Snooker: Out-of-sorts Williams edges through

World champion Mark Williams survived a close shave in the first round of the Regal Welsh Open in Cardiff and admitted: "My head's in a bucket at the moment".

The 25 year-old left-hander holds a virtually insurmountable lead at the head of the provisional world rankings and has not lost his opening match in a ranking event since the Regal Scottish Open in February last year.
