South Korea-born Kiwi golfer Lydia Ko took the golfing world by storm from the moment she became the youngest winner of an LPGA Tour event with victory in the Canadian Women’s Open in 2012 at the age of 15.

She turned pro the next year and didn’t waste any time in climbing up the world rankings. At last year’s LPGA Coates Championship in Florida, Ko entered the final day with a four stroke lead. Even though she surrendered that lead, finishing second behind Na-Yeon Choi, Lydia created history by becoming the youngest world No 1 in golf history, reaching the top aged 17.

She eclipsed the mark set by Tiger Woods, who was 21 when he became men’s world No1 in 1997.
