Despite not having played competitively in three months and returning with an untried cue, Ronnie O'Sullivan is through to yet another semi-final, seeing off Si Jiahui 13-9.
By the time the youngster began to believe he could win, the lead was too great and, as he has throughout the tournament, O'Sullivan found something every time he needed it. He will, though, need to go up several levels to beat Zhao Xintong.
Wednesday's other match looked set to be a classic, Judd Trump and Luca Brecel beginning the session locked at 8-8. But Trump made centuries in the first two frames – his 103rd and 104th of the season, a new record – and maintained his high level to win the next three.
His last-four opponent is Mark Williams who, earlier in the day, beat John Higgins
in a final-frame decider.

Ronnie O'Sullivan beats Si Jiahui 13-9
He'd not played for three months and also changed his cue; that's how good he is. He meets Zhao Xintong next, while Si will feel he could've done better.
O'Sullivan 12-9 Si (63-43)
Ronnie makes it safe and can it be tomorrow already please?
O'Sullivan 12-9 Si (54-43)
There are two reds under the pink; they're the only impediment to Ronnie reaching yet another Crucible semi. Even at 60%, he's still nails to beat. And, as I type, he gently moves off black on to the aforementioned pair of reds; "Delightful, there's never been a player who sees a shot as early as Ronnie," rhapsodises Fouldsy. This is over.
O'Sullivan 12-9 Si (17-43)
Si stretches across the table to slot a yellow ... and flops on to it when the ball stays out! He knows this could be curtains, and it'd be typical of how Ronnie is at the moment were he to put the match away.
O'Sullivan 12-9 Si (0-42)
Si hasa lot of talent, but looks a very similar player to the one that lost to Luca Brecel in the 2023 semi, in amazing fashion; he's a blazing potter but not loads else, so needs to be playing well to win matches. However, he's taking these balls very nicely ... so far.
O'Sullivan 12-9 Si (0-13)
Can Si win four on the spin? It seems unlikely, but he gets away early in frame 22...
O'Sullivan 12-9 Si
If Si loses this, he'll have regrets – he's had a lot of chances, but neither his technical game nor his mental game aren't quite ready for the kind of pressure playing Ronnie at the Cruce necessarily entails. Still, though, what a clearance from the boy Ronald.
O'Sullivan 11-9 Si (32-54)
Ronnie looks a long one up and down – it's almost the full length of the side rail, close to it ... AND WHAT A POT! That might just tip the match irretrievably, though green to brown won't be easy ... but TMNTPETPUAC makes it look easy! Again, he raises it when he needs to!
O'Sullivan 11-9 Si (29-54)
Si's break comes to an end when he runs out of position, then a few shots later he takes a wild thrash at a pot – that's one reason it's hard to see him winning – misses by miles, almost flukes it, and when it stays on the lip, Ronnie gets going. This is the kind of clearance that's got him this far, finding it within himself to punish an opponent's errors. But as I type, he misses an awkward red to right corner but leaves nowt, and the frame remains in the balance!
Judd Trump beats Luca Brecel 13-8
Amazing behaviour from an amazing genius. Judd was in trouble at 5-7, but he won eight of the next nine frames and when he plays as he did, he's far too good for everyone. He meets Mark J Williams in the last four, while Luca goes home, hopefully feeling good anbout himself – he's given us a(nother) great tournament.
O'Sullivan 11-9 Si (9-54)
It's not felt like Si believes – really believes – he can win this match. But he's surely seen enough of Ronnie tonight to revise that; the eway he's playing certainly suggests that. Oh, and Luca misses brown to middle! Judd needs that, blue and pink for the match...
O'Sullivan 11-9 Si (9-36)
On table two, a rash shot from Luca offers Judd a chance to clinch the match – but there's a red on the side, with blue and black chilling opposite. So he sets himself for a double, and the position is ideal ... but the ball won't drop. Meantime, Si accumulates.
O'Sullivan 11-9 Si (9-8)
We wondered earlier and we're wondering it again: is this Si's night? He flukes an unlikely plant and lands on the yellow, dispatched via rest, which takes him up the table; can he make the opportunity count? The black's tied up, but the pink is free as a bird.
O'Sullivan 11-9 Si (9-5)
The balls are pretty nicely spread now, "but not for the next shot," reckons Fouldsy ... then Ronnie glides from centre to left corner, only to miss a much easier ball. Pressure is mounting and he doesn't seem to be enjoyoing the experience, but gets lucky, leaving nowt.
O'Sullivan 11-9 Si (4-5)
A good safety from Ronnie leaves Si in trouble near the baulk rail, but even so, who expected him to hit the brown? He plays a better shot next go and gets the points back when The Rocket misses a thin contact.
O'Sullivan 11-9 Si (0-1)
This frame is colossal: if Ronnie takes it he's almost home, but if Si does, it'll get really nervy. And again, it's Si who pots the first red – after another error from Ronnie – but he lands on nowt, then a futher mistake – this time a pot missed by weeks – leaves nothing. So far, the interval seems to have changed nothing

