Jin Young Ko Becomes World No. 1

With her maiden major victory at the ANA Inspiration, Jin Young Ko ascended to No. 1 in the Rolex Rankings for the first time in her career. Ko didn’t have much work to do since joining the Tour in 2018, already ranked at No. 18 in the world. She’s continued a steady climb between October 2017 and April 2019, in which she won four times on the LPGA Tour. Ko’s final leap came with her victory at Mission Hills, which marked her second win in three weeks, and lifted her from No. 5 to No. 1 in the world. 
Ko is the third player to hold the top spot in the Rolex Rankings in 2019. She joins Ariya Jutanugarn, who held the No. 1 position from October 2018 to March 2019, and Sung Hyun Park, who held the ranking for the last five weeks.
The 2018 Louise Suggs Rolex Rookie of the Year also currently sits atop the money list, the Race to the CME Globe standings, the Rolex Player of the Year race, and leads the Tour in scoring average and greens in regulation
