Hossein Vafaei upsets Selby to progress at the UK Championship

Two-time champion Mark Selby crashed out of the UK Championship after a 6-4 defeat to Iran's Hossein Vafaei in York.

Selby, the winner of the tournament in 2012 and 2016, struggled to find his rhythm throughout and missed a chance to force a decider when he left Vafaei a cut to the middle in the 10th frame.

The 28-year-old Vafaei, who reached a career-best fourth round last year, held his nerve to sink a difficult green and brown and claim one of his most significant wins.

Defeat continued an underwhelming campaign for Selby, the seventh seed to lose in the tournament, whose best result remains his semi-final appearance in the Champion of Champions tournament earlier this month.

Vafaei's reward is a last-16 clash with Jack Lisowski, who fired breaks of 73, 83 and 66 as he cruised to a 6-1 win over another Chinese player, Xu Si.

Earlier on Tuesday, Judd Trump overcame his "atrocious" UK Championship record to edge China's Xiao Guodong in a final-frame decider and also book his place in the last 16.

Shaun Murphy came through a high-quality contest against David Gilbert, forcing a decider with a break of 133 before dominating that final frame to advance.
