Michael White caused the first major shock of the Betfair World Championship as the debutant from Neath knocked out Welsh compatriot Mark Williams to launch his Crucible career.

Two-time former champion Williams made a similar impact in his first match at the World Championship 16 years ago, when he beat Terry Griffiths.

That proved to be Griffiths' final match at the Crucible, and three years later Williams landed his first title in Sheffield.

Qualifier White, only 21, could prove to be the next in the line of great champions Wales has produced, and he was well worth his 10-6 margin of victory on Sunday.

"He played really well and deserved to win. He must have a great future and should be able to earn a lot of money" - Mark Williams

He came into the match speaking highly of Williams, but there was no deference to the 38-year-old once they began the match.

White began the match with a break of 87 and settled the issue by firing in a 96 before being warmly congratulated by Williams.

There was no doubt White looked the part, and the youngster now has a new place in snooker history, having already earned an entry in the Guinness Book of Records by making a century break in a league match at the age of nine.

Williams was charitable with praise for his conqueror, saying: "He probably outplayed me in every department.

"Overall you can't argue with that. Talk about the young players coming through and he's one of the best of them.

"People keep mentioning Jack Lisowski and people like him. He's up with them, if not better.

"He's still only 21 and playing like that he's dangerous for anybody. You wouldn't have thought that was his first time out there.

"He played really well and deserved to win. He must have a great future and should be able to earn a lot of money. He's on the right track and best of luck to him."

The 2005 champion Shaun Murphy made a solid start, beating Martin Gould 10-5.

A tense 57-minute 10th frame proved pivotal, with Murphy taking it to lead 6-4 rather than giving Gould hope at 5-5.

Sale-based Murphy pulled clear from there, and a break of 106 in the 14th frame took him one away.

He was on for a maximum break after taking eight reds and blacks at the start of the final frame but took pink off the ninth red after running slightly out of position and eventually settled for 95.

He faces Dott or Ebdon next.

Murphy said: "It was very pleasing to see the hard work I put in for this tournament came out when I needed it."

Gould said: "He can definitely go all the way. We'll have to see."
