Jamie Jones suffered a shock 6-0 first-round defeat to Gary Wilson as the UK Championship got underway with a series of upsets in York.

Jones, from Neath, burst onto the scene at the 2012 World Championship with a run to the quarter-finals and would have expected to brush aside the world number 91, whose short-term goal is simply to make enough money to give up his job as a taxi driver.

But Wilson, who enjoyed success in last season's Players Tour Championship and has reached a semi-final in Rotterdam and the last 16 in India this season, barely gave the Welshman a sniff as he charged to a 6-0 win.

The Wallsend cueman said on World Snooker's official YouTube channel: "I've had a few good results but that's probably the best I've played this season. I was solid throughout, I didn't give too much away."

The world's top 128 will all be in first-round action over the coming days and Wilson said: "I like the structure, I like the way it's given everyone a fair chance in round one.

"I think it's the way forward for every tournament."

Wilson was sporting an impressive 'Movember' moustache but said: "That'll be gone in December, don't worry!

"I was thinking if I get through and it comes to December, I'll have to keep it on. I'll jinx it if I shave it off, maybe.

"But it looks horrendous, let's be fair - it's going to have to come off."

Teenager Sean O'Sullivan amazingly came from 4-0 down to beat two-time ranking event finalist Anthony Hamilton 6-4.

O'Sullivan got the snooker he required in frame 10 and a free ball to boot as he cleared from the final red to take frame and match.

Australian Vinnie Calabrese also claimed a notable scalp, edging out Dominic Dale in a final-frame decider.

Calabrese, who earned his place on the main tour by winning this year's Oceania Championship, led 5-3 but Dale took a tense ninth frame to keep the match alive and made a 101 break to level matters.

With black and pink locked together, the final frame became a messy safety exchange but Calabrese produced a match-winning 70, with a superb opening red and a well-judged cannon from the black to the decisive red.

Tom Ford was beaten 6-2 by Thailand's world number 110 Noppon Saengkham in the other game of the afternoon session as all four were won by the player outside the top 64.

In the evening session, world number 95 Jamie O'Neill bridged a 57-place ranking gap to beat Mark Joyce 6-2 in a fluent display featuring breaks of 66, 110, 85 and 89.

But Xiao Guodong and Mark King managed to buck the trend with 6-1 wins over Andrew Pagett and Ross Muir respectively.

Xiao led 3-1, with breaks of 56, 72, and 57, as the interval came around in quick time.

And there was no let-up as he wrapped up victory, a 125 break in frame seven putting the seal on a performance even more polished than Xiao's silver mirror-shine shoes.

King also advanced to the second round after an equally comfortable, if significantly longer, match against Muir while Ireland's Fergal O'Brien was a 6-2 winner against Alex Davies.
