Thailand's Jeeno Thitikul bagged her fourth title of the year with a three-shot victory at the LPGA Tour's Lotte Championship in Hawaii on Sunday.
The world No 2 carded six birdies in a four-under-par 68 to finish on 21 under par at Hoakalei Country Club on Oahu.
South Korea's Yoon In-a was second on 18 under after also finishing with a four-under-par 68.
Thai star Jeeno suffered a scare coming down the stretch with a double-bogey six on the 16th that dropped her to 19 under.
But back-to-back birdies on 17 and 18 restored her cushion and averted the possibility of a playoff.
"I totally have no idea how I did that," Jeeno said of her birdie-birdie finish. "It was a really good battle with In-a. She played incredible on the front nine.
"I knew I had to focus on my game. The 16th was terrible, a terrible hole for me. But I just tell myself that it's two holes left and everything can happen."
Japan's Miyu Yamashita finished in third place on 17 under after her final-round 67, one shot ahead of fourth-placed Auston Kim of the United States.
China's Michelle Zhang and Sweden's Maja Stark shared fifth place on 15 under, six off the lead.
