Thai golfer Pornanong Phatlum led from the front to scoop her first LPGA tour victory at the HSBC-sponsored Brasil Cup event in Rio de Janeiro.
The 22-year-old carded a tournament record score of -13 to become the fourth different winner from four different continents in the event featuring the most international field ever assembled in South America.
Phatlum's nerveless four shot win over Taiwan player Amy Hung means that Asia joins South America, North America and Europe as winners of the tournament in its short history.
Thirty players from fifteen different countries teed off at Itanhanga Golf Club, Rio, for the two day event and, having been joint leader overnight with a score of 66 she fired five birdies on the front nine to march to victory.
She said: "I'm so excited today. I played really well and I played my own game. I'm just very happy."
Phatlum's brother Pornpong was her caddy for the week and she added: "We just had fun today and he really helped me to concentrate."
HSBC Global Head of Sponsorship and Events Giles Morgan said: "As a global sponsor of golf it's incredibly rewarding to see players from all corners of the globe winning our tournaments.
"The LPGA Brasil Cup presented by HSBC was the most international field ever assembled in South America and a fourth different winner from four different continents tells you everything you need to know about the growth of golf on the global stage."
