Stephen Maguire was rocked by one of the biggest upsets in snooker history last night as he lost 10-9 to rank outsider Dechawat Poomjaeng in the first round of the Betfair World Championship.
Scottish potter Maguire reached the semi-finals at the Crucible last season but was shaken up by world number 70 Poomjaeng, who only joined the main professional tour last season and whose antics endeared him to the crowd but seemingly not to Maguire.
The Thailand player laughed and smiled along with spectators and repeatedly apologised when the run of the ball favoured him, but Maguire rarely saw the funny side as he endured perhaps the worst defeat of his career.
Like Graeme Dott's match against Peter Ebdon, it went beyond the scheduled two sessions, largely due to Poomjaeng's meticulous and slow play on his World Championship debut.
Meanwhile, Ali Carter set up another clash with his Crucible nemesis Ronnie O'Sullivan by finishing off Ben Woollaston.
Carter and O'Sullivan have gone head to head three times in Sheffield: in the second round eight years ago and then in the finals of 2008 and 2012.
Each time O'Sullivan has come out on top, and in their 12 previous meetings at major tournaments Carter has lost the lot, suggesting he will be up against it when he tackles the defending champion.
Carter had trailed 3-1 at one stage against Woollaston but recovered to lead 5-4, and he made the World Championship newcomer suffer in his seat last night, starting with a break of 106 and rattling off the five frames he required without reply, winning the match 10-4.
Elsewhere, Judd Trump leads Dominic Dale 6-3 lead after firing in breaks of 88, 142 and 82, and he should have been further ahead at the end of the session, wasting a clear chance in the ninth frame.
Ding Junhui set himself on course for the last 16 as leads Alan McManus 7-2.
