It's up to Castleford now to grab this game by the scruff of the neck, get the confidence going, get the scoreboard going.
Wigan 22-0 Castleford
The video referee is required again to determine whether Denny Solomona has got over the line for Castleford.
His knee was in touch as he grounded the ball, and the Tigers remain without any points in this Challenge Cup quarter-final.

Opportunities for both sides early in the second period, created by breaks from deep, but neither can cross the whitewash.

Quote MessageWe've got to keep hold of the ball. We're good enough to break them down, they've been really good with their scrambling. The more we're down there, we'll score some points and make a good crack at it.

HT: Wigan 22-0 Castleford
Quote MessageWe've been the best team. Castleford are a good side and when we played them a few weeks ago, they came back well in the second half. So when we come back out onto the field we're coming back with a 0-0 mentality.
Sam Tomkins, Wigan full-back on BBC Two
Wigan 22-0 Castleford
Wigan's clinical finishing has been the difference here.
One try for Dan Sarginson, one for Sam Tomkins, two for Josh Charnley. Wigan in control.
Castleford have had their fair share of territory, but haven't found a way past the Warriors' defence. Much work to do for the Tigers.
Wigan 22-0 Castleford
Castleford have to score next, ideally before half-time, if they're to have any realistic chance of winning this quarter-final.
Wigan 22-0 Castleford
Quote MessageIt probably took five or six seconds to switch from one corner to the other. Most teams wouldn't be able to defend that, it's that crisp, that swift. It's very, very hard to defend.
Kevin Brown, Widnes captain on BBC Radio 5 live sports extra
Josh Charnley
Two tries in five minutes for winger Josh Charnley and Wigan are moving into an unassailable lead.
Charnley dives in at the corner and the video referee confirms he grounded the ball.
That's 158 tries in 161 Wigan games for Charnley. Prolific.
Wigan 18-0 Castleford
Quote MessageThe difference at the moment is the try-line defence. Great break, and he's away. It's all about being clinical and Wigan have been very, very clinical so far.
Jonathan Davies, Former Wales & Great Britain international on BBC Two
Josh Charnley, goal Matty Smith
Wigan have a third try without reply inside 29 minutes.
It's created by a superb initial break by Taulima Tautai, and when the ball breaks to the left wing, Josh Charnley dives over from close range.
Matty Smith nails the kick from the touchline. Any way back for Castleford, who now trail 18-0?

Wigan 12-0 Castleford
Defensively, Wigan have been awesome so far.
Castleford are trying their best to find a way through - and you would fancy them to at some stage, given the creative talent they have in attack - but as yet they haven't scored any points.
Wigan 12-0 Castleford
Castleford are almost in down the left side but Denny Solomona is denied by a superb tackle by Sam Tomkins. The video referee makes sure.
The Tigers have a penalty though, as Dom Manfredi is deemed to have made a high tackle on Luke Dorn.
Wigan 12-0 Castleford
Joel Tomkins is on the pitch for Wigan to make his 200th appearance for the Warriors.
He's in his second spell with the club, having taken a break from rugby league to play rugby union for Saracens and England.
