Devine, making her return after a gap of two-and-a-half years, struck an aggressive 131-ball 145 to help New Zealand post 320 for five after being sent into bat at the DRIEMS Ground, Tangi. This is her maiden century in one dayers.
Defending the total, left-arm pacer Siam Ruck (4/31), spinner Morna Nielsen (3/34) and Lea Tahuhu (2/27) starred with the ball to help Black Caps bundle out the Proteas for 170 runs with nine overs to spare.
Devine, who missed last month's Rose Bowl series against Australia with injury, decorated her innings with 13 fours and six sixes to surpass her previous best score of 74 against the Aussies.
South African run chase never really got off as they lost wickets at regular intervals. Opener Savanna Cordes was dismissed on the third ball of the innings after she was trapped leg before by Tahuhu for nought.
South Africa then lost other opener Yolandi Potgieter (8) in the sixth over while Marizanne Kapp (10) too did not last long as the Proteas were left reeling at 43 for three.
Skipper Mignon du Preez (29) and Cri-zelda Brits (23) then tried to resurrect the innings with their 24-run stand for the fourth wicket but Nielsen struck twice in successive overs to dismiss both the batswomen.
The left-arm spinner further compounded the misery when she had Chloe Tryon (4) caught behind by wicketkeeper Katie Perkins. MORE
