World champion Mark Selby eased to a 6-0 victory over amateur Oliver Brown to reach the last 64 of the UK Championship in York.
The Jester from Leicester was not in sparkling form but rounded off the match with a break of 124 to book a second round meeting with David Morris, who overcame Li Hang 6-4 late on Wednesday evening.
John Higgins, a three-time former champion, also moved through comfortably winning 6-2 over Lee Walker, to set up a clash with Jamie Cope, who defeated John Astley by the same scoreline.
Veteran Steve Davis briefly challenged world number eight Ricky Walden, sharing the first four frames of the contest, but Walden pulled clear from thereon, running off four in a row to win 6-2. Walden will face Robbie Williams in the next round, after the Englishman secured a 6-4 victory over Sam Baird.
DING STORMS THROUGH
Chinese number one Ding Junhui moved effortlessly through to the last 64 with a 6-0 drubbing of Irish amateur John Sutton.
The two-time former champion was not in sparkling with only three breaks above 50, but was rarely tested by his inexperienced opponent, who threatened only in the fifth frame. Ding will play six-time world finalist Jimmy White in round two, who defeated Stoke's Dave Harold 6-2, the highlight being a break of 110 in frame six.
Mark King suffered a shock 6-0 loss to 18-year-old James Cahill. The youngster's reward is a second round bout against Andrew Higginson who knocked out Tian Pengfei 6-3.
Tony Drago sprung a surprise 6-4 triumph over Dominic Dale. The Maltese speedster struck a break of 109 in the fourth frame in an impressive performance. Drago's last 64 opponent will be Ben Woolaston who beat Gloucester's Michael Wasley, also 6-4.
Matthew Stevens, champion 11 years ago, hit a 132 break on his way to a 6-2 win over Allan Taylor. The Welshman will meet Gerard Greene next after the latter also recorded a 6-2 victory, against Australian Vinnie Calabrese.
Brazil's Igor Figueiredo is also through to the second round after seeing off Ireland's Fergal O'Brien 6-4. Anthony McGill will be Figueredo's next challenge, after the Scot edged past Michael Georgiou by the same margin.
