Defending champion Judd Trump cruised into the last 32 of the BetVictor Northern Ireland Open with a 4-0 victory over Gao Yang, who failed to register a single point.
Trump is seeking to make it four titles in a row in Belfast and this 23rd consecutive win at the event was achieved with 333 unanswered points.
"He let me in quite easily in the first couple of frames. I know the top players aren't going do that," he told wst.tv after breaks of 54, 100, 60 and 52.
"It is still pleasing to score like I did and put pressure on him early on. I made a couple of good breaks and all-around my game was pretty good there.
"It was a bit of a stepping stone for the next round."
Shaun Murphy, runner up in this year's world championship, was pushed all the way by world number 75 Allan Taylor before closing out a 4-3 victory
Jack Lisowski saw off Fan Zhengyi 4-2, the same score registered by Northern Ireland's number one Mark Allen against Peter Devlin, while there were also wins for David Gilbert, Neil Robertson, Stuart Bingham and Jimmy Robertson.
