It is safe to say it was doubles that won that game.

Rob Cross averaged 92.65 and Luke Littler 92.76 so there's only a tiny, tiny amount in that.

Cross was six from 20 on the doubles, which is far from perfect, but Littler was down at three from 18.

Littler's finishing has been a bit awry in the past few weeks.

A really scrappy leg to seal Rob Cross' progression to the final.

He misses six match darts before finding double two to wrap up a 6-3 win.

Luke Littler missed three darts at double in the midst of that to secure the leg and keep the game going.

Cross reaches his first Premier League nightly final of the season. The wait goes on for Littler.

He gets another chance, but misses two darts at double two.

Cross returns to take out 12 and open up a two-leg lead.

There is pressure on the throw consistently at the moment.

Almost a 164 from Luke Littler this time. He again finds the successive treble 19s but finds outer bull instead.

He's left with 25 and it ends up being a bit tricky. He goes five, double 10, but goes on the inside again.

He manages to squeeze the final dart past the single five for the double and the leg.

We're still on throw. Littler needs a break.

Oh! So close from Luke Littler to the 146 checkout. He finds the successive treble 19s but is just on the outside of double 16.

Rob Cross doesn't give him another opportunity though, taking out 100 to lead again.

Some way off the level they found in the quarter-finals but it does not matter - just win the game.

Luke Littler gets himself down to 85 and leaves double tops but he goes under.

Rob Cross isn't on a finish though so he can't be punished.

The double 10 attempt also goes inside from Littler but he finds double five with his final dart to move level.

What on earth has happened there!?! Luke Littler goes for the treble 20 but a deflection helps it into treble 18 instead. There's a perplexed look on the teenager's face. He'll take it.

It leaves him with 52 and he lands double 10 for the break. We're back on throw.

Luke Littler just hasn't got going.

Rob Cross gets himself down to 93 and hits treble 19 and then his favoured double 18 for an 11-dart break.

Voltage is charging ahead.

A hold for Rob Cross.

He misses four darts at doubles and that gives Luke Littler a chance at 170.

He can't do it, though, and Cross finds double eight for the leg.

Rob Cross, who threw his highest Premier League average in the quarter-finals, has the throw.

Game on.

Luke Littler and Rob Cross have faced each other twice in recent weeks.

The teenager won 6-2 in the World Championship semi-finals, before claiming a 6-5 quarter-final win on night two of the Premier League in Berlin.

Will it be third time lucky for Cross?

Great sign being held by a couple of youngsters in the crowd in Exeter...

I know it gets mentioned a lot but you watch Luke Littler play with such composure and you forget he's only 17.

Ed O'Toole: Cross vs Littler should be the final tonight. Sadly it’s a semi but one would think that whoever out of them that reaches the final will win it.

Who will face Nathan Aspinall in the final? It'll either be Rob Cross or Luke Littler.

Cross was in imperious form in a 6-1 demolition of Gerwyn Price in his quarter-final, while Littler was just as impressive in his 6-2 win over Michael Smith.

In the end, which seemed extremely unlikely at 5-1 down, Luke Humphries averaged more than Nathan Aspinall in that match. Cool Hand Luke averaged 103.35 to The Asp's 97.39.

Aspinall took out six of his 10 checkouts, compared to five from 12 for Humphries.

What a match!

This is brilliant composure from Nathan Aspinall. From 5-1 up to be pegged back to 5-5 must be destroying but he remained calm.

He knew he had the darts and that often proves so pivotal.

He leaves 160, and Luke Humphries is waiting in the wings with 167 remaining.

It is superb from Aspinall, hitting successive treble 20s, before a little manoeuvre on the oche to find double tops for the match.

He's through to successive nightly finals. Will he go one step further this week?

We're going to a deciding leg, folks.

Luke Humphries is left with an awkward double 19 to check out.

He goes inside, so finds three, and double eight to send us level.

Nathan Aspinall has the throw in the last leg, but Humphries has won four legs on the spin.

Wow! This game has turned so quickly.

Another 11-dart leg for Luke Humphries as he takes out double 18.

Remember, Nathan Aspinall missed match dart at bullseye.
