The on-field call decided that.
St Helens 8-19 Warrington
Matty Ashton had nowhere to go out on the left edge, so kicks through to himself.
Replays show that he touched the ball with his hand when he tried to prod it on again before touching down.
St Helens 8-19 Warrington
Matty Ashton may just have come up with another dazzling effort for his highlight reel.
Wrench (con Thewlis)
It's great vision from George Williams to create this one.
The Warrington captain chips his kick from left to right, it evades everyone before Connor Wrench swoops in to finish near the posts.
We have yet another try review. The call on the field is that this one will count from Connor Wrench.
St Helens 8-13 Warrington
Lachlan Fitzgibbon so nearly has another try for Warrington.
We need a video replay to check if this one counts, but Fitzgibbon loses the ball as he crosses the line under a pile of St Helens bodies.

Another St Helens error close to their line has Warrington lining up for a third try now.

They can't stop playing now, Warrington. There's plenty of time in this game. They've got to assess and make a better kick on the last tackle.
Saints will come back.

There's two things, the foot race to the corner, but the finish itself, he knew exactly what he was doing.
It is brilliant, super, I don't know what, words fail me.
Matty Ashton (Thewlis con)
Yes they do!
Matty Ashton zips beyond the clutches of Tommy Makinson on the left, then beats a last desperate tackle on the line with a stunning diving finish into the corner.
Ashton didn't have any space to spare with his effort to get the ball down as he was clattered into touch while in full flight.
Josh Thewlis is on target with his conversion.
Do Warrington have the lead again?
St Helens 8-7 Warrington
Jonny Lomax has had a nightmare from the resulting restart.
The kick appears to be going out on the full, but the Saints captain catches it with his foot in touch.
Jon Bennison
Jon Bennison makes no mistake and edges St Helens back into the lead.
St Helens 6-7 Warrington
Daryl Clark forces a clever penalty for St Helens.
His quick thinking to run at Toby King leads to an offside call from referee Jack Smith.
And St Helens will kick to try restore their lead...
St Helens 6-7 Warrington
Konrad Hurrell and Alex Walmsley try steam roll their way through Warrington's resistance.
Their efforts have them a metre out, but James Bell is eventually stopped as he tries to dart over.
St Helens 6-7 Warrington
It's chaos with Warrington attacking St Helens' try line now.
Passes are thrown recklessly by the visitors, and their lack of composure lands the ball in the hands of St Helens' Morgan Knowles.
The hosts breathe a sigh of relief.
St Helens 6-7 Warrington
Toby King comes up with a huge intercept for Warrington and the Wolves chew up the metres with St Helens now back-peddling in defence.
St Helens 6-7 Warrington
A great kick and chase for St Helens has Matt Dufty under pressure under a high ball.
Seems we are going to be treated to more end-to-end attacking cup action.

There's gonna be some tired legs in the last 20 of this game because they've given everything so far.
That's where the opportunities will come.
