Joe O’Connor missed out on a maximum but chiselled a 5-4 advantage over John Higgins after the opening session of their World Snooker Championship first-round clash that is due to conclude on Monday evening.
The Leicester qualifier potted 12 reds and red blacks in the seventh frame and was on track to make the 15th 147 in Crucible history before missing a tough red to the top corner with the rest.
