Last year's losing finalist Matthew Stevens booked his place in the second round of the world snooker championship with a comfortable 10-5 win over Ulsterman Joe Swail.

Swail was critical of the playing conditions following a series of 'kicks' during the match.

"I was disgusted with the table because it was an absolute joke," said Swail.   

World number one Ronnie O'Sullivan dominated the first session of his match against Dave Harold, compiling breaks of 139 and 106 on his way to establishing a 7-0 lead.

Harold won the last two frames of the session to avoid an embarrassing whitewash, cutting O'Sullivan's advantage to 7-2.
