Dussavi saved par on the final hole to sign off with an 8-under-par 208 while her close rival Budsabakorn made a bogey on the same hole to miss a chance for play-off at the par-72, 6,439-yard landscape.
“I haven’t played like this for a long time and feel great to get back into the winning circle again,” said Dussavi, whose previous title was at Mae Jo Golf Resort and Spa in Chiang Mai two years ago.
“I want to dedicate this win to my parents, who always support me, no matter whether I win or not. I hope to carry this winning momentum going into the Chiang Mai leg next week,” said Dussavi, who received a cheque of Bt142,000.
Parinda and Budsabakorn, after their final round 69 and 72, were a shot behind at 7-under. Each player received Bt78,730. They will enter the seventh leg of the 2017 Thai LPGA Tour in Chiang Mai, which starts on Wednesday.
