Judd Trump’s hopes of a fourth successive world ranking tournament triumph were dashed as he was beaten 6-3 by Scotland’s Stephen Maguire at the International Championship in China.
Trump had won the English Open, Wuhan Open and Northern Ireland Open, beating Maguire in the Belfast quarter-finals.
Maguire led 2-0 and 3-1 as breaks of 56, 69 and 88 helped clinch victory.
Ronnie O’Sullivan progressed to the last 16 as he defeated Jak Jones 6-4, but Mark Allen was among the losers.
A run of 68 in frame two helped O’Sullivan move 2-0 up, and while Welshman Jones cut the deficit with a 77 break, the seven-time world champion edged a tight fourth frame to restore a two-frame margin.
Breaks of 130 and 83 helped Jones level at 44, but O’Sullivan won a scrappy ninth frame before finishing the contest in style with a run of 130.
The 47-year-old will meet Anthony McGill next, after the Scot defeated England’s Jack Lisowski 6-2.
Last season’s player of the year Allen’s disappointing start to the campaign continued as he was beaten 6-3 by Thailand’s Thepchaiya Un-Nooh.
Allen led 1-0 and 3-2 following breaks of 60, 58 and 72, but the Thai, whose only previous ranking tournament triumph came in the 2019 Shootout, produced runs of 60, 72 and a closing 141 to seal victory.
There was better luck for Allen’s compatriot Jordan Brown, who defeated world number eight Kyren Wilson 6-4 to set up a last-16 meeting with John Higgins.
Wilson hit breaks of 106, 93 and 104, but 2021 Welsh Open champion Brown fought back from 3-1 down to clinch victory, aided by runs of 54, 91, 77 and 78.
Higgins beat Dylan Emery 6-1 while Mark Selby, Ali Carter, Barry Hawkins and home hero Ding Junhui were among other players to reach the last 16 in Tianjin.
