The 17-year-old's climb to the top of the world rankings has been phenomenal, and she shows no signs of slowing down now that she's reached the summit.
Sunday's win at Royal Melbourne was Ko's ninth professional title, and one that demonstrated great consistency, with the Kiwi notching up rounds of 70-70-72-71 to secure a two-shot victory.
The Korean-born teenager has revealed that staying calm and patience was crucial in her bid for the title.
“I think patience is probably the biggest [key]," she explained. "You’ve got to hit good shots but I think patience was the biggest one that you needed to have.
"Here, there are so many putts that can be so close but then end up being a couple of feet by and you look back and think ‘how did I make that bogey?’ but it’s kind of easy to do. It’s hard to make birdies but so easy to make bogeys or worse.
"I think just patience, that’s what I tried to have. I was talking to David (Leadbetter) yesterday and he said ‘Lydia, you’ve just got to have that patience and just wait for the birdies to come’."
Despite all of her success, Ko says that participating, rather than only winning, is what she enjoys the most.
"It’s cool that I’m actually on the LPGA as a tour member as a 17-year-old and just to be one of the youngest tour members is another special thing but to be able to win here is amazing," she explained.
"It’s been so much fun playing here. It’s pretty awesome. I feel so fortunate that I can play these great tournaments at these great golf courses and travel around the world. That’s the most important thing, that I’m having fun and I’m getting all these great opportunities. Winning is another great thing but just being able to play here is my favourite thing.”
