On and on we go!

Jonny Clayton hits double eight, the crowd at Winter Gardens roar - and from the brink of victory, James Wade might just be getting a little nervous.

No one expected this at 16-10.

Surely not...

Jonny Clayton breaks again after James Wade is unable to get the 100 checkout.

The crowd are suddenly starting to believe. Clayton has the darts to reduce the gap to two legs and he might just be starting to belief.

That's two. Four more to go.

Clinical finishing from Jonny Clayton and he keeps this match going a little longer.

Tops for the 102 out and another hold.

Six legs in a row needed for Jonny Clayton - and that's just to take it to extra legs.

Big ask but there's one of them. A rare off leg for James Wade and Clayton nips in for a 15-dart break of throw.

James Wade is closing in on a seventh World Matchplay final.

Jonny Clayton fails to finish out a leg he looked to have wrapped up. Just 50 needed but two misses at double 16 and he's done.

Double top for Wade... he misses it. And double 10. But gets the double five to move to within a leg of victory.

That is a superb adjustment. He is just two legs away from the final and he is feeling it.

James Wade is two legs away now.

Double 12 is hit at the second attempt and that secures a 12-darter.

Is there any way back for Jonny Clayton? It doesn't feel like it now.

Oh dear, oh dear. Jonny Clayton undoes his fine work in the previous leg.

He was cruising in the leg, down to 129 with James Wade nowhere.

But suddenly he only gets 61, Wade gets 145 and is ready to pounce.

A miss at double 16 from 'The Ferret' and Wade comes in to hit tops.

That could be a huge moment. You feel he has to back it up with a hold of his own.

This one isn't over just yet...

A rare chance on the James Wade throw for Jonny Clayton... and this time he takes it!

Left with a 120 finish, he misses the treble 20 with his first dart but gets it second one.

One shot at tops - and that's all he needs. Hold and suddenly the gap is just two legs.

The holds keep on coming!

Time is running out for Jonny Clayton but he is hanging in there.

'The Ferret' holds again with another 14-darter.

He gets a 180 and makes no mistake on the outer ring. It's vital he keeps holding but he needs to show a bit more of that on the James Wade throw or this game is over...

An eighth straight hold of throw for James Wade.

There were a couple of chances for Jonny Clayton in the first couple of those but not in the last few.

Clinical from Wade. Another 180 in the leg and just one dart needed for tops.

It's a really incredible display from James Wade. He is playing to his top level here.

James Wade is still averaging 105. If he keeps himself there, a spot in tomorrow's final is surely his.

It's all Wade. Can Jonny Clayton turn the tide by the seaside?

Straightforward hold for Jonny Clayton.

Double 16, a 14-darter but is it too late for the Welshman?

James Wade needs just five more legs to reach the final.

This was Jonny Clayton around 45 minutes ago.

A thumbs up, all smiles.

There hasn't been too much to smile about since.

James Wade is edging ever closer to another World Matchplay final.

He can't quite belief a dart at double six for a 126 out is just the wrong side of the wire but it doesn't matter.

The 42-year-old is back and finds double two for a 14-darter.
