Ariya Jutanugarn claimed the first major championship of her career on Sunday when she won the Ricoh Women's British Open at Woburn, England.
The 20-year-old from Thailand shot even-par 72 in the final round and finished at 16-under 272 on the Marquess Course. She won by three strokes over South Korea's Mirim Lee and American Mo Martin.
Jutanugarn also became the first golfer from Thailand -- male or female -- to win a major title.
"I think it's really important for me and for Thai golf, also," Jutanugarn said afterward. "Like my goal, I really want to win a major and I did. I'm really proud of my achievement because I accomplished my goal this year."
Jutanugarn was cruising toward the victory with a six-shot lead midway through the final round before Lee made a charge. She picked up five strokes in a four-hole stretch as she sank three birdies while Jutanugarn had a double bogey on 13.
"On 13, I'm like, 'Oh, what's wrong with me?'" Jutanugarn said. "But after that, I'm really like be patient and I can come back really good."
Jutanugarn held a one-stroke lead entering the par-3, 17th hole and then gave herself a cushion by making a key 20-foot birdie putt en route to winning her fourth tournament of the season.
Lee, who shot an opening-round 62 to match the tournament record, bogeyed 18 and finished with a final-round 73.
"I really had fun," Lee said afterward. "That was the most important thing. I had fun throughout the whole thing."
Martin, who won the British Open two years ago, shot a 2-under 70 on Sunday. American Stacy Lewis (70) finished fourth at 5-under 277. Australian Karrie Webb and South Korea's Ha Na Jang -- who both shot 71 -- and Scotland's Catriona Matthew (73) tied for fifth at 279.
World No. 1 Lydia Ko of New Zealand finished in a tie for 40th place at 1-under 287. She shot 74 on Sunday.
Moriya Jutanugarn, the 22-year-old sister of Ariya, shot 75 and finished in a tie for 43rd place at even-par 288.
