Lydia Ko officially ascended to No. 1 in Monday’s release of the newest Rolex Women’s World Golf Rankings.
With her tie for second Saturday at the Coates Golf Championship, Ko barely overtook Inbee Park, ending Park’s most recent 14-week reign at No. 1. Ko is just three hundredths of a point in front of Park, who overall has spent 73 weeks atop the world rankings.
With No. 1 Ko, No. 2 Park and No. 3 Stacy Lewis all in the field at the Pure Silk Bahamas Classic this week, the No. 1 ranking will be up for grabs again. Ko sits atop the rankings at 9.70 average points. Park is at 9.67 and Lewis at 8.83.
“I think it's going to be really hard to catch Lydia with the points system,” Park said. “She hasn't played that many events. Her averages are really good, so you have to play really good from now on in.”
The world rankings are based on points accumulated over a two-year rolling window, with the points average based on a player’s number of starts, with a minimum divisor of 35 starts. Ko’s points are divided by her 43 tournament starts over the last two years, Park’s by 55 and Lewis’ by 56. While Ko is beginning just her second season as an LPGA member, her 43 starts are the same as Karrie Webb, who is No. 9 in the world.
