Former world champion Mark Williams safely secured his passage through to the quarter-finals of the Rileys Club Masters with a battling display against Alan McManus.
The two-times Masters champion trailed 2-1 to his Glaswegian opponent, winner of the tournament in 1994, who had edged ahead with breaks of 63 and 54.
But Williams, who has won just one ranking match all season in a decline which has seen him fall from grace from number two in the world to provisionally 14th, rediscovered his touch to triumph 6-3.
The Welshman added to his opening frame break of 88 to compile further runs of 67, 54, 116 and a splendid 66 after trailing 65-0 which sealed victory and a quarter-final berth.
McManus looked likely to reduce the deficit to 5-4 on a break of 64, but the world number 10 missed a routine red and Williams capitalised to set up a dream last-eight showdown with tournament crowd-pleaser Jimmy White.
Victory was sweet for Williams after a run of form which has threatened his place in the top-16, a far cry from his World Championship winning seasons in 2000 and 2003.
"It's given me a little bit of boost for the rest of the season," said Williams.
"I felt I played okay in the match. I played a bad shot when I had a chance to finish the match, but I finished well.
"I'm expected to finish in those situations, but when you've not been playing well it's hard.
Williams admits he has been playing superb in practice and is confident of an unlikely win this year's final at the Wembley Conference Centre.
"I felt confident again," added Williams. "There was a lot of pressure for me to win this match.
"I've been playing superb in practice, but I just need it to click in matches. That's probably the best I've played all season. It's just good to get a win."
