Ronnie O'Sullivan against Si Jiahui Live: Results and scores from the World Snooker Championship

“I only drag it out. I had done my work on my keyword today. I play terrible and the keyword feels terrible, so it's the worst situation, but I'm still in there, so I will continue to try. He had many opportunities and tried to keep the keyword in different places just to get a different feeling.

“Si played really bad throughout the game. I was lucky again. I am looking forward to the semi -finals, every match is an opportunity. I love playing the Chinese players well – they are so nice boys and it's not easy. I still think that there are charges that can improve Zhao.”

Next it will be Zhao Xintong for Ronnie O'Sullivan – it will be a harder test, but there was a real steel in these last frames of the seven -time world champion.

Far away from perfect from Ronnie O'Sullivan, but he is in the last four! Si Jiahui gave him the chance to seal it in the last two frames and the rocket powers.

Si flops on the table – a miserable shot that stretched out after the brown and does not find the bag. Yuck. He had his chances.

Si Jiahui lets Si Jiahui in the middle with a simple starter. He has to let this count.

After he has already extended his stay in Sheffield, Judd Trump is – here is how he sealed him after a dominant five frames against Luca Brecel. The Belgian sometimes really seemed to take control of the game this afternoon, but Trump only looks stronger and stronger.

No mistake this time! A delightful red to get going again for Ronnie O'Sullivan, and he also knocks on with serenity. Release is required … and reached. It is a frame of the last four.

Si comes close to a different coincidence, although the red does not increase in the yellow bag. For Ronnie O'Sullivan an opportunity for Ronnie O'Sullivan, two red under the brown (which occupies the black spot) is the most likely that he troubles.

He leaves her sensibly until the end. And miss the first of them! Gah. He gets away with it, but still at 25.

Five frames, five won and won the semi -finals – sparkling things from Judd Trump, starting with a few centuries and never look back tonight. Luca Brecel is sent 13-8 in quick time.

However, a missed pot arrives relatively quickly. Back to a battle for security -until Si Jiahui is lucky with an accidental two -ball fluke.

He moves quickly to 49 before a table strike reveals his frustration that he no longer had the position. Can he fire along the lower pillow in a hard red? No, but he played it skillfully to get up again. Encourage signs that Si Jiahui begins to believe that he can win this.
