Van Gerwen v Merk
Mark Webster
Former BDO world champion on Sky Sports
It is a game that I think Michael van Gerwen will win, but because of what is next - Gary Anderson - he'll want to put on a show. His run should allow him to build up some form.
Van Gerwen v Merk
Adam Millington
BBC Sport journalist
Michael van Gerwen says Peter Wright should retire after his emphatic defeat in the second round of the PDC World Championship.
Two-time world champion Wright won just two legs and averaged below 80 as he was surprisingly beaten by debutant Arno Merk on Tuesday.
Van Gerwen, who has won the world title three times, said he was "not surprised by [Wright's] performance" given the Scotsman's inconsistent recent record and "it's time for him to retire anyway".
Wright, who became world champion in 2020 and 2022, has not made it past the quarter-finals of any televised ranking tournament in the past two years.
The Dutchman's comments follow Wright's recent suggestion that Van Gerwen's "vision is probably going".

Van Gerwen v Merk
Dust yourselves down folks, there's another former champion on next.
Third seed Michael van Gerwen faces the world number 163, qualifier Arno Merk.
We have seen some heavy thrashings and some titanic clashes today. Will this one fit either bill?
Humphries 4-2 Clemens
Luke Humphries talking to Sky Sports: "For me, I thought when I missed the double to go 3-0 up, I don't think I really dropped off but Gabriel got a lot better. If that double 13 doesn't go in, it is 3-3 and I'm panicking. That could be the difference between being world champion again or not. I just found another level there when I needed it.
"I felt like I was searching at times with the first treble going in and then not the second. I found them in the right moments at certain times. He put me under pressure and that's what you need to do against me and Luke Littler. I'm through and that is amazing for myself."
Clemens records 10th highest match average - but loses
Humphries 4-2 Clemens
That bull, 25, bull out from Clemens will live long in the memory. That was what sparked the comeback.
The German averaged 101.49 in defeat. Humphries also averaged in three figures.
Humphries 4-2 Clemens
A hug between Luke Humphries and Gabriel Clemens, such mutual respect.
Clemens should be very proud, the way he fought back from being totally out of that match to push the second seed to the very edge.
Few players will play as well as that in defeat at these championships.

Humphries 4-2 Clemens (3-2)
Knocked in with D13!
Luke Humphries jumps and roars - I have not seen a celebration this big from him since he won the title in 2024.
That shows how hard he had to work, and how much this means to him.

Nobody would have seen this coming from Gabriel Clemens. People know he is a good player but this has been brilliant.
Humphries 3-2 Clemens (1-2)
Clemens is averaging just over 100 in this match, Humphries just under a ton.
Humphries though now leads in 180s, setting up a 108 finish. He can't get it though.
Clemens requires 68... banged in via D16!
A massive break - if Clemens holds the next leg, he levels the whole match.

It has been all Gabriel Clemens in the past 10 minutes.
Humphries 3-2 Clemens (1-1)
13 180s in this match, seven of them by Gabriel Clemens. We did not expect this when Luke Humphries went three sets ahead.
But now Humphries is on seven 180s! He puts big pressure on the Clemens throw.
Clemens needs 97, Humphries lurks on 52.
But Clemens slams in tops. Cool under pressure from Cool Hand Luke.

So Humphries has three darts at D10... all missed!
Clemens though spurns a 110 finish, so Humphries is not punished.
Humphries 3-2 Clemens (2-3)

That is what Luke Humphries can do!

That is how you apply pressure!
A 170 checkout, and that means that if Humphries breaks throw here, he goes through.
