14:30

Ronnie O'Sullivan 5-4 Ali Carter

Luca Brecel v Ryan Day

19:00

Judd Trump 6-3 Zhou Yuelong

Judd will be fairly happy. He was not at his brilliant best. Pot success was 90%, to win this Championship you'll need to go up to 94 or 95%.

He had chances to have a bigger lead but the first round is just about getting through it. I think he'll be happy with his night's work.

All credit to Zhou Yuelong for the red he potted at the beginning of the last frame...if it doesn't go in it is 7-2.

Zhou Yuelong ends the session with a break of 95.

Sometimes you have to take the bull by the horns and force the issue. Zhou is not going to win this match with breaks of 30.

He has won the frame at one visit, it is a good end to the session and he has given Judd something to think about overnight.

Zhou Yuelong eclipses his highest break of the night which was 52 in the third frame.

He is at 60 and counting.

England's David Gilbert has just given a brutally honest assessment of his performance during his 10-6 loss to China's Si Jiahui.

"I don't think it could've gone any worse," said Gilbert in his post-match news conference.

"I thought Si was very poor and I was very poor, but to be down 6-3 and 9-4 was unbelievable. I played poor so I deserved it. I lost the match yesterday.

"I couldn't pot a ball and my mid-range game was nowhere and it made it easy for him. I had felt great and was really looking forward to coming here. I love the Crucible. It's a great place but it's not very nice when your game is not there.

"I thought if I had got it to 9-7 he would've collapsed as he looked edgy. He will have to play a lot better than that."

On missing a potential 147 in the second frame of the evening when he faltered at 72, he added: "From ball one I was chasing the cash. I was fuming that I missed the red into the middle."

If Judd Trump does end up facing Shaun Murphy, he will feel pretty confident. He has won their previous seven meetings.

The most recent of those was a 6-0 triumph in the quarter-finals of the Players Championship in March.

Still, he has work to do here first. Zhou Yuelong is at the table looking to get a third frame on the board.

Just like Shaun Murphy earlier on today, Judd Trump is putting himself in a great position to wrap up his first-round match tomorrow.

However, if they both win as expected, it will get harder for both of them - as they would play each other in what could be the standout tie of the last-16 matches.

Both are trophy winners here, Murphy 20 years ago and Trump in 2019. It would be the current Masters champion (Murphy) against the world number one and UK champion (Trump).

Two of the three sessions would take place on Sunday, with the final instalment on Monday afternoon.

That is a wild thrash at the yellow from Zhou Yuelong. But he gets away with it initially.

Judd Trump now misses a long pot but when he's allowed a look at a thin cut he flicks it in.

The green and brown follow and that's the frame.

Zhou Yuelong lays a good snooker on the final red to give himself a chance when his opponent nudges towards the top right corner.

But he can't get position on the yellow, which is lodged the wrong side of the left middle as far as he is concerned.

Judd Trump races up to Zhou Yuelong's 30-point lead and goes past it with ease.

But he looks mortified when he overcuts a red to the left corner.

As per the story of this match, his opponent doesn't punish him and the frame is still in the balance.

Dave Gilbert made a spirited comeback but his World Championship is over.

Si Jiahui seals a 10-6 victory and will play four-time world champion Mark Selby or Ben Woollaston in round two.

Zhou Yuelong is finding his rhythm now or was...a yellow with the rest rattled in the top left corner pocket and at break of 30 feels likes a meagre reward for several excellent pots.

Too many of those simply have not dropped for Zhou Yuelong. The 27-year-old from China leaves a red dangling over the pocket and it gives Judd Trump the chance to get back ahead in the frame.

However, he gets another chance and when the world number one leaves a chance on the brown, Zhou is able to collect his second frame of the match.

At around 44 minutes that's the longest frame of the match and one for the purists.

Zhou Yuelong is currently on a break of 29. Which given the state of the table feels like a 60.

He misses a red to right middle though and tees up Judd Trump, to make a break of at least six.

You wait 14 frames for a century and then two come along at once.

Dave Gilbert has looked revitalised since the interval, strolling round the table, smoothly knocking in the pots.

He strokes in 102 to pull the deficit back to 9-6.

It would be fair to say the seventh frame is a scrappy attritional affair.

There are currently four reds down on the bottom cushion. There were seven a couple of minutes back.

Sorry make that five.

It took until the 14th frame, but what a time for Dave Gilbert to get the first century of this match.

The Englishman knocks in 104 in the first frame after the restart, but he still needs five more on the trot to stay in the tournament.

Judd could win this session 8-1 and then the match is over. I think he would be disappointed if this ended up 7-2.

The pre-tournament favourite with the bookmakers, Judd Trump, goes 5-1 up with a break of 62. It is all looking very easy for him at the moment.
