South Korea's Jin Young Ko was ranked No. 1 in the world Monday for a record-setting 159th week, and rising star Rose Zhang is now in the top 50.
Ko remained atop the Rolex Women's World Golf Rankings after a tie for 20th at this past week's KPMG Women's PGA Championship, surpassing the 158 weeks spent at No. 1 by Lorena Ochoa of Mexico from 2007 to 2010. Ko, a 15-time winner on the LPGA Tour, has held the No. 1 spot five different times since April 2019. This is the 27-year-old's sixth consecutive week there.
