O'Sullivan makes mark on Williams

Ronnie O’Sullivan should today reap reward for the scintillating session of snooker which carried him to the brink of another Crucible victory over Mark Williams.

Three-time champion O’Sullivan, 36, fired two centuries and four further hefty breaks in converting a 5-3 cushion into an 11-5 lead. His runs were of 107, 74, 51, 68, 128 and 93 and he needs two more frames this evening to reach the quarter-finals.
