A brilliant 134, with two treble 19s, from England's Rob Cross sets up double 18, which he lands first dart.

Cracking quarter-final that looks like going all the way, first to six legs, don't forget.

MVG goes close to a 170 finish after two treble 20s but misses the bullseye.

Matters not as he tidies up double 16 to move 4-3 up after Rob Cross had previously held his throw comfortably too.

If you missed it folks, 16-year-old Luke Littler hit a nine-darter in the opening leg in beating world number four Nathan Aspinall 6-3 earlier...

Michael van Gerwen is having zero trouble on his own throw.

Another easy hold with Rob Cross nowhere near a finish.

Cracking stuff from Rob Cross who takes out 86 by finishing on double seven, not exactly a go-to double for most players, to cling on to MVG's coat-tails.

Neither player has yet missed a dart at double. Top quality.

Rob Cross' level has dipped momentarily.

Michael van Gerwen holds throw and bangs in a 180 next leg.

'Voltage' responds with a max of his own.

Rob Cross is left with a testing 92 finish to hold throw but makes it look routine, treble 20, double 16.

Shaping up to be another belter in Bahrain.

So, who's going to complete the semi-final line-up and book a last-four meeting with Michael Smith?

Well, Rob Cross was threatening to take the opening leg against throw but Michael van Gerwen stopped him in his tracks with two treble 20s and a double 15 for a stunning 150 checkout.

Can you believe Luke Littler's nine-darter?

Are you over in Bahrain watching in person?

Either way, don't forget to send us your thoughts.

The darting diehards among you will remember Michael van Gerwen's amazing 2018 World Championship semi-final against Rob Cross.

Cross, then a rookie pro, stunned the Dutchman in a dramatic final-set sudden death classic on his way to winning the world title.

But 'Voltage' has struggled to scale such heights since and MVG's dominance of the sport seems a thing of the past too.

Anyway, mustn't forget, there's one more quarter-final to go...

The only other player to ever hit a nine-darter in a World Series of Darts event was Phil 'The Power' Taylor.

He won a few things, you know.

Luke Littler, speaking to ITV4 after his win - and nine-darter - against Nathan Aspinall:

"I'm just glad to win and I think I played really well.

"It's good to get one [a nine-darter] on TV - the first one of the year goes to me. Hopefully I hit a few more!

"I just take it game by game, if I win, I win, if I lose my next game, it is what it is."

Luke Littler averaged 104.50 in that match, which is just stunning.

Let's here from him shortly...

Luke Littler will face former world champ Gerwyn Price in the semi-finals later tonight, readers.

That, folks, is going to be a belter.

With Nathan Aspinall threatening yet another break of throw in this seesaw quarter-final, sitting poised on 75, Luke Littler calmly takes out a 116 checkout.

Jaw-dropping composure from the 16-year-old.

A nine-darter to start the match, a ton-plus checkout to end it. Against the world number four. Running out of superlatives.

He's loving life on the big stage in the World Series is Luke Littler.

Luke Littler was on another nine-darter after six darts.... but the seventh dart drifts into treble one.

Shame but it doesn't matter in terms of the leg as Luke Littler moves within one of victory.

Just when you think Nathan Aspinall is out of the match, the world number four puts in a big score.

Huge 180 and an 81 checkout to break the Littler throw.

Going to the wire, this, surely.

Nathan Aspinall is regularly hesitating on the doubles.

No such trouble for Luke Littler who lands double 18 to break throw again and go two legs ahead.
