Thepchaiya Un-Nooh suffered the agony of a missed black which would have wrapped up a maximum break at the Betway UK Championship on Tuesday night.
Un-Nooh would have scooped a £44,000 windfall if he'd potted a relatively straightforward final black in the sixth frame of his last-32 match against Neil Robertson at the York Barbican, but he rattled the jaws of the pocket.
It was cruel on the 30-year-old Thai, as he had expertly crafted a break of 140 only to fall at the final hurdle. It would have been his first official maximum.
He was trailing the Australian 4-1 at the time of his close call and he never seemed to recover from the dramatic near miss.
Robertson clocked up a brilliant 145 in the next frame to lead 5-2 and create a new target for the £4,000 high break prize, en route to a 6-2 victory and a place in the last 16.
Judd Trump squandered a 4-1 lead to suffer a shock defeat to Liang Wenbo. The Englishman was seemingly in complete control, but lost five frames in a row to make his exit.
Hong Kong’s Marco Fu will meet Shaun Murphy in the last 16 after he eased past David Gilbert 6-3, while Un-Nooh's compatriot Dechawat Poomjaeng edged past Mark Joyce 6-5.
