Ronnie O'Sullivan crashed out of the World Open in Yushan in the preliminary round after losing 5-3 to Dominic Dale.
World number 94 Dale registered his first career win against five-time world champion O'Sullivan to set up a first-round tie with Dubliner Fergal O'Brien.
Dale opened up a 2-0 lead and, although O'Sullivan pulled it back to 3-3 with breaks of 50 and 91, the 47-year-old from Coventry compiled successive half-century breaks to clinch the next two frames.
Ken Doherty also progressed to a first-round tie with Belfast's Mark Allen after beating Li Yingdong 5-3.
World number one Judd Trump wasted no time in thrashing China's Zhang Jiankang 5-0 to set up a first-round clash with Newcastle's Sam Craigie.
Trump, who led 3-0 after 32 minutes, made successive breaks of 80, 104, 63, 70 and 69.
Mark Selby, recently crowned English Open champion, picked up where he left off with a 5-3 first-round win against Anthony Hamilton, which included a 111 break in the opening frame.
Other first-round winners included Shaun Murphy, Liang Wenbo, Stuart Bingham, Jimmy Robertson, Graeme Dott, Mark Davis, Anthony McGill and David Gilbert.
