Following her first major victory at the 2019 ANA Inspiration on Sunday, Jin Young Ko has ascended to No. 1 in the Rolex Women’s World Golf Rankings. Her three-stroke win at Mission Hills Golf Club in California vaulted her from fifth to the top of the standings.

 

“Reaching World No. 1 is exciting and I cannot believe that I have achieved this honour,” said Ko. “I always keep my focus on the golf course and on my playing, but to win a major championship and be called the best player in the world is absolutely a great honour. I want to thank my family, my caddie and my manager for all of their support.”

 

Ko is the fifth player from the Republic of Korea to reach World No. 1, following Inbee Park, Sung Hyun Park, So Yeon Ryu and Jiyai Shin. She is the third player to hold the title of World No. 1 in 2019, joining Ariya Jutanugarn and Sung Hyun Park, who was No. 1 for the previous five weeks.
