South Africa captain AB de Villiers compiled a superb century to lead his side to an easy six wicket win over New Zealand in the opening one-day international at Westpac Stadium on Saturday. De Villiers, in deft touch, was not out for 106 with Faf du Plessis on 66 as South Africa overhauled New Zealand's 253 for nine with 28 balls to spare. On a ground with a history of favouring the side batting second, New Zealand captain Brendon McCullum won the toss, elected to bat first and never seriously threatened from there as his batsmen failed to gain momentum. Although the target was not immense, South Africa wavered at the start of their innings with Hashim Amla (8), Graeme Smith (9) and Jacques Kallis (13) falling in quick succession to be 35 for three by the 10th over. But from there de Villiers steadied the run chase and they slowly and surely reeled in the New Zealand total.
