BBC Sport at the Crucible
Mark Williams is in fine form
Former champion Mark Williams was in unstoppable form as he blitzed Quinten Hann 13-2 to reach the quarter-finals.
The Australian began the session trailing 6-2, but he found the Welshman in unforgiving mood.
The world number two played flawless snooker, stifling the 14th seed, and rattling off the first seven frames to seal a remarkable 13-2 win.
It meant Williams had won a record 13 frames in a row to book a quarter-final spot against Stephen Hendry.
He admitted he was surprised at the ease of his win.
"We both struggled for the first four or five frames, but after that I was in control of the match," said Williams.
"It's unbelievable to win 13-2 at The Crucible, especially against a player who can play as well as Quinten.
"I'm looking forward to playing Stephen. I'm aiming to get back to number one in the world and it should be a good game."
Hann said he felt he had let himself down.
"I just think I played badly for the whole match. I got to 30 quite often, but couldn't get any further," said the Australian.
"I had plenty of chances, but to be truthful I was going to get beaten by whover I was playing today.
"I don't know why I played so badly, I just did. I've been practising lots lately, so maybe it's time for a rest."
