Danielle Kang climbed to No. 2 in Monday’s release of the Rolex Women’s Rankings, making her the highest ranked American in the world.

With her victory Sunday at the Drive On Championship, Kang moved up two spots, leapfrogging former No. 2 Nelly Korda, who tied for 40th in Toledo, Ohio, and slipped to No. 3. Kang also moved over Sung Hyun Park, who slipped a spot to No. 4.

Kang still trails No. 1 Jin Young Ko, who has now reigned atop the world rankings for 54 consecutive weeks. Ko finished 20th in Sunday’s Jeju Samdasoo Masters on the Korean LPGA Tour. Ko hasn’t played an LPGA event in more than eight months, since the season-ending CME Group Tour Championship last year. Still, Ko built a substantial lead in the world rankings with five worldwide titles last year, four on the American based LPGA, with two of those major championships. She sits 2.13 average world ranking points ahead of Kang, which is the about same differential between Kang and world No. 16 Ariya Jutanugarn.

The Rolex world rankings and its 104-week rolling window were temporarily amended during the coronavirus pandemic to focus more on an individual’s playing schedule, rather than the actual calendar.

Rankings for an athlete continue to be computed on a 104-week rolling period, but that 104-week rolling period differs based on how much an athlete plays while the modification is in place. Weeks when an athlete does not compete does not count towards her individual 104-week rolling period. Her individual points, average points and divisors will not change or age when she doesn’t play. However, her overall position on the rankings could shift based on the performance of other athletes who are competing.
