South Africa on a roll

Having won the first three matches, South Africa have an unassailable lead in the five-game one-day international series against New Zealand. But having been humbled by the Black Caps in New Zealand last time round, there is little doubt that the South Africans have their eyes set on completing a 5-0 series whitewash.

Graeme Smith´s side are 4/6 (1.66) to win the fourth match in the series, a day-nighter to be played at Kingsmead in Durban on Friday. The New Zealanders, who have not played that badly in each of the first three matches, are 11/10 (2.20) to win and restore some pride, a word mentioned by captain Stephen Fleming after the latest defeat.

As so often over the past few years, South Africa´s lower order completed the job, with Justin Kemp already proving to be a real thorn in New Zealand´s side. With no Test matches to be played on this tour, they have thrown themselves into the one-day games, not least because they travel to Australia for a series in December.

For New Zealand, victory in one of the two remaining matches - the last is at Centurion on Sunday - would be a lift to their morale as they prepare for home one-day international series against Australia and Sri Lanka.

Stephen Fleming tops the betting at 3/1 (4.00) with bet365 to be his side´s top scorer at Kingsmead, followed by Scott Styris and Nathan Astle at 9/2 (5.50). Fleming´s opposite number Graeme Smith is the 100/30 (4.33) favourite to head the South Africa runscorers, while Jacques Kallis is 7/2 (4.50), Herschelle Gibbs, top scorer in the last game, is 4/1 (5.00) and AB de Villiers is 5/1 (6.00). Justin Kemp, who has ruined a couple of New Zealand´s best chances, is a 13/2 (7.50) bet.

New Zealand have plenty of spirit but it is hard to see South Africa being stopped now they are on such a roll, partly because they have several match-winners in their side.
