Lydia Ko has moved to number four in the world rankings following her first win as a professional golfer in the weekend, capturing the Swinging Skirts World Ladies Masters US$800,000 event in Taiwan.
Ko jumped from sixth to fourth in the rankings, leapfrogging Korean So Yeon Ryu. Ko won the event at the Linkou Miramar Golf Club in Taipei after surging past Ryu on the final nine holes to win by three shots.
Ko took away $US150,000 ($NZ181,000) for the victory, along with $US8,000 she won in the tournament's skins event last week.
Korean Inbee Park will finish the year as world number one with Norway's Suzann Pettersen in second spot. American Stacy Lewis is world number three.
The 16-year-old will begin her 2014 campaign at the Bahamas Classic from January 23 - 26, where she must attend a mandatory rookie's session, before she will return home to defend her title at the ISPS Handa New Zealand Women's Open in Christchurch from January 31 - February 2.
