Lydia Ko
That comes on the back of finishing tied for 17th at the LPGA Championship, which ended in New York on Monday.
The 16-year-old from Gulf Harbour has played only 18 professional events since her debut at the New Zealand Open three years ago and is the biggest mover on the rankings in the last year, up 160 places.
Ko is also well clear of the field in the world amateur rankings. She is on 2354.03 average points, more than 600 ahead of Australian Su-Hyun Oh (1700.00).
Ko will play the Walmart NW Arkansas Championship starting on June 21 before her fifth major, the US Open at Seboneck Golf Club in New York from June 27-30.
