The World Snooker Championship rolls on with the action at the Crucible Theatre in Sheffield heating up as the tournament reaches the semi-final stage.

A number of top contenders have already fallen, including defending champion Kyren Wilson - pipped by Lei Peifan in the first round - and four-time winner Mark Selby, who was knocked out by training partner Ben Woollaston.

There have been no such problems so far, though, for a returning Ronnie O’Sullivan. The seven-time champion made a mockery of his recent period of inactivity, beating Ali Carter, Pang Junxu and Si Jiahui before a semi-final contest with Zhao Xintong.

The 49-year-old O’Sullivan decided to play at the Crucible despite admitting he was “scared to go near a snooker table” during his break from the game and feared he had lost his bottle.

The World Snooker Championship got underway on Saturday 19 April with the final played over two days starting on Sunday 4 May.
