Warrington 22-16 St Helens
St Helens aren't done yet.
Mark Percival takes some tackling out on the right for the visitors.
The ball is spun back in field, and a high kick is sent up.
While Matt Dufty was caught out a few times in the first half by those high bombs, he takes this without any drama.

I said the next mistake would be crucial, it was St Helens.
An absolute disaster for St Helens there, they gifted them that try, they are self-destructive.
They're not respecting the ball, he tried to be a bit clever'
Matty Ashton, goal Thewlis
Matty Ashton puts Warrington ahead again!
It's a try that has come from a St Helens error.
A tired looking pass deep in their own defensive half is allowed to bounce.
A Warrington hand gets to it first, and from the flick back it's passed on to Matty Ashton who crosses untouched to edge the hosts back in front.
Josh Thewlis adds the two points from the tee to open up a six-point Warrington lead.
Warrington 16-16 St Helens
For a fraction of a second, Matty Ashton looks like he is about to race away for a Warrington try.
He steps beyond one tackle, but just as he is about to gather some real pace Daryl Clark comes in with a wonderful cover tackle.
It might be a bit much to call it a try-saving effort, but I'm not sure who would have stopped Ashton if not for Clark.

Less than 20 minutes remain, and Tommy Makinson shows how Saints still have to give in this game.

Robbie Hunter-Paul
Former New Zealand international on BBC Two
He's a master of making the right decision.
George Williams is the man for Warrington to unlock this game, we said they needed to find a way to break the St Helens momentum, they've found another way with this try.
Toby King, goal Thewlis
And punished, it is!
England captain George Williams is again the architect of this try.
He drifts left with his run, then picks Toby King out with a short cut-out pass that sends the winger cruising over.
Josh Thewlis converts, and it's all square at the Halliwell Jones Stadium again.
