Kilkenny's David Morris has beaten David Gilbert 6-2 to move into the last 16 at the Coral UK Snooker Championship in York.
However, Ken Doherty's interest in this year's event is over after he was beaten 6-1 by Ricky Walden
World number 62 Morris followed up on his stunning victory over world champion Mark Selby in the previous round with an impressive showing over world number 34 Gilbert, after opening up an early 4-0 lead over the Englishman (61-60, 92-38, 66-10, 76-0).
Gilbert rallied to pull back the next two frames (80-61, 63-14) before Morris made a 65 break to go 5-2 in front (70-4) and went on to book his spot in the next round by winning the eighth frame 55-2.
For Ken Doherty, a three-times finalist in this event, winning the fourth frame 65-1 was the only bright spot in his clash with Walden.
The Englishman went on to win the final three frames - the final two with impressive breaks of 129 and 128 respectively
Judd Trump, meanwhile, beat Fraser Patrick 6-3 to reach the last 16.
The Englishman 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.
John Higgins produced a vintage showing to beat another former champion Matthew Stevens 6-2.
The Scot made breaks of 59, 81, 62 - after Stevens was first in with 61 in frame four - to lead 3-1 at the interval.
He then added a 128 and a 52 in a convincing win and put his improved form this week down to a new shorter cueing motion.
Shaun Murphy was made to work hard before he finally progressed with the 2008 winner holding off Jack Lisowski towards the end of their tie.
The "Magician", who was the beaten finalist here two years ago, came out on top following a topsy-turvy match against Lisowski, advancing after a 6-4 win.
Murphy lost the first frame but hit back to claim the next four and was unlucky not to claim a century break in the fourth with 98, only to make amends in the fifth with a score of 103-26 to move 4-1 up.
Lisowski pulled one back before 2005 world champion Murphy claimed the next frame and the 23-year-old from Cheltenham attempted to make a comeback as he won the eighth and ninth before his opponent finished the game off with a 67-13 score.
Also on Monday evening, Marco Fu saw off Dechawat Poomjaeng 6-3 to set up a last-16 meeting with Murphy - a rematch of the 2008 final - while Matthew Selt overcame Rory McLeod 6-4 in a late finish.
