Judd Trump showed some ominous form with three centuries as he beat Fraser Patrick 6-3 to reach the last 16 of the UK Championship at York's Barbican Centre.
The Bristolian surged into a 4-0 interval lead and though his opponent came back into the game, he had enough of a cushion and was always comfortable.
Trump made an 85 break in the first frame and when he made 129 and 130 in the next two, it looked like being a short afternoon's work.
Patrick was in first with 59 in frame four but could not close it out and Trump nicked it for a 4-0 lead.
The interval came at a good time for Patrick and he got on the board with a 66 break and then closed further to 4-2.
The players shared the next two frames with half-centuries before Trump wrapped up the game with his third century, a 104.
Trump's attitude has often been criticised but this season he has won the Australian Goldfields Open, his first ranking tournament win for nearly two years, and reached the final of the recent Champion of Champions event in Coventry.
A delighted Trump said: "I've put the work in a lot more than I have done in the past, probably 50% more.
"That's just because of my lack of results in the last couple of seasons, I felt like I'd stood still and everyone else had moved on around me.
"When I'm really confident I don't practice that much because there's no point boring yourself. But after Australia I played five hours a day solid, phone off and just practice.
"I'm trying to concentrate on my snooker and forget going out and other stuff like that," added Trump.
