Just two places left to fill in the quarter-final line-up now. You have to say that the top half of the draw has opened up very invitingly for a certain Mr R. O’Sullivan...

Quarter-final line-up:

• Ronnie O’Sullivan v Luca Brecel
• Anthony McGill/Jack Lisowski v Si Jiahui
• Mark Allen v Jak Jones
• John Higgins v Mark Selby/Gary Wilson

Not exactly an all-time classic afternoon session at the Crucible but Si’s win means there are just two matches left to complete in the second round before we know the full quarter-final line-up.

Both matches are first to 13 and Anthony McGill and Mark Selby appear to be heavy favourites to advance given their healthy overnight leads.

Evening session line-up (play resumes at 7pm BST):

• Anthony McGill 11 v 5 Jack Lisowski
• Gary Wilson 6 v 10 Mark Selby

Si once again looked so impressive in dispatching Milkins with the minimum of fuss. He’ll fancy his chances of reaching the one-table set-up on debut by beating most likely Anthony McGill in the quarter-finals.

Not since Matthew Stevens in 1998 has there been a Crucible quarter-finalist this young but the world No 80 plays with a maturity far beyond his years.

Si has won all three of his previous meetings with McGill - the length of these World Championship matches means it will be a different sort of encounter, but that hasn’t seemed to trouble the 20-year-old so far.

He’s the youngest Crucible quarter finalist for 25 years.

It was a little nervy at times in the last couple of frames, but that’s a sizeable win for Si, showing his talent and big-game bottle to reach a second quarter-final of the season. Anthony McGill, who starts tonight’s evening session with a commanding lead over Jack Lisowski, is all but certain to be his last-eight opponent - McGill likes the Crucible and has looked in good touch, but you’d give the young Chinese player every chance of at least challenging the Scot.

What a way to finish, too, the last red beautifully guided home and then the black slammed in too to bring up a 100. The yellow and green make 105 - Si Jiahui is through to the last eight!

And in goes frame ball. Si Jiahui will be a quarter finalist on Crucible debut.

Si takes an extra second or two over his shots, keen not to repeat the error he made two frames ago with the chance to seal his place in the quarter finals. But his head drops as he fails to put quite enough on a positional shot to the pink, ending up on the wrong side.

That’s good salvaging, though, playing with top spin and a touch of side to get on a red on the cushion.

That’s the extent of the early scoring, though, with both players sitting in and playing safe. Milkins eventually chances his arm, cuttign a red between pink and blue and up past the yellow, but a bash of the mandibles and its away.

Si doubles his tally with the chance to build a score of substance.

Si won’t be overly concerned by this Milkins rally yet, particularly given the Englishman isn’t playing truly outstanding snooker, but he would ideally like this wrapped up before the mid-session interval. He starts smartly with a lengthy red.
