Mark Allen is through to the quarter-finals of the International Open in Chengdu, China after beating England's Stuart Bingham 6-4 on Wednesday.
The Antrim player will face Welshman Michael White in the last eight of the ranking event.
Belfast's Joe Swail bowed out at the third round stage however, losing 6-4 to Ricky Walden.
The Northern Irishman had caused a major upset in the previous round by beating Australian Neil Robertson 6-5.
Swail, ranked 71 in the world, came from 5-3 down to defeat the former world champion on Tuesday.
The 45-year-old, who has reached just one ranking final in his career, was unable to repeat his heroics against Englishman Walden.
World number two Robertson, who became the eighth player in snooker history to win the Triple Crown when he added the UK Championship to his Masters and World Championship victories last December, opened with a break of 101 against Swail on Tuesday.
He rattled off the next two frames for a 3-0 lead before Swail, who lost his professional status in 2012 before improving his form and regaining it last year, got on the board with a break of 81.
The next four frames were shared, with Robertson compiling a break of 106 to move within a frame of victory.
But Swail edged a tight ninth frame and then won the last two to set up his third-round meeting with Walden.
