Our fourth quarter-final tonight sees Stephen Bunting continue his search for a first Premier League win of the season as he faces Nathan Aspinall.

The Asp is only a point off the play-offs after winning five points in the last couple of weeks, and had a nice run to the UK Open quarter-finals at the weekend.

The Bullet has had ton-plus averages in his last two games and generally played well throughout but has come away empty handed - and is in danger of being cast adrift if he can't turn things around.

Can he get his first win here?

That was a brilliant nine-darter from Luke Humphries - well they're all brilliant aren't they but he just threw all of those nine arrows so easily and so quickly, once the seventh treble 20 went in it never looked in doubt.

But credit to Rob Cross, who responded superbyl and ended up with a fine 111.19 average and seven 180s - he'd only hit 11 of them in four weeks before tonight.

Cross was also hot on the doubles hitting six out of 10 - that's a deadly combination even against a men who throws a nine-darter.

Phew, that was breathless stuff, for those that could see it anyway, with a nine-darter, almost a 170 checkout and a big comeback all resulting in world number one Luke Humphries losing his opening match in the Premier League for the first time this season.

Rob Cross makes his third semi-final of the season and will face Stephen Bunting or Nathan Aspinall.

Rob Cross completes a fine comeback against nine-dart hero Luke Humphries to go through to the semi-finals.

Voltage trailed 2-0 and 4-2 against the world number one, but managed to reel off four straight legs to seal victory against the Premier League leader.

Both have 85 left, both miss it at their first attempt but Rob Cross gets the first chance to finish off the leg, which he takes with double eight to lead and go one away from victory!

Four each. What a match this is.

Lovely 116 checkout for Rob Cross as it's a big swicth from treble 19 and big 19 back up to tops, but he hits it to level the match up.

Rob Cross gets back to within one as he breaks right back thanks to an 87 checkout finished on his favourite double 18.

A 180 helps Luke Humphries to move two ahead in what's another scrappy leg that's settled in 17 darts - but the world number one won't care.

Luke Humphries almost adds the maximum checkout of 170, the big fish, to his nine-darter but he can't find the bullseye to finish it off.

Rob Cross misses double 10 and double five though when trying to take out 80 so Humphries can return to go back in front.

As often happens after a player hits a nine-darter, Luke Humphries has just suffered a dip with that rush of adrenaline that was no doubt flowing through him just draining away.

Rob Cross has taken full advantage and hit three straight 140s to help him win a 13-darter to level the match.

That was the 17th nine-dart leg in this history of the Premier League since its inception in 2005.

Rob Cross gets on the board with a brilliant leg of darts of his own - winning it in 11 darts but it gets just a ripple of applause as it looks rather pedestrian after that nine-darter...

Luke Humphries is on a nine-darter!

A 180 start for Rob Cross, but it's Luke Humphries that takes the opener on his own throw as he hits double eight to clean up 76.

Side note - Luke Humphries is a very enthusiastic hugger up there on stage - Rob Cross gets a very affectionate cuddle from the world number one.

'Massive apologies for the loss of pictures,' says Sky Sports presenter Emma Paton.

Before the pictures are lost again.

Rob Cross hails from Hastings just an hour along the south coast from Brighton, and he hopes familiar surroundings can help him exact revenge on Luke Humphries.

The 2018 world champion had the world number one on the ropes last week before a stunning finish from Cool Hand Luke - and Cross is still kicking himself for missing chances to seal the deal.

“I always enjoy playing Luke,” said Cross. “I missed a trick against him last week, missing four doubles in one leg, but that’s part and parcel of the game.

“We usually seem to perform against each other, so I can’t wait to get up there and hopefully get over the line.

“It would be absolutely fantastic to get the win tonight. I have some fond memories here. I love Brighton, it’s a special place.

“I will have a few friends in the crowd. They have messaged me, so hopefully I get plenty of support and the right result!”
