Former champion Shaun Murphy crashed out of the first round of the UK Championship with a 6-5 defeat to Chinese amateur Si Jiahui in York.

Murphy – winner of the tournament in 2008 and runner-up at the World Championship earlier this year – fought back to force a decider against the 19-year-old, who fell off the main tour at the end of last season, but then spurned an opportunity to finally put the match to bed.

Si had earlier missed a golden chance himself to wrap up what would have been a comfortable 6-1 win after clawing back three snookers required only to then miss the blue with victory seemingly in sight.

Murphy, world champion in 2005, continued his momentum to mount a fine recovery with breaks of 60, 87 and 85 to fight back and level the match at 5-5.

The deciding frame saw a re-rack before Si produced a half-century break only to allow Murphy back to the table, who showed his experience to build a run of 44 and put pressure back on the Chinese teenager.

Si then left the final two reds open, and Murphy sank a long pot – only to then inexplicably miss the blue which handed the teenager an unexpected opportunity to finally wrap up a memorable victory just before midnight.

Earlier, three-time UK champion John Higgins fired two centuries in the final three frames to wrap up a 6-1 win over Michael Georgiou.

Former world finalist Kyren Wilson fired a break of 110 as he joined Higgins in the second round with a 6-2 win over Soheil Vahedi.

Today, Cork's Aaron Hill is in first round action against Noppon Saengkham.
