Not only did the 15-year-old become the youngest winner in professional golf history when she picked up the NSW Open title but she became the youngest to win on the LPGA Tour when she beat nine of the world's top 10 to claim the Canadian Open by four shots.
To add to her list of achievements, Ko also finished as the leading amateur on her major debut at the US Open and again at the British Open, became the first Kiwi to win the US Amateur Championship and the youngest in history to win the Australian Amateur.
She finished her year in style by winning the individual competition at the Espirito Santo World Amateur Team's Championship in Turkey and, while it falls out of the judging period, has followed it up with a win at last week's New Zealand Women's Open.
This is not to denigrate the achievements of others. Far from it.
They have all achieved at the highest level.
Bond and Murray would be worthy winners of the Supreme Award.
The men's pairs combination went through their Olympic cycle unbeaten, even scaring off their main rivals from Great Britain who abandoned their campaign and joined a four, and won the Olympic final in terrible conditions by nearly half the length of Eton Dorney.
It's another reason why rowing guru Dick Tonks should win the Coach of the Year award - although Carrington's mentor Gordon Walker deserves special mention in a sport recently torn apart by political infighting - and hugely decorated swimmer Sophie Pascoe is favourite in the Disabled Sportsperson of the Year category.
Ko is a shoo-in for the Emerging Talent award. It's just she probably deserves more than that.
And the finalists are ...
Sportswoman of the Year: Lisa Carrington (canoeing), Valerie Adams (athletics), Lydia Ko (golf), Sarah Walker (BMX).
Sportsman of the Year: Mahe Drysdale (rowing), Andrew Nicholson (equestrian), Simon van Velthooven (cycling), Richie McCaw (rugby).
