The momentum really has swung, hasn’t it.
It's a really energised performance from Hull.

St Helens and England full-back
Darnell McIntosh take a bow!
To get up so high and force the error in the contest - and then it's really well picked-up by Andre Savelio.
Hull FC 12-8 St Helens
Bad news for both sides.
Mark Percival has failed his head injury assessment following that tackle from Hull's Brad Fash.
Meanwhile, Hull's Scott Taylor has gone straight to hospital with a suspected dislocated shoulder.
Andre Savelio, goal Liam Sutcliffe
Hull cross over - Andre Savelio touches down as Darnell McIntosh spills the ball after kicking laterally towards goal.
But referee Chris Kendall sends it upstairs after giving an on-field call of a try.
It's judged the ball travelled backwards before Savelio went over, and it's given!
Liam Sutcliffe kicks the extras and suddenly Hull lead St Helens by four.
Hull FC 6-8 St Helens
Jack Welsby kicks the ball dead under pressure and St Helens concede a goalline drop-out.
Hull win back the ball on halfway and Chris Satae races through and gains territory before the hosts also win another set of six.
Can Hull do anything with this decent patch? Surely another try is on the way.
Hull FC 6-8 St Helens
It's all Hull right now and St Helens look uncomfortable.
Can the hosts keep up this pressure?
Hull FC 6-8 St Helens
Tommy Makinson knocks on in the process of closing down Hull, who were on the break on the left just like they did a few minutes previously as Josh Griffin went over.
He grimaces, but he had no choice, the hosts were motoring through then.

Great credit to them and their coach because they've disrupted the Saints defence and when they got in position, the full-back has a show-and-go and Josh Griffin shows good support on the inside.
What a great riposte from Hull FC.
Josh Griffin, goal Liam Sutcliffe
Hull are off the mark!
Great try, this. Tex Hoy is sent through and races through the St Helens half and shrugs off Jonny Lomax to send Josh Griffin through.
That is a very well-worked try.
Liam Sutcliffe adds the two.
Hull FC 0-8 St Helens
Scott Taylor comes off worse in a tackle with St Helens try-scorer Joe Batchelor.
He's in bits as he walks off the field with what looks to be a shoulder injury.
A blow for Hull FC.

It’s heavy contact between the player and the ground and the defending player on top.
There’s not excessive force.
It’s a difficult one and sometimes referees feel forced to make a decision because a player got injured.
We've got to do everything we are doing to protect players but sometimes players are still going to get banged with nothing untoward going on.
Hull FC 0-8 St Helens
Iain Smith: Joe Batchelor has been a great signing for St Helens. Fab player. Good try.
Tommy Makinson
Tommy Makinson makes no mistake with the boot from that penalty.
St Helens lead by eight points and we've not even played 15 minutes.
Hull FC 0-6 St Helens
Referee Chris Kendall puts that Brad Fash incident on report, for contact with the head of Mark Percival, and then awards St Helens a penalty.
Fash is lucky not to be walking off the field, I reckon.
Mark Percival, unsurprisingly, comes off for a head injury assessment.
Hull FC 0-6 St Helens
Blimey.
Brad Fash goes down hard and lands on top of St Helens' Mark Percival in the process of bringing him down.
The replays look pretty grim. A woosy Percival eventually gets to his feet after some medical attention.
Boos ring around in the aftermath from the travelling St Helens support.

They hadn’t quite got it right before but that time it was absolutely on the money.
Fantastic line from Joe Batchelor!

Machine-like operation.
Really slick in their movements left to right and he couldn’t be stopped.
Joe Batchelor, goal Tommy Makinson
St Helens make their early pressure count!
Clinical stuff, this. A quick play-the-ball from Matty Lees eventually sees Jack Welsby tee up Joe Batchelor to run through a gap in the Hull FC defence to score the game's first try.
Tommy Makinson adds the two.
Hull FC 0-0 St Helens
Andrew Wood: Could we see a Hull derby in the semi? Good luck to all teams in the quarter-finals of the Challenge Cup.
Now that would add even more spice to things..! But Hull FC have a massive job on their hands here, first.
