Mark Williams defeated local favourite Thepchaiya Un-Nooh 8-2 in Bangkok to win the Sangsom Six Red World Championship.
The world number 17 won six frames on the trot from 2-2 to clinch his first title since the World Seniors Championship in 2015 while he pockets a cheque of around £81,000 (3.5 million Baht).
Williams told www.worldsnooker.com: "When I came here I didn’t have any great hopes of winning this. I battled away and I'm so pleased to win an event. Today was the best I played all week. I wasn’t looking to make any big breaks, just to win frames.
"I think over the years I haven’t got any further than the last 16 of this event so I suppose I’ve surprised myself this week. I’ve won a lot of money playing in Thailand and China and I've become a good traveller."
Un-Nooh, who won this invitational title in front of his home crowd two years ago, said: "Mark played very well. I couldn’t take any chances and when I missed he had all the answers."
