They’ve been building nicely as we come to the end of the half.
Hull KR 4-6 Wigan
Merton: Wigan constantly cabbaging, slowing the ruck down… & not allowing Hull KR to get a quick play the ball - official needs to be stronger here.
Callum Thompson: I do think Ethan Ryan will definitely be KR's loss and another team's gain. So consistent in defence and attack.
Hull KR 4-6 Wigan
Amazing stuff from Shaun Kenny-Dowall who rolls back the years to intercept inside his own 10 and race upfield.
He's not got the legs to race in from distance but he's grounded just past halfway and suddenly Hull KR look alive.
But they fall just short of the line before the turnover.
Hull KR 4-6 Wigan
Wigan force an error of their own as Brad Schneider can't quite keep hold of the ball.
Great stuff from Wigan but can they prosper from their set of six?
Hull KR 4-6 Wigan
Kai Pearce-Paul knocks on well inside the Wigan half, immediately neutralising their attack.
Hull KR win the ball back and go on the charge in order to respond to Jai Field's score.

That’s what Jai Field offers.
He can go from 0-60 mph in a ridiculously short period of time.
He’s not the biggest but he flies.
He’s got the pedal down, he does that so often.

Commentator's curse as, shortly after I say the Cherry and Whites are short of answers, Jai Field prospers from a quickfire set of lateral passes as he dummies his way into sliding over at the corner.
Great stuff from the Wigan full-back. Harry Smith absolutely nails the kick and suddenly Wigan are in front.
Hull KR 4-0 Wigan
Brilliant stuff from Jez Litten and Shaun Kenny-Dowall to keep the ball alive amid plenty of pressure in the Wigan half.
Wigan, despite their pressure, are looking short of offensive answers right now, but with just four points in it, this game is still in the balance.

Both teams are in this battle now.
They’ve been weighing each other up and they have both felt their way into this game.
Hull KR 4-0 Wigan
Bevan French sends an absolute pearler of a kick from distance in towards the corner as Wigan charge.
Mikey Lewis picks the ball up under pressure from the onrushing Warriors but he twists and turns his way around and gains nearly 20 metres from their own in-goal area.
Stunning.
Hull KR 4-0 Wigan
Wigan win another set deep in the Hull KR half and Brad O'Neill almost twists and turns his way over but he's well held up.
A kick goes in on the turnover and KR's Ethan Ryan rises high to capture but spills the ball.
Referee Liam Moore decides, for whatever reason, not to penalise him for knocking on and they retain possession.
Hull KR 4-0 Wigan
What have Wigan got in response to Hull KR taking an early lead?
A quarter of an hour has passed and the Robins certainly look in better shape than they did in the early stages, but Wigan are finding it difficult to get anywhere near the line at the minute, as they kick from the turnover 40 metres out from their latest charge.

Easy as you like!
A bit too easy if I’m honest, it was just a bit of deception.
Louis Senior is in acres of space.
Liam Marshall has to come in and there’s no-one on the edge.

They know they have the game plan and will have opportunities from a scrum.
The fans really believe now!
Louis Senior

Hull KR celebrate as if they've scored a try. They now win a set of six deep in the Wigan half and they immediately prosper.
Louis Senior is teed up and he races in with plenty of space at the corner thanks to some stellar work from Mikey Lewis in the build-up. Game on!
Rowan Milnes misses the two, however.
Hull KR 0-0 Wigan
Harry Smith looks to race on to his own kick as Wigan keep the pressure on in the Hull KR half of the field.
He can't quite work onto it, but the momentum is certainly in Wigan's favour at the minute.
