Mark Williams secures World Open final clash against David Gilbert

Williams had begun the semi-final reasonably well, taking an early 2-1 lead, but proceeded to lose the next four frames before recovering to put a run together - including breaks of 56 and 64 in frames nine and 10 - to take the match.

Saengkham, the World Under-21 champion in 2009, produced the moment of the match - and the season so far - with a break of 142 in frame four but, having fashioned a near-unassailable lead, fell short against the world champion.

David Gilbert had earlier reached the final of the World Open as he beat Barry Hawkins 6-4.

The world number 29 moved to a 3-0 lead with breaks of 101 and 54, but Hawkins clawed back two frames to close the gap before Gilbert extended his advantage.

Gilbert had a chance to wrap up the match in the ninth frame but missed the green, allowing Hawkins to clear for 5-4.

He finished it off in the tenth, though, with a break of 45.

“I’m over the moon,” Gilbert said afterwards. “For 90% of the match I played great, then the wheels came off towards the end and someone nearly had to pick me up off the floor."

He added: "It would mean everything to me to win the title, the only thing I’ve always wanted to do is go home a winner. I haven’t won anything since the Tamworth Open about 25 years ago. To be in the top 16 as well would be where I’ve always wanted to be."
