Humphries 1-0 Kenny (0-1)
That is some leg from Nick Kenny.
He starts with a 140 before adding his first 180 to really take control against the darts.
A dart at the bull misses but a frustrated Luke Humphries is well back so Kenny goes back and hits double eight for the early break in the second set.
Humphries 1-0 Kenny
That first set was won against the throw by Luke Humphries so Nick Kenny's task is that much harder from here.

Those are the kind of opportunities that Nick Kenny is going to have to take if he's going to be competitive here.
That is the first leg that Humphries has dropped in this tournament.
Humphries 0-0 Kenny (0-1)
Luke Humphries is quickly into his business with the first 180 of the match.
He then leaves himself 32 but goes on to miss three darts at double 16 and give Nick Kenny the chance to hold.
And Kenny does so brilliantly, hitting double 14 for a 105 checkout.

Luke Humphries wasn't pushed on the opening night, he just wanted to win and he wasn't bothered around the performance. He's back now and wants to defend his title.

The same goes for Luke Humphries as the world champion walks on to I Predict a Riot by Kaiser Chiefs - the walk-on song he brought in during this year's Premier League.
It's going down well as he does a bit of conducting for the crowd before heading to the oche for a few practice darts.
A very decent wage, if you're at the top level.
Luke Humphries would become the first player in PDC history to reach £2m on the two-year Order of Merit system if he clinches back-to-back World Championship titles on 3 January.
Both he and Luke Littler have trousered more than £1m in prize money this year, and they will earn more through sponsorship deals, merchandise and exhibitions.
Humphries v Kenny
Image source, Rex FeaturesThe final match tonight see Luke Humphries continue his bid for back-to-back world titles.
After winning the battle of the Lukes in last years final, beating teenage sensation Littler 7-4 at Ally Pally.
Humphries is top seed this year and remains on course for another showdown with Littler in the semi-finals.
To get there, though, he first has to get past Newport's Nick Kenny.
Peter Wright talking to Sky Sports: "Jermaine felt sorry for me obviously! It [the chest infection] wasn't affecting my darts, I was just holding my breath.
"I'm not bad for an old guy, am I? It is about spirit and the support was brilliant. Hopefully I'll be feeling a little bit better in the next round."
Wattimena 2-4 Wright
Peter Wright is being interviewed on the TV and is struggling to answer between coughs.
Shows how deep he had to dig to overcome Jermaine Wattimena - who played very well - and really show his class in the big moments.

The realisation is just kicking in for Peter Wright. You can tell he's really struggling.
I've seen a lot of Peter Wright but that is one of the best performances I've seen for a long time.
Wattimena 2-4 Wright (1-3)
Peter Wright has done it!
Ill, out of form but still a world champion. Snakebite produces a marvellous performance to reach the fourth round.
There are tears in his eyes as he waves to the crowd. It could be the illness but that is a big win for Wright.
Wattimena 2-3 Wright (1-2)
Jermaine Wattimena is up against it but he is not giving this one up any time soon.
Double eight gives him the hold he requires and means Peter Wright will have to hold throw to win this match.

This is an astonishing display from Peter Wright. He's proving that he's still one of the best.
