A nod of the head from Ronnie O'Sullivan signals that he isn't thinking of getting out of his chair. Kyren Wilson's break of 62 is his highest of the match so far.

That's a lot better. Kyren Wilson rattles a red into the bottom corner with the rest as he heads towards a break of 50.

Is he settling into this final now? This feels a bit more like it.

You really feel that Kyren Wilson has to make the most of this opportunity. He really needs to up his game here.

Both players are having a pretty tough time in the balls at the moment. Kyren Wilson missed a pink he'd normally expect to gobble up. And Ronnie got no further than 13.

What is going on? Just as I type that Wilson is back on the baize and in the balls.

Absolute result that Lee. Brilliant perseverance.

Kyren Wilson misses a long red into the bottom right before getting another chance with the rest.

His cue action is all over the place there though. Looks like a re-rack.

Where's that Joe Davis book Ronnie has been on about? It could come in handy at the moment.

The players are back. Here we go again.

Kyren Wilson has been doing his thing on the practice table. He's got a bit of fine tuning to do to get back to the form that saw him beat Judd Trump in the quarter-final...

Josh Robinson: More interesting than quality so far. Ronnie’s foundations of his game (break building & cue ball) are on form but the “other stuff” - safety/tough shots - are absent. Kyren’s foundations (long pots & rest shots) are eluding him, he’s getting by with his “other stuff”.

Talking of John Higgins, his victory stirred up really emotion when he won his fourth World Championship in 2011 two months after losing his father.

Today is the 21st final in the 21st Century.

Out of those, Ronnie O'Sullivan, Mark Williams or John Higgins, who all turned professional in 1992, have featured in 15 of them. A fine vintage.

I think it's nerves. The interval has come at a good time for Kyren Wilson.

Early alarm bells for Kyren Wilson. I know it’s first to 18 frames and it’s only 3-1 but if he’s going to miss one of his most reliable shots by that distance then it’s early warning signs.

If you make a mistake against Ronnie O'Sullivan you know it could be the last mistake in the frame, and that has been the case a couple of times already.

Meanwhile Ronnie O'Sullivan racks up a break of 75 and takes another frame.

That's four frames done in just over 57 minutes.

The mid-session interval is coming up, so time to get the kettle on.

That was a rare sight, seeing Kyren Wilson missing with the rest. I think the brown was distracting him slightly.

Oh no. Out comes the equipment and there goes Kyren Wilson's break.

He was impeccable with the rest in his win against Judd Trump but an attempted red into the bottom left corner rattles in the jaws.

Bad miss that. And even worse, Ronnie O'Sullivan is in prime position.

Nikita: If this Final is anything close to last night's semi-final there's every chance I could go into early Labour. Super pumped up watching Ronnie & Kyren and even bump is kicking away frantically, very excited little boy!!

Scratch that last entry.

Kyren Wilson misses an absurdly difficult red into the top bin but Ronnie O'Sullivan, for once, does not capitalise.

Decent chance for Wilson to get his cue arm going here.