On table two
Trump 12-8 Brecel
Judd sweeps the session in unbelievable, believable style. At the start of the competition it was hard to see how anyone could beat him, and it still is.
O'Sullivan 11-9 Si
This is the best I've seen Si play in a while; he's still in dis ting. See you in 15.
O'Sullivan 11-8 Si (0-68)
This is a really good break from Si, who makes the frame safe; he needed to win this session and he has. Ronnie returns to the table needing three snookers.
O'Sullivan 11-8 Si (0-35)
Si breaks the pack off the blue and it works out nicely; this is a areally good chance to narrow the gap once more.
O'Sullivan 11-8 Si (0-22)
Again, Si gets in at the start of a frame, breaks the pack ... and all he's on is one long to the yellow bag. Last time he attempted similar, he fluked it into the middle; this time he hits the jaw. No matter: he's soon left the thinnest of cuts to left corner, striking hard to force it home, but with a red over middle he must bag the blue he's about to send long .. and that's a gorgeous pot! Can he keep focused enough to make this visit count?

On table two
Trump 11-8 Brecel
Both players have had chances, but it's Judd who claims the frame. This is a proper sonning off ... so far.
O'Sullivan 11-8 Si
Ronnie goes two away, and I just don't think Si is playing consistently enough to get close enough. Zhao, his potential semi-final opponent, would be a different thing.
O'Sullivan 10-8 Si (69-28)
Ronnie secures the frame, and will feel much better for it. As we keep saying, he's brilliant at doing just enough.
O'Sullivan 10-8 Si (46-28)
Oh that's lovely! Ronnie slots yellow to its own pocket, breaks the pack or what remains of it, the split is lovely, and this is surely going to be his first frame of the evening.
O'Sullivan 10-8 Si (16-28)
Ach, Si loses the white, so doesn't get value for his fluke, and that's better: Ronnie strokes home an opener, finishes on the black, and this is a crucial visit. He gets the pack open, concentrates really hard on a nasty black, and this might be him doing what he does,taking care to win a frame when he really needs to.
O'Sullivan 10-8 Si (0-24)
Si's feeling himself now, smoking a starter to right corner but, finishing on the side, dare he attempt the black? It's not clear what his next red would be, but he sends it down anyroad, then tries to send one long to the yellow bag, clipping the blue before he even reaches it ... then it rolls into right-centre! Outrageous! This game! And is it Si's night?
On table two
Trump 10-8 Brecel
Two frames, two tons, and Luca needs to get involved, fast.
O'Sullivan 10-8 Si
Ronnie hasn't got going tonight, and as we said below, he's got form for beating himself in this kind of situation. I know narrative says Luca blitzed him in the 2023 quarter-final comeback, but he was given a very hefty push – he'd been handed a couple of frames before he got going. If si can win the next, we'll really be talking.
O'Sullivan 10-7 Si (1-74)
Si makes the frame safe. Is he starting to believe?
O'Sullivan 10-7 Si (1-54)
Goodness, a miss apiece, Ronnie's coming second – a straight mid-range diag to corner – and si has a chance to close the deficit by one more.
O'Sullivan 10-7 Si (1-40)
On the other table, Judd has registered another ton, so he's now out on his bill with 104; where will it end? What a total expletive genius. Oh, but as he trots off, Si slinks back to his seat – he's missed a red to corner and left it on the lip. But Ronnie then misses a black off its spot! He leaves nothing, but, so with reds spread we're playing safety.

