And then there were two.

A lot of people predicted Luke Humphries - winner of several tournaments already this season - would be in the final at the Ally Pally.

But few, if any, forecast, the remarkable rise of 16-year-old Luke Littler.

Both produced outstanding performances tonight to book their spots in the showpiece - and we'll have live text coverage of the final tomorrow night so join us back here then.

Luke Humphries on facing 16-year-old Luke Littler in the World Championship final:

"The way he's played, I've seen it many times - but when you come up on this stage, it can be a lot tougher, and he's just proved he's got a lot of bottle.

"Nothing is going to faze him - if he played like that tonight, tomorrow is not going to faze him at all.

"So I'll probably have to play the game of my life to stand a chance of beating him. I know what's in front of me, I've got to play at my best.

"But I'm hoping I make him play at his best and we give the fans one of the best world finals that's ever been seen."

More from Luke Humphries to Sky Sports:

"I felt amazing yesterday and in the practice room I felt even better.

"Yesterday [quarter-final win over Dave Chisnall] gave me the confidence. I hadn't really put in a statement performance until then and a lot of people probably didn't think I stood a chance after my first couple of games, which was fair enough,

"But I've come back well - I almost went out but I've then put in two really good performances and I'm really excited to be in my first world final."

Luke Humphries, who rises to number one in the world by virtue of reaching the final, speaking to Sky Sports:

"It feels amazing. I would never have imagined myself to be the world number one, that is a special, special feeling.

"And to do it in style - I was really pleased with that performance there.

"But like I've said in many, many, many interviews, world number one can last a couple of months, world champion is forever and I've got a really tough task tomorrow against Luke [Littler]."

Luke Humphries averaged 108.74 in that semi-final.

If you're a casual darts fan, let me tell you - that is earth-shattering stuff.

In fact, the comms have just said it is among the top 10 World Championship averages of all time.

What a performance from Luke Humphries.

He has absolutely taken Scott Williams apart with a display of brutal scoring and fine finishing.

Williams didn't even play that badly - the third seed was just unstoppable.

What a final we have on our hands on Wednesday night - the battle of the Lukes: Littler v Humphries.

Humphries has six darts from 180 - hits 100.

Scott Williams is disconsolate.

He hits two treble 19s to leave double six - but busts it with double 10. Back to 126.

Of course Luke Humphries punishes him - 180 and double 15 next visit. Sums up the match.

Well done, Scott Williams - Shaggy breaks back with a double 18 finish.

Keeps alive his chances of avoiding the 6-0 shut-out.

Another break of throw sealed with double 20.

Luke Humphries two legs away from a final against Luke Littler.

Luke out, darting world, Luke out.

John Jefferis: Luke Evans has been in fair amount of big films.

Hmmm. I'll allow it...

This would be the greatest comeback of all time if Scott Williams can pull it off.

Spolier: I don't think it's going to happen.

Another clean sweep of a set for Luke Humphries who is really justifying his position as pre-tournament favourite.

He is demolishing Scott Williams on the Ally Pally stage.

See, we're reaching a bit aren't we? No offence, Luke Wright.

There just aren't many famous Lukes.

Darts is changing that narrative tonight.

Hassan Waqie: Anyone for Luke Wright???

Very much After the Lord Mayor's show this match after that amazing opener.

And it's down to the brilliance of Luke Humphries who is just ploughing towards tomorrow night's final.

Double top for the latest break of the Williams throw.

Humphries misses five set darts - but takes the sixth on double two.

Scott Williams had his chance to punish but missed a dart at double 10.

This one looks in the books. Humphries is playing sublimely. Those missed darts in that leg were his first real mis-step.

Luke Humphries hits 180 and then takes out 125 from 305. Stunning.

That's his fifth ton-plus checkout.

But Scott Williams has the throw in the deciding leg - can he get his first set?

Scott Williams is determined to land a 180 with a no-look third dart.

Doesn't happen. Maybe 3-0 down in a world semi-final not the best place for it?

Luke Humphries shows him that actually looking at the board is the way forward with five perfect darts - but Williams still holds throw by taking out double eight.
