Ronnie O'Sullivan stormed into the last eight of the Maplin UK Championship in Telford with a 9-1 victory over world number 21 Mark King.
O'Sullivan has not won a ranking title for 32 months
The three-times champion led 7-1 after a fine opening session on Tuesday morning and completed the rout with breaks of 49 and 40 in the evening.
Also in the quarter-finals is Mark Williams, who overturned a 5-1 deficit to overcome Mark Allen 9-5.
Williams picked up eight consecutive frames to seal an outstanding comeback.
The foundations for the world number 12's win were set on Monday evening, when he took two crucial frames to reduce the arrears to 5-3.
There were far too many unforced errors for my liking and I can't allow myself to say that was good
Williams has endured the worst slump of his career over the past year but the manner in which he kicked on against Allen will give him every confidence of adding to his 1999 and 2002 titles.
"I managed to make two good 50s to go 5-3, otherwise I was close to going out," said Williams, who pocketed match breaks of 59, 57, 47, 48, 54, 54, 52 and 78.
"I don't think my game is quite good enough to win the tournament at the moment, but if I can keep improving I could be here on Sunday."
Allen, who made breaks of 103, 50, 115, 55 and 69, said: "I don't really know what to say, I was diabolical in the second session."
Williams will play Stephen Maguire for a place in the last four after the Northern Ireland Trophy champion beat Preston's Ian McCulloch 9-5.
O'Sullivan faces Jamie Cope - conqueror of John Higgins - after the 22-year-old edged past Barry Hawkins 9-8.
"I can't really allow myself to say that was a good performance," said a modest O'Sullivan, who made breaks of 119, 51, 71, 82, 63 and 49.
"It was a win, but that was about it really.
"There were far too many unforced errors for my liking and I can't allow myself to say that was good.
"The scoreline flatters me massively - Mark didn't punish me and I got a bit of luck."
The 2005 world champion Shaun Murphy brushed aside Stuart Bingham 9-3, having led 5-3 overnight.
Next up for Murphy is 2005 winner Ding Junhui, who rallied late to overwhelm Nigel Bond 9-5.
Marco Fu, this season's London Grand Prix champion, beat Joe Perry 9-2 and faces Mark Selby on Wednesday.
Selby led Dave Harold 6-2 after the first session and wasted little time closing out the win.
