UK Championship 2013: Shane Castle cool on Mark Selby clash

Teenager Shane Castle refuses to let the enormity of facing world number two Mark Selby on his UK Championship debut overawe him.

The 15-year-old, who is one of seven amateurs lining up against the professionals in the first round after a competition revamp, takes on the defending champion on Saturday.

"I'll try to treat it like a normal amateur match, but I'm looking forward to it," Castle told BBC South Today.

"Nerves have never really bothered me."

The seven amateurs

Shane Castle: 15 years old, from Southampton. Plays Mark Selby

Rhys Clark: 19, Stonehouse, South Lanarkshire. Plays Ronnie O'Sullivan

Dylan Mitchell: 18, Bradford. Plays Neil Robertson

Antony Parsons: 35, Middlesbrough. Plays Ding Junhui

Sanderson Lam: 20, Leeds. Plays Stephen Maguire

Mitchell Travis: 20, Sheffield. Plays Marco Fu

Gareth Green: 23, Bradford. Plays Judd Trump

Castle admits there is no escaping the awe of Selby, who sent an ominous warning ahead of his title defence by proclaiming that he is feeling at the top of his game after beating world champion Ronnie O'Sullivan in the final of the Antwerp Open earlier this month.

"I'll be up against a lot I suppose," Castle said.

"I know I can't really miss any balls against him, otherwise it is frame over."

That was a lesson that China's Ding Junhui delivered to Castle in devastating fashion at the International Championship in Chengdu earlier this month, claiming a 6-0 win in the round of 128 on the way to the title.

"It was a big experience," Castle said.

For prodigious potter Castle, however, taking on Selby at the Barbican Centre it is just another step in his meteoric rise.

He first picked up a cue at the age of seven, was competing regularly a year later and dominating junior snooker from age nine. Castle has since gone to win multiple junior English championships and narrowly missed out on becoming the youngest ever European Under-21 champion in 2012.

With his parents having supported his early desire to turn professional soon by allowing him to leave school, Castle is in a hurry to make his name in the sport.

When he starts talking about wanting to turn professional at 16, the parallels with five-time world champion O'Sullivan, who did the same in 1992, are clear.

The Southampton youngster does not want the comparison to simply stop there either.

"I want to be world champion - that's the dream," Castle said.

"I've got a lot time ahead of me and I want to get on the [professional] tour by 16 and play in all tournaments instead of just getting picked for one."
