Clinical finish from Nathan Aspinall as he levels with a 70 checkout.

He gave himself one dart at tops, hit and on we go.

Both players are averaging 102 at the moment. There's nothing to choose between them so far.

Rob Cross is back in front as he coolly takes out 61 in two darts.

He left himself a couple of darts at double 18 but only needed the first of them.

We've seen in this match, maybe not the huge scoring, but how important steady scoring is.

We're seeing very decent averages.

Both over 100 at the midway point of leg five...

Rob Cross hits the first 180 of the match to leave himself tops and when Nathan Aspinall misses bullseye, he gets a shot at it.

He misses on the inside but adjusts to hit double 10.

Level again.

Nathan Aspinall is the wrong side of the wire on the bullseye for a 161 out.

He gets another visit, though, and hits double eight for the first break of the match.

Having left himself a 75 checkout, Nathan Aspinall needs just two darts to get it.

Treble 17, double 12 and we're all square after two legs.

Nathan Aspinall grew into the leg but left it too late, allowing Rob Cross to hit his favourite double 18 to hold relatively comfortably.

Rob Cross gets this one under way with 100 on his first visit.

Here come the players for the quarter-final number four - I don't envy them having to follow the last match!

The good news for them is that Nathan Aspinall's walk-on song is Mr Brightside by The Killers which immediately gets the crowd going.

Our last quarter-final of the evening sees 2018 world champ Rob Cross take on world number four Nathan Aspinall.

Cross has only gone out at the quarter-final stage once so far this Premier League season - and even that was after a deciding leg against Luke Littler.

However, he has only reached one final. That was in Exeter, where he fell to a 6-2 loss against Aspinall.

The Asp started slowly this campaign, losing in the quarters in the first three weeks before making the final in week four.

He lost to Michael van Gerwen on that occasion but went one better the following week.

After defeat by Littler in the last eight in Brighton last week, he'll be hoping to bounce back in Nottingham.

A match of ludicrous quality!

Michael van Gerwen averaged 110.94 but was blown out of the water by Luke Littler.

The teenager averaged 114 - that is just silly. Eight 180s as well for Littler. He will take some stopping in that form.

Nottingham was ready to explode!

Luke Littler comes so close to another nine-darter! He gets all the way to the double 12 - but just misses.

It's no bother, though. He settles with an 11-darter to storm into the last four.

Wherever he performs, the world is looking at him. This is not the norm, but he is making it his norm.

Obscene from Luke Littler!

He's hit seven - SEVEN - 180s in this match already and breaks yet again.

He's romping to victory.

Luke Littler hits tops for the first hold of the match...

But only after Michael van Gerwen came within millimetres of taking out 170.

Littler allowed himself a moment to breathe after that.

Good luck with dealing with this for decades to come - rather you than me.

This game is being played at a relentless pace with some outrageous scoring.

It's raining 180s in this leg before 17-year-old Luke Littler takes out 83 for a third break of the Michael van Gerwen throw.

There is no daylight, there is nothing between them.

A gift for Michael van Gerwen as Luke Littler misses three darts at double eight.

That allows MVG to come back and find double 10 to break again.

Luke Littler is back in front after a wayward dart from Michael van Gerwen costs him a look at a double.

The teenager comes back to hit tops edge ahead.
