It's turning into a blockbluster this.
Humphries 8-7 Price
The Luke Humphries machine rolls on. No emotion from the world number one as he retakes the lead by checking out 104.
Treble 18, 18, double 16.
Humphries 7-7 Price
Now then! Luke Humphries goes maximum after maximum to leave the nine darter but boos ring around as he misses the treble 20.
Absolutely no mistake on the double 18, though.

Luke Humphries leaves 56 with Gerwyn Price on 100.
He hits the treble 20 and hits double tops at the first time of asking.
What a match this is turning into!

Luke Humphries hits two 180s to leave 82 with Gerwyn Price way off it.
He takes his time to check out on tops for a 12-darter.

Gerwyn Price really didn't want the break to come but he's got to pick himself up again and he does just that by hitting tops to take the lead.

The first mini-break did Gerwyn Price the world of good. He is flying now.
Luke Humphries is still looking good but some costly missed doubles and Price has come roaring back - literally after that 151 out - to level.
What a semi-final we've got on our hands here.
Humphries 5-5 Price
Gerwyn Price is on FLAMES!
He celebrates like he's won the match after checking out a superb 151 to win his fourth leg on the spin to level.
Treble 20, treble 17, double tops. Never in doubt.

That is what you can't teach! Gerwyn Price has so much bottle and he has since the first day I met him.
This game is warming up really nicely.
Humphries 5-4 Price
Gerwyn Price starts the leg with a 180. He's feeling it again but makes a bit of a mess of the rest of the leg before banging in the double 20 to go one leg behind Luke Humphries.
Who'd have thought this?!
Humphries 5-3 Price
Is Gerwyn Price starting to get going here?
After winning the leg, he comes back with a maximum to take the lead in the leg.
He leaves the big fish, hits the first two treble 20s but hits the outer ring on the bull.
No mistake when checking out 25. Price is back in it.
Humphries 5-2 Price
Glen Durrant
Former Premier League champion on Sky Sports
It is almost like Gerwyn Price is picking up scraps when he can get them so he may only get one dart at a double.
Humphries 5-2 Price
Oh, how Gerwyn Price needed that!
With one dart left, he hits double tops and gives a bit to the crowd.
Humphries 5-1 Price

How do you beat him in this form?!

Away we go again after the break. Gerwyn Price can't afford to let this slip further away from him. Needs to show resilience here.
