England claimed a series victory after the fifth One-Day International against South Africa was called off due to persistent rain at Kingsmead on Friday.
The match was abandoned at 5 p.m. local time (1500 GMT) without a ball being bowled.
The outcome means that England secure the series 2-1, after the first match was also washed out, and become only the second country to win a bilateral One-day series in South Africa.
Australia achieved series wins in the 1996/7 and 2001/2 seasons.
