Ariya is the overall champion

The highlight on the final day of the event held at the 6,743-yard Royal Hua Hin Golf Course was the contest for the overall championship, which turned out into a duel between the 13-year-old girl Ariya and Thitiphun Chuayprakong, three years her senior.

Ariya, the former Junior World champion, put her male counterpart in the shade by blasting a blistering final round of six under par 66 for an aggregate of 282, three strokes better than Thitiphun.

"I am very glad to clinch the championship with the six-under-par score. I am happy although I should have done better," she said.

"The overall competition is fun and I gained plenty of experience," said a delighted Ariya, the younger sister of Junior Open champion Moriya.

Thitiphun, who won this year's Lion Cup tournament in Singapore, took home the Boys' Class A title, while Chirapat Jao-Javanil won the Girls' Class A division with the total score of even-par 288.

Atiwit Janewattananond, who posted the total score of five under par 293, claimed the Boys' Class B title. Wad Phaewchimpplee clinched the win in the Girls' B category.
