Ronnie O'Sullivan suffered a shock second round exit at the China Open after losing a final-frame decider to world number 51 Mark Joyce.
Despite producing two century breaks, the five-time world champion never led in the match and was eventually knocked out 5-4 as Joyce set up a last-16 meeting with home favourite Ding Junhui.
Joyce made a 137 clearance in the seventh frame to move 4-3 ahead after O'Sullivan shot a break of 132, but the Rocket came back to level at four apiece to set up a decider, which Joyce then took with 62 points to 34.
Chinese player Ding progressed in emphatic style, hitting successive centuries of 109 and 127 in the opening two frames on his way to a 5-0 whitewash of compatriot Zhou Yuelong.
O'Sullivan was not the only big-name casualty of the second round as two-time World Championship finalist Ali Carter surrendered a 3-2 advantage to lose 5-3 against world number 28 Michael White.
World champion Mark Selby ensured his place in round three in routine fashion, seeing off Martin O'Donnell 5-1, while last year's winner Judd Trump continued his title defence with a 5-0 victory over Scotland's Eden Sharav.
John Higgins will face fellow former world champion Mark Williams in the third round after ending his hoodoo against Mark Davis.
The veteran Scot, who lost all four of his previous meetings with Davis, triumphed 5-2, while Welshman Williams came from a frame down to beat Michael Holt by the same scoreline.
