Ding Junhui held his nerve to knock out five-time champion Ronnie O’Sullivan in the World Snooker Championship 2017 at The Crucible. In a classic quarter final match Ding edged to a 13-10 win despite a strong start from O’Sullivan including a magnificent 146 break. It is Ding’s first ranking-event win against O’Sullivan since 2006. Sheffield Live! reporter Azz Mohammed was at The Crucible.
