HAINAN, China -- Shanshan Feng shot a 2-under 70 in the final round to win the Blue Bay LPGA by one stroke.
With the win, Feng was projected to become the first top-ranked golfer -- male or female -- from China. That became official on Monday.
"I finished first in China, so I actually claimed the world No. 1 in front of all the people at home," Feng said Saturday after finishing on 9-under 279. "I'm really happy about that, and I hope all the Chinese are going to be watching me. ... Hopefully there will be more Chinese getting on the tours and more world No. 1s coming up from China."
Feng, who won last week in Japan, became the first back-to-back winner of 2017.
Thailand's Moriya Jutanugarn (70) was second at 8 under, just one shot behind Feng, after narrowly missing a birdie attempt on the 72nd hole.
"I was just trying to give myself a chance," Jutanugarn said of her final putt.
Current top-ranked Sung Hyun Park (72), Ashleigh Buhai (73) and American duo Jessica Korda (71) and Megan Khang (68) all tied for third.
