The St Helens fans rise as one to acclaim Luke Thompson as he takes a well-earned breather and goes on a little warm-down along the touchline. The big prop has been immense.
St Helens 22-6 Salford
Salford just haven't been able to find that intensity in this second half that they found in the final 10 minutes of the first.
The body language of the Red Devils players tells you that they know the game is up. But what a season they have had.

The clock is stopped while St Helens prop Luke Thompson is treated for a spot of cramp.
He's put in quite a shift over the course of the play-offs for Justin Holbrook's side.
He's played the whole game so far but finally goes off for an interchange.
Lachlan Coote
Lachlan Coote's angled kick hammers another nail into the Salford coffin.
The crowd of 64,102 are going to be watching St Helens lift the Super League trophy in the next 20 minutes or so.
St Helens 20-6 Salford
Image source, Rex FeaturesYou get the impression that St Helens are holding Salford at arm's length now, even when Niall Evalds threatens to make a break.
But when the ball is turned over Saints march the ball downfield and earn a penalty.
They will run more time off the clock and go for the posts.
St Helens 20-6 Salford
We're entering the closing stages and Salford have a mountain to climb.
Saints run more precious seconds off the clock as they move the ball deep into Salford territory.
The Red Devils get it back under their own posts.

They have just been relentless with the pressure that they have put on Salford and they have cracked two or three times, which is why Saints are in this position.
St Helens 20-6 Salford
Oh no! Salford have the ball only a couple of metres from the line and Gil Dudson knocks on at the play-the-ball.
Was that Salford's last chance?
St Helens 20-6 Salford
Oh hello! Salford's Joey Lussick goes for a 40-20 from deep inside his own half and pulls it off.
The Red Devils will have a set inside Saints' 20m line.

Image source, Rex FeaturesThe St Helens supporters have got gradually louder as the second half has gone on, their side edging closer to a first Super League title win since 2014.
The flags given to fans in the front few rows in the Saints end are being flown more regularly now.
Lachlan Coote
The ball is just over 20m out and bang in front of the posts, and Lachlan Coote makes no mistake.
Salford must now score three times to get back into this. It looks a long way back.

Saints prop Luke Thompson is brought down by a high tackle by Gil Dudson.
St Helens will have a kickable penalty and will go for the sticks.
St Helens 18-6 Salford
St Helens have picked up the tempo again and Kevin Naiqama crashes into Niall Evalds near the Salford line.
The Red Devils then hand over possession again with an error and Saints have a set deep in opposition territory.

Kevin Brown

Image source, Rex FeaturesMarks Percival has been doing that all his career, he changes the angle across the field a lot and he found a great touch at high speed which is so hard to do.
The context of the game has completely changed, Saints have got that 12-point lead again and I feel if they score next then it's game over.
St Helens 18-6 Salford
Krisnan Inu coughs up the ball as Kevin Naiqama collided with him.
That looked like a shoulder charge to me, which would be a penalty to Salford.
But to add insult to injury, referee Chris Kendall awards St Helens the put-in at the scrum inside the Red Devils' half.
Another score now could settle this game.
St Helens 18-6 Salford
They may be 12 points behind but the Salford fans have not given up on this yet.
The supporters behind the posts Salford are attacking raise their voices again to encourage their side.

Mark Percival - take a bow, son. The judgement on that grubber kick was dreamy. His roar, and that of the St Helens fans, tells you how important that score is.
Mark Percival, con Lachlan Coote
Image source, Rex FeaturesThe try is given, and never really looked in doubt.
On the last tackle Mark Percival darts across the Salford defensive line before racing on to his own perfectly-weighted grubber kick to touch down under the posts.
Lachlan Coote slots over the simplest of conversions.
St Helens 12-6 Salford
St Helens think they're in again here. This is a big moment.

St Helens have so far been unable to recapture the tempo with which they started the first half.
Are nerves beginning to play a part?
