John Higgins needed just 10 minutes to seal a 13-4 win over Fergal O'Brien and reach the quarter-finals of the World Championship at The Crucible.
Higgins scored heavily at almost every opportunity
Higgins resumed with a commanding 12-4 lead after an outstanding display in the second session.
O'Brien battled gamely to close his arrears, but a misjudged safety shot let the in-form Scot back to the table.
And Higgins needed no second invitation as he set up a meeting with former champion Ronnie O'Sullivan.
Higgins' form in the second session on Sunday marked him out as a genuine contender for the title.
Resuming 6-2 behind, O'Brien closed the gap with an 85 but Higgins accelerated away by winning five of the next six, including breaks of 98, 135 and 84.
And Higgins ended his superb display with a 100 in the last frame of the session.
I felt I wasn't going to miss
Higgins was in excellent touch during his break-building, while his safety play tied the battling O'Brien in knots on several occasions.
The Scot said his superb form was partly thanks to a new and more confident mental approach.
"It was good to feel like that again - it's been a little while," he said.
"I felt I wasn't going to miss. I feel my game is there and I'm just trying to keep myself focused and calm.
"In the past, I've looked at the draw too much, but now I'm just trying to get focused on every match. If I play well, I have every chance of winning."
O'Brien was magnaminous in defeat, admitting he had been thoroughly outplayed.
"John was brilliant in the second session, it was fabulous stuff," he said.
"It was good to watch on one level because it gives you good motivation to go back and improve because that's where the bar is.
"It's all good experience and it beats watching someone else being beaten on TV! I felt I was playing well but I ran into John when he was flying and in the blink of an eye he was gone."
