Top players from three tours will tee off at the PTT Thailand LPGA Masters at Bangkok's Panya Indra Golf Club today.
The three-day event is the season finale of the Thai LPGA Tour 2018 and sanctioned by the Thai LPGA, China LPGA and Australian LPG tours.
The four-million-baht tournament has attracted 114 players from 15 countries who will be vying for the winner's cheque of 600,000 baht.
The Thai challenge is led by in-form teenage amateur Arpichaya "Piano" Yubol and defending champion Saranporn Langkulgasettrin.
Arpichaya, 16, is leader on the money list and will be seeking her sixth consecutive title on the circuit.
"It's exciting to win five titles in a row. I am a bit nervous playing as the leading player on the Order of Merit,'' said the Saraburi native.
"I know that many people are expecting me to play well so I will do my best to not disappoint them. I believe I can finish in the top 10."
Saranporn, 19, who was the 2017 money winner on the Thai LPGA Tour, had four wins at home and abroad last year.
This year, the Phuket native has won the Hong Kong Ladies Open and Sun Car Zhangjiagang Shuangshan Classic in China.
"It's good to come back to Thailand and also defend the title," she said.
"I will try my best and have fun with my game. I won't put extra pressure on myself. If I fail to the win the title, I hope another Thai keeps the trophy in Thailand."
The other Thai players in the field include Wanchana Poruangrong and Supamas Sangchan.
As for the international contingent, China's Li Jiayun is among the pre-tournament contenders.
The 28-year-old led her country to silver in the women's team event at the 2010 Asian Games in Guangzhou.
Li, from Guangxi, turned professional the following year and has won the 2014 Shanghai Classic and the 2016 Beijing Ladies Classic.
"I like Thailand and really enjoy Thai food. I waited a whole year to come back here. Last year I had two good rounds but my final round wasn't good enough," said the Chinese.
"This year my goal is to have three great scores to help me finish in the top 10."
The Australians are spearheaded by Amy Walsh who has visited Thailand on several occasions.
"It will be a great test of golf with the three tours coming together," she said.
"I played the course in 2014 [at the Thailand Amateur Championship] so I'm interested to see how different it will play and how far my game has come since then.
"I expect the competition to be tough as Thai golf is very strong at the moment. Personally, I feel like my game is starting to come together and it will be an enjoyable week. I've been in Europe for the last few months which will hopefully have prepared me for this event."
The final two rounds tomorrow and on Friday will be shown live on True Sport HD 2 from 1.30pm. Tickets are available at the course and priced at 100 baht for a three-day pass. Entry is free for spectators aged under 18 and over 60.
