Ronnie O’Sullivan is a frame away from reaching the World Snooker Championship quarter-finals

Ronnie O’Sullivan is through to the semi-finals of the World Snooker Championship for a 14th time, holding his nerve to defeat China’s Si Jiahui 13-9 in Sheffield.
O’Sullivan will face another Chinese player in Zhao Xintong – who is competing under amateur status – for a place in the final, with the latter defeating England’s Chris Wakelin 13-5 in their quarter-final.
After struggling earlier in the session, Ronnie O’Sullivan finds some scintillating snooker to finish off Si Jiahui 13-9.
He extended his overnight advantage to 7-2 when he took the opening frame of the morning, capitalising after Si had missed a straightforward pink off the spot.
Si, a semi-finalist on his Crucible debut two years ago, then crafted a break of 101 before a fluked cannon red into the bottom corner helped set O’Sullivan on his way to a run of 75 to take the 11th frame in one visit.
Si reduced the deficit again heading into the mid-session interval, but O’Sullivan pinched the first frame back after his opponent missed a frame-ball red, getting a couple of snookers before clearing the colours.
