Judd Trump has reached the China Championship last 32 after a comfortable 5-0 victory over Mike Dunn on Tuesday.
The world champion took control of the contest after winning a couple of early scrappy frames.
A 122 helped Trump to cushion his advantage before the world number one eased to winning line.
The 30 year-old, who triumphed in the last ranking event this season in China when he overcame Shaun Murphy in the final of the International Championship last month, will next play Zhou Yuelong.
The latter beat Thepchaiya Un-Nooh 5-1 while Murphy maintained his excellent form of late with a 5-3 triumph against teenager Yuan Sijun.
Meanwhile, the biggest upset of the day was fashioned by Zhao Xintong, who prevailed with a 5-3 scoreline against fellow Chinese competitor Ding Junhui.
In a cagey affair, Ding marginally scored heavier but couldn’t see off frames as his 22 year-old compatriot crucially pinched three on the black.
While it represents one of Zhao’s career-best victories, for Ding it’s another bad defeat to add to the list as a prolonged period of poor form shows no signs of a let-up.
Kyren Wilson boasted arguably the performance of the day when he fired in a brace of tons and two additional breaks above 50 to hammer Robbie Williams 5-0.
By contrast, 2017 winner Luca Brecel was taken the distance before surviving a tough encounter with Tian Pengfei in a decider.
Tian led 4-2 but the Belgian fought back with breaks of 89 and 73 before pinching a dramatic final frame on the colours.
Brecel has struggled for consistent form since his maiden success two years ago and is provisionally set to plummet outside the world’s top 16 after the conclusion of this tournament unless he has a strong week in Guangzhou.
Elsewhere, there were routine wins against home opposition for reigning champion Mark Selby and Neil Robertson, while David Gilbert thrashed Marco Fu 5-1.
Mark Allen progressed to the China Championship last 32 as well, firing in a tournament-high 145 total clearance in ousting Anthony Hamilton 5-3.
Former ranking event winners Stephen Maguire, Anthony McGill, and Joe Perry survived another day in the third ranking event of the campaign, which boasts a top prize of £150,000.
There were comprehensive 5-1 victories for Jack Lisowski and Hossein Vafaei, two players who could make a bid for a first success at this level in the coming days.
Luo Honghao was the other player to win on day two, edging former top 16 member Ricky Walden 5-4 to set up a clash against Mark Williams
