decided to bowl in a rain-delayed second one-day international against South Africa at Kingsmead on Friday.
The match was reduced to 45 overs a side.
England captain Eoin Morgan said the weather conditions and the possibility of interruptions had influenced his choice to bat second. "Chasing later on is an advantage if there's a bit more rain around," he said.
England named an unchanged team despite losing the first game in the three-match series by seven wickets in Cape Town on Tuesday.
"This tour is about opportunity and winning," said Morgan.
"The guys under-performed and were a bit rusty so we're hoping for a marked improvement in this game."
