The 17-year-old stormed to three tour titles in her maiden season as a pro, following up victory at the Swinging Skirts LPGA Classic with further wins at the Marathon Classic and the season-ending CME Group Tour Championship.
Further impressive displays at the Women???s PGA Championship and last month???s Coates Golf Championship lifted the New Zealander as the world???s best, with Ko surprised by her rapid rise up the rankings.
???I had such a good rookie year,??? the teenager said. ???It was more than I expected and more than I???d planned.
???It was kind of a dream come true, the season last year, finishing well and making it to the CME Group Tour Championship.
???To back it up with another great year is going to be tough, but I???ve set it off well with two top ten finishes so am just going to try and work my way up and give myself a lot of opportunities.?????
Whilst talk will be about whether Ko can break Morgan Pressel???s record as the youngest ever women???s major winner at April???s ANA Inspiration, the New Zealander has several tournaments to prepare at before appearing at Mission Hills.
The teenager will make her second appearance at next month???s star-studded HSBC Women???s Champions event, looking to build on to last year???s visit to Singapore.
Ko ended 15th last time around, eight strokes adrift of Paula Creamer, but is confident of challenging for victory this time around.
???I felt like last year I did leave a couple of shots behind, so I do feel like I can win. Being my second time playing here, I???ll be a little bit more used to the course.
???It can get a little breezy there and because of the big greens you really have to shoot for small targets, so I???ll be going out there trying to play good golf.
???The world???s best players are there, so everybody is going to be super excited and hoping to have a trophy at the end of the week.
