That felt like another excellent chance for Bunting to break.

Not exactly a classic, this.

180 leaves 61. He has two darts at double 18, but, as is to be expected in this match, he misses both.

Luke Littler then misses a dart at double six to win the leg with 129 left.

Bunting just about manages to wrap up the leg, taking out double nine with the third dart of his throw after going inside on the 18s.

The competitor in Luke Littler, this will fire him up and into action, I'm positive.

But with this start, Bunting can make life uncomfortable for Luke.

Stephen Bunting is first down to a finish, albeit 164.

He can't take it out, leaving 68, but Littler doesn't provide too much pressure, getting down to 68 himself.

But wait, Bunting can't check out 68 as he misses a dart at double 16...

Then Littler misses a dart at tops to let Bunting back in.

Bunting can't check out 16 in three darts and is down to double one. Littler finds the checkout, eventually.

Ample chances for Bunting to win that one.

Nearly! Stephen Bunting finds the first two darts as he looks to take out 170, but then hits the outer bull.

Luke Littler is all the way back on 287, so it's no surprise that Bunting wraps up the leg. He only needs one at double eight.

Stephen Bunting gets himself down to 96 left, Littler then gets it down to 110 remaining.

Bunting can't check out and sets up a finish on double four. Littler then can't find a treble with his next visit.

Bunting takes it out with his first dart. A 74 average for Littler in that leg.

Quite a few boos for Luke Littler form the Brighton crowd.

He'll be looking to silence them in this one. The world number one gets us started.

Luke Littler is looking to repeat last year's antics as he takes to the stage in Brighton this evening.

He beat Gerwyn Price, Michael van Gerwen and Nathan Aspinall to win the night last season.

Tonight, he takes on Stephen Bunting, who he won 6-3 against in Berlin on night eight.

Stephen Bunting, speaking to Sky Sports: "I saw what happened and I'll stay out of that sort of stuff.

"If he celebrates me missing doubles... I know Luke pretty well and I know he wouldn't do that to me. I don't think there was any malice in it."

Luke Littler, speaking to Sky Sports: "Everyone is looking to the semi-finals and me and Gian could meet but I'm just focused on Stephen [Bunting].

"It's his birthday and he'll be wanting a birthday win.

"If [Gian and I] do meet then whatever happens, happens but I've got to win first.

"I just want to get back to winning ways, it didn't go my way last week."

Gerwyn Price may have won in Manchester, but the biggest talking point was Luke Littler's antics in his match against Gian van Veen, which led the Dutchman to accuse him of being "out of order".

If they win their quarter-finals, against Stephen Bunting and Michael van Gerwen respectively, they will meet in the final four tonight.

Last week, the Dutchman turned his head in disappointment after missing double 15 for the match in the deciding leg and saw Littler celebrating.

That led to an angry reaction from the world champion, who gestured for Van Veen to get on with it.

Littler then proceeded to miss two more match darts of his own before making a 'cry-baby' mime to the crowd.

But Van Veen held his nerve and hit double six for the match. The briefest of handshakes followed before Littler marched off.

Another pinch in this game.

Little things are happening now with Josh Rock. There was a point in the early weeks where it felt nothing was going his way.

You need a bit of luck.

Gerwyn Price misses three darts at double 15 to win the leg, going inside with his third.

Josh Rock then can't finish himself, missing a dart at double 18.

Very poor from Price with his next throw, though, getting 13 with 15 remaining.

Rock manages to check out on his next visit to go one leg from victory.
