World champion Mark Williams reeled off three frames in succession to reach the final of the LG Cup with a 6-3 win over Ken Doherty on Saturday.
Williams was pleased with his improved form
The Welshman, who began the new season heading the world rankings, now faces Scotland's John Higgins in Sunday's final.
After recovering from 2-0 down to be level at 3-3, Williams produced breaks of 72, 66 and 86 to finish the match, with Doherty unable to score in either of the closing two frames.
The Cardiff player has struggled all week in Preston, but was delighted with the way he performed against Doherty, especially the last three frames where he racked up an amazing 276 unanswered points in just under 33 minutes.
"That was better," said a relieved Williams. "I've done quite a lot of work with Terry (Griffiths) on the practice table the last couple of days. I felt relaxed, but it all seemed to click tonight."
Higgins had earlier secured his place in the final with a comprehensive victory over John Parrott.
The world number four raced into a 4-0 lead at Preston's Guild Hall and eventually wrapped up the match 6-2.
Higgins, who is aiming to win his first ranking title in two years, notched up breaks of 61, 58, 81 and 52.
Parrott had surprised fans by reaching the last four of an event for the first time since 2001.
"I feel a 100 times better than I have for the last two years," said
"I'm hitting the ball well and I feel I've got to prove a lot this year.
Whoever I play in the final, I think I'm in with a great chance," he said.
