BIRMINGHAM, England (Reuters) - Captain Kane Williamson's patient unbeaten century led New Zealand to a tense four-wicket victory over South Africa in a low-scoring Cricket World Cup match at Edgbaston on Wednesday.

Chasing 242 to win a match reduced to 49 overs a side by rain, New Zealand looked set to comfortably reach the target with Martin Guptill and Williamson at the crease.
