Mark Allen set up a last 16 tie with Joe Perry in the International Championship after victory over Dave Harold.
However the big news from Chengdu was the early exit of five-time world champion Ronnie O’Sullivan at the hands of Liang Wenbo who recovered from three frames down to progress.
O’Sullivan, who had not played in a major tournament since winning the World Championship at the Crucible in May, made a successful return to ranking event action by beating Anthony McGill in the first round in China on Monday.
The Essex potter built a 4-1 lead against Liang, but could not progress to a knockout meeting with Mark Davis - a 6-3 winner over Stuart Carrington - as his 26-year-old opponent won five straight frames to clinch a shock 6-4 victory.
Last year’s runner-up Neil Robertson is safely through to meet Peter Ebdon, who edged Mark Joyce 6-5, after he dispatched Thepchaiya Un-Nooh 6-1.
There was, however, disappointment for Barry Hawkins as he lost to Zhao Xintong.
