Golf: A 14-year-old New Zealand amateur has become the youngest winner of a professional tour event with victory in the New South Wales Open.

Lydia Ko broke the record of 15 years and eight months set by Japan's Ryo Ishikawa as the New Zealander shot a three under par final round of 69 to finish the tournament on 14 under, four strokes clear of Wales' Becky Morgan at the Oatlands Golf Club.

Ko, a school student in Auckland who plans to take part in the Australian Masters and the LPGA Australian Open, moved to New Zealand from South Korea in 2003.
