World champion Mark Williams admitted he "got out of jail" as he defeated Noppon Saengkham to reach the final of the Hong Rui Ma Yushan World Open.
Williams trailed his Thai opponent 5-2 but recovered to claim a 6-5 victory and set up a final clash with David Gilbert in China.
A total clearance of 142, the highest break of the tournament so far, in the fifth frame was the highlight for Saengkham but Williams showed his class by dominating the closing stages
The Welshman said on worldsnooker.com: "When you're free-rolling you get the rub of the green. When I went 3-2 down, everything went against me.
"At 5-5 I fancied my chances because we were playing for £40,000 for one frame and that's a lot of pressure so I knew he would start feeling it. I got out of jail."
Gilbert is looking to win his first ranking title and he made the perfect start against Barry Hawkins by opening up a 3-0 lead before holding on to win 6-4.
