The 15-year-old opened the LPGA co-sanctioned ISPS Handa Women’s Australian Open with tournament leading 63 at Royal Canberra.
She beat playing partners Yani Tseng by five and Michelle Wie by 11!
Refocused after her history-making New Zealand Open triumph at Clearwater last Sunday, Ko amassed 11 birdies to make an imposing start to the season-opening US$1.2 million LPGA co-sanctioned tournament.
The diminutive right hander opened on the back nine with a bogey five - though that setback was far from an ominous sign.
Ko displayed no signs of anxiety despite featuring in a marquee group alongside world No 1 Yani Tseng and former teenage prodigy Michelle Wie.