And Judd, at the table potting, leads 26-0.
O'Sullivan 10-7 Si
When Si misses, Ronnie returns to the table to get his arm going. So far in this competition, every time he's needed to win a frame he has...
O'Sullivan 10-6 Si (1-60)
Yup, Si makes it safe.
O'Sullivan 10-6 Si (1-45)
Si sinks another red to right corner, then nuzzles the yellow; Ronnie lands on his red of choice but leaves it, and this could well be the frame.
O'Sullivan 10-6 Si (1-38)
On table 2, Judd has settled, making his 103rd ton of the season; that's level with Neil Robertson's record, and who'd back against him surpassing that before the night is out; before the next frame is out? Meantime, Si misses to right corner, but leaves nothing.
O'Sullivan 10-6 Si (1-19)
Ronnie begins with a red floated to left corner but on nothing, he plays safe off the brown. Then, a few shots later, he misses to right corner but with safety in mind, such that Si has no choice but to attempt a pot himself ... and slides a decent effort into right corner. He looks ready for this.
Out come our players
Let's be avin yer!
Our outsiders tonight
Both Si and Luca are, when at it, phenomenal potters. That gives them a chance in any match against any opponent – even the two greats of game they face tonight.
Table 2
This match could mature into an all-time classic. Judd Trump and Luca Brecel, two incendiary potters and former champions in great form, each of whom has been on the cusp of disaster before battling back such that we're now level at 8-8. I've not a clue what's going to happen next, but I can't wait to find out.
Table 1
This looks a lock: Ronnie O'Sullivan leads Si Jiahui 10-6, with just three frames required for victory. However, he's lost from precisely this position to Peter Ebdon, Anthony McGill and Luca Brecel and isn't playing so well it's inconceivable. If Si hits a streak – and he's streaky – I'd not be entirely shocked if Ronnie helped along by almost beating himself.
Hello there!
And what an evening we have in prospect!
Evening session
After the dramatic end to their afternoon session, Trump and Brecel have a short break before returning to play to a finish on Wednesday evening.
On the other table, Ronnie O'Sullivan returns holding a 10-6 lead over Si Jiahui.

'I just kept playing Tom Jones over and over'
Mark Williams was feeling drained when he arrived at the Crucible, but revealed a secret weapon that kept him in the zone...
"Balls of steel!" he joked. "It was such a tough shot [on the blue]. It was probably thinner than it looked. It could've gone in-off, I could've over-cut it. I've just gone for it full-blooded and landed straight on the pink and black.
"There wasn't one bit of nerves or shaking; I don't really get that. I just don't know any different, to be honest.
"I didn't think John was going to miss. From 12-8 to 12-12, I'm sat there and haven't done anything wrong really. I was thinking: 'what can I do?'
"I felt drained this morning because we had two tough sessions [on Tuesday]. I just kept playing Delilah and A Boy From Nowhere by Tom Jones over and over when I was getting ready. I was still playing and singing them in the dressing room just to try and stay with it because it's tough out there, especially the older you get.
"I've got to enjoy it because I don't know how many times I'm going to keep coming back here."
'Every credit to him'
John Higgins was as gracious as ever, despite his heartbreaking defeat.
"I had the chance on the blue," he said. "It was difficult, and you're struggling to see the pockets at the end of the game.
"He potted a great blue, pink, black, so every credit to him. He's a great champion.
"I still felt good going into the last frame. Mark had a great pot and I thought he would do what he always does. Then, I had a chance, but I could only make 30.
"Then, I made a bad safety when I was in control of the frame. I got my chance, but I couldn't take it.
"I've had a good season, the atmosphere out there was incredible, a standing ovation walking in. There's no better place to play, win or lose."
Williams wins
All credit to the three-time world champion, who led 12-8 before he was taken the distance.
But as he has done so many times, the 50-year-old held himself together to deliver under the most intense pressure.
Williams has now won five of his six meetings with Higgins at the Crucible.
His reward is a showdown with either Judd Trump or Luca Brecel in the last four.
RESULT! Higgins 12-13 Williams
Another blockbuster clash between two of snooker's all-time greats goes right the way down to the final black.

Higgins opens with 40 before missing a tricky red to the left corner.
Williams then counters with 73 to edge his nose back in front.
Three of a kind?
Si has a chance to follow in Ding Junhui and Marco Fu's footsteps and become the third multiple Crucible semi-finalist from Asia.
However, the 22-year-old must improve and start taking his opportunities if he is to have any chance of doing that.
O'Sullivan 7-2 Si
A run of 43 is more than enough for O'Sullivan to take the first frame of the morning session.
He is now five frames to the good.
O'Sullivan 6-2 Si (29-8)
Although, misses like that won't help his cause!
Si misses a straightforward pink to the right corner, pulling it to the near jaw.
O'Sullivan 6-2 Si (29-0)
But he can't take it...
O'Sullivan drifts slightly out of position and is left bridging over a red near the right cushion.
He subsequently misses the black, and this is where Si needs to step in if he is to come back in this contest.
O'Sullivan 6-2 Si (20-0)
The Rocket with his first chance of the second session.
He needs to develop some reds around the pink spot, but this is a decent opportunity.
