Mark Williams cruised past Alan McManus last night by winning six frames on the spin and winning 10-5.
The three-time world champion had trailed overnight but won all six frames played in the evening session to beat the veteran McManus.
Another former world champion also booked his place in the second round as Stuart Bingham beat Ashley Carty 10-7.
The 2015 world champion, Bingham will now face Williams in the second round.
So far none of the qualifiers have managed to cause an upset against the top seeds, however Mark King came very close to dethroning world number 11 Ding Junhui, forcing a final frame decider
Ding came out on top eventually in a tight frame, winning the decider on the blue ball.
The other matches of the day saw Kurt Maflin take a 5-4 lead over 2019 semi finalist David Gilbert, whilst four time world champion John Higgins leads Wales’ Matthew Stevens 6-3.
The World Championship continues today and five time world champion Ronnie O’Sullivan will be facing Thailand’s Thepchaiya Un-Nooh.
O’Sullivan has not had the best record at The Crucible in recent years, particularly with a shock loss against amateur James Cahill last year.
Thepchaiya Un-Nooh will certainly be a match for The Rocket. He has the lowest shot time of any player in the game, making him the fastest player on the tour. The man from Thailand averages 14 seconds per shot.
World number two Neil Robertson will also begin his campaign for a second world title against Liang Wenbo.
The match-up is a repeat of the 2015 UK Championship final, which 2010 world champion Robertson won 10-5.
20 year old Yan Bingtao will also be playing Gateshead’s Elliot Slessor in only his second Crucible appearance, and first since 2017 when he was just 17 years old.
The young Chinese player qualified automatically after an impressive season which saw him enter the top 16 in the world.
