Whatever happened in the crowd there, Luke Littler is far from happy.
Littler 0-1 Noppert
Luke Littler hits seven and gives it to the crowd. He's distracted here and needs to pull himself together.
Littler 0-1 Noppert
Luke Littler leaves 104 but misses the treble 16 at the first time of asking. He finds the target but takes a step away after a shout from the crowd. He then goes low on tops and gives Noppert a chance. Littler is seething here.
Danny Nopper nicks the leg and Littler keeps shaking his head.

Luke Littler's main aim is to win darts tournaments. He wants to be ruthless.
He just wants to keep winning and winning. He just sees it as a box-ticking exercise.

Danny Noppert is Mr Consistent at the moment. He's just good on TV. He's progressing nicely. He's hitting a lot of 180s and he wants to be an elite player. He's a good guy and he's doing good things.
He'll dictate the pace against Luke Littler and that might be something to watch.
Luke Littler v Danny Noppert
Danny Noppert has made the walk to the stage and here comes Luke the Nuke Littler.
Think everyone in the country knows his walk-on song now!
Luke Littler v Danny Noppert
Danny Noppert talking to Sky Sports: "I have to play like I did against Michael van Gerwen and I would have a good chance to win. I have to show my best to Luke Littler or otherwise I'll get smashed."
I reckon we're seeing a nine-darter today.
Keep the faith guys!
Luke Littler v Danny Noppert
Luke Littler, speaking to Sky Sports: "It's massive. I know if I do get the win then I progress to the final, but I'll become the new world number one. I'll be happy.
"He [Danny Noppert] had the better of me in Hungary but I didn't turn up. He got me on a bad day. The way I played last night, I don't think there will be another bad from me now."
Result: Humphries 16-13 Price

Image source, PA MediaIt was a brilliant display from Luke Humphries and doing that for 29 legs is incredible. He deserved to win the game.
Gerwyn Price gave it everything but at some stage you are going to crack, you can't keep relying on ton-plus finishes.
That was title-winning form from Humphries though.

What a semi-final!
Luke Humphries marches on after a stunning performance, averaging 106.25 with 16 180s.
One unnecessary mistake - trying to finish tops, tops - gave Gerwyn Price a chance in that last leg but, for once, he couldn't take it and Humphries seals the win.
Result: Humphries 16-13 Price
Luke Humphries, speaking to Sky Sports: "It was a fantastic game of darts. I said I like playing him. he gives it the big one but you need people like him in this game. He goes under my skin but I got him. Such a tough player to beat. He stayed in there and I showed a lot of resilience in the end. I've got to bring that tonight.
"Sometimes you want to give a little bit back. He makes you want to be better but I keep my emotions in check. He was getting revved up. He said my scoring is so relentless and he couldn't deal with it. When he's on his game, he's a match for anyone.
"I feel there's more to give. I believe I can put it up higher. This could be my last day as world number one, who knows? I've been so happy and proud of myself but it's not about that for me. I want to pick up this trophy that started my career.
On Littler: "I hope he wins because he's probably going to take it off me anyway. A great final between me and Luke is in prospect. It's a war now, I'm going to try and take it back."

It was one of the great individual performances from Luke Humphries from the first dart to the last. His scoring power was off the chart.
Fair play to Gerwyn Price. He hung in, some of his clutch finishing was up there with the very best but Luke Humphries was sensational and his scoring was the catalyst for his success.
It was a wonderful performance from a great player.

That was a performance of the utmost class and brilliance from Luke Humphries.
Humphries 16-13 Price
Image source, PA MediaLuke Humphries is miles in front of Gerwyn Price against the throw.
Humphries, on 140, goes treble 20 and looks for tops, tops but misses.
He can't check out again and now it's Price's chance. Can he take it? No.
Humphries nails double five to progress.
Humphries 15-13 Price
Luke Humphries follows his opening 180 with another 180. He couldn't hit a nine-darter, could he?
The answer to that is no but he checks out 86 for the 12-darter.
One leg away.

Gerwyn Price just will not go away. Luke Humphries was the width of a wire away from a 15-11 lead and having one foot in the final.
Suddenly, Price is back to within one and it's anyone's game again.
Humphries 14-13 Price
There's one in it!
Gerwyn Price hits double 10 to pile the pressure on.
What pressure, though? Luke Humphries lands a maximum to start the leg.
