Ronnie O’Sullivan is not used to missing balls on a snooker table.
So it’s little surprise that a miss in the Northern Ireland Open left him riled up, headbutting the table in frustration after watching a simple black not drop.
The faux pas didn’t cost him however, still overcoming Zhou Yuelong 4-1 in the fourth round.
He then went on to beat David Gilbert 5-2 and now a semi-final against Mark Selby awaits, in what is set to be a thrilling contest in Belfast.
