Four-time world champion John Higgins is through to the second round of the Northern Ireland Open at the Waterfront Hall.
The World No.5 defeated China's Chang Bingyu 4-2 in the first round clash in Belfast, which sets up a second round tie with either Riley Parsons or Kacper Filipiak.
Meanwhile, former World No.1 Mark Selby has also reached the second round after his 4-2 win over Xu Si earlier in the day.
The three-time world champion made light work of his Chinese opponent and will now face Matthew Stevens in the next round, after the Englishman defeated Chris Wakelin in his first round tie.
And it was an easy night for Shaun Murphy, who romped past Fraser Patrick with a 4-0 win to set up a second round meeting against either Dominic Dale or Luo Honghao.
There have been some early casualties in Belfast, however, with World No.10 David Gilbert and World No.16 Ding Junhui the two biggest shock eliminations on day one of the tournament.
Gilbert was knocked out after a mammoth final frame against Anthony Hamilton, beaten 4-3, while 13-time tour winner Ding was eliminated by England's David Lilley, losing 4-2 in the afternoon session at the Waterfront Hall.
There were further shocks in Belfast as Ryan Day, Xiao Guodong and Lyu Haotian all fell at the first hurdle as well, with Day defeated 4-1 by Harvey Chandler, Guodong beaten 4-2 by Alexander Ursenbacher, while Haotian lost 4-1 to fellow countryman Tian Pengfei.
Further upsets saw Tom Ford and Hossein Vafaei both whitewashed 4-0 in their first round clashes with Andrew Higginson and Si Jiahui respectively, while Anthony McGill was knocked out by Robbie Williams, 4-1.
And Irishman Ken Doherty was spurred on by the local support at the Waterfront to shock Michael Georgiou, winning 4-2 in the headline game of the midday session.
There were no such worries for other big names such as Stephen Maguire, who recorded a 4-0 whitewash of Declan Lavery, or Ali Carter, who defeated Robert Milkins 4-1, while Yan Bingtao had to battle to see off Andy Hicks 4-2.
Elsewhere, there was joy for Northern Ireland's Jordan Brown, who reached the second round with a 4-2 win over James Wattana, but it was disappointment for Gerard Greene as he was defeated 4-1 by former Grand Prix champion Marco Fu.
In the day's final match, 15-year-old Robbie McGuigan, the step-son of Antrim's Mark Allen, was whitewashed 4-0 by fellow Northern Irishman Patrick Wallace.
