O'Sullivan edges past Williams

Ronnie O’Sullivan resisted a doughty challenge from Mark Williams to edge through 13-11 in their 888.com World Championship quarter-final at Sheffield’s Crucible Theatre tonight.

‘The Rocket’ clinched a repeat of the 2004 final against Graeme Dott, while the other last-four clash will feature 2002 champion Peter Ebdon against surprise package Marco Fu.
