Lydia Ko is remarkably unfazed by the prospect of her 82-week stranglehold on the No.1 women's world golf ranking ending this weekend.
A winless run stretching back 10 months has left the 20-year-old Kiwi on the verge of losing her throne at the Kingsmill Championship in Virginia.
Ko hasn't won in her last 18 starts, and only .23 points separate her from No. 2 So Yeon Ryu (Korea) in the world rankings, with a further .02 points separating Ryu from No. 3 Ariya Jutanugarn (Thailand).
Ryu has placed in the top 10 in her last 10 tournaments while Jutanugarn is the Kingsmill defending champion.
But Ko is taking a philosophical approach into the $US1.3 million ($NZ1.9 million) championship in Williamsburg.
"I don't really look at the rankings myself," she said.
"I kind of know these things through media and when people tell me 'Hey it's getting close. It could change this week'."
Ko says the quality of golf and the amount of talent on the LPGA Tour is impressive, and she knows she'll have to work hard.
"It's not just about three players. Not just about the big three. It's about the whole tour," she said.
"I just got to focus on the round, the shot in front of me, and not get too carried away about the results and the rankings. Just got to focus on me."
Ko has never finished outside the top 20 at the Kingsmill Championship, her best finish coming three years ago when she took fifth as a rookie.
