England 159 for 3 (Edwards 84*) beat South Africa 157 for 5 (Terblanche 81) by seven wickets
Charlotte Edwards anchored England to a convincing victory over South Africa in the third ODI at the Laudium Oval in Tshwane, near Pretoria. England now lead the five-match series 2-1.
Edwards finished with 84 not out, including eight fours from 126 balls, and received good support from Clare Taylor (37) - they put on 81 as England swept past the South African total with nearly 10 overs to spare.
The South Africans had earlier struggled against tight bowling from Jenny Gunn, whose 10 overs cost only 19 runs, and Rosalie Birch, who took 2 for 26 in her allocation. Helen Wardlaw, Birch's fellow offspinner, also took two wickets but proved a little expensive - her 10 overs cost 50 runs.
Laura Newton started quietly for England, grafting to 13 from 51 balls in an opening stand of 46 with Edwards, and later Clare Connor, England's captain, faced 26 balls before falling for 7. But Edwards had all but won the match by then.
