No matter what happens at this week's LPGA Tour event in New Jersey, either Ariya Jutanugarn or So Yeon Ryu is projected to move to the top of the rankings.
Ryu is the only one of the trio playing this week and if she finishes third or better she has a chance to leapfrog Jutanugarn and become the new world number one.
Ko has stood atop the rankings for 84 consecutive weeks but is currently taking a break from tournament play.
Meanwhile, fellow Kiwi Danny Lee is tied for 48th after the opening round of this week's PGA Tour event in Ohio.
