Ariya Jutanugarn became the first Thai golfer to win a major championship by taking the Ricoh Women's British Open title, while Ireland's Leona Maguire fell out of contention on the final day at Woburn.
The 20-year-old missed out on major glory when she dropped shots at each of the last three holes after leading by two strokes with three to play at the ANA Inspiration in California in April.
But the big-hitting Thai made amends at Woburn. Ariya went into the final round holding a two-shot lead and a closing level-par 72 left her three clear of the field on 272, 16 under.
Playing partner Lee Mi-rim of South Korea (73) and American Mo Martin (70) shared second place while Stacy Lewis of the US also carded a 70 to take fourth spot on 277.
Cavan's Maguire couldn't follow up yesterday's heroics when she hit five birdies for a 68 to enter today's play on the fringes of the top ten.
The Slieve Russell golfer mixed four bogeys with one birdie on her way to a 75 for a share of 25th and the Smyth Salver award as leading amateur.
"For me it was hard today," Jutanugarn told BBC Sport. "I felt a little bit nervous at times.
"My mother cried at the end. She said thank you, and that made my day. I think this victory is really important for me and Thai golf. I hope I can inspire some players in Thailand."
