Marc Sneyd - take a bow. What a 40-20 kick to put Hull in prime position.

John Kear on commentary says Marc Sneyd can shell peas with his left foot. Not sure if that's strictly true, but I wouldn't put it past him.

The first half was a competitive contest, full of strong defence, and the second is following the same pattern.

The high kick from Marc Sneyd almost does the trick again, but Wigan grab it at about the fourth attempt and somehow escape that spell of play without conceding any points.

Hull are pressing in the first few minutes of the second half. A penalty, then a repeat set.

They're cranking it up, but can they make it count?

Professional sports are often games of fine margins, and Sam Powell discovers that the hard way.

The Wigan hooker's kick lands out on the full only by a couple of inches, and the Warriors are forced back a good 30 metres as they prepare to defend a set of six early in the second half.

For all the hard tackling and good running in the sunshine at Wembley, the key moments of this highly competitive, energy-sapping contest have so far been about kicks.

Wigan's opening try came from a speculative Thomas Leuluai bomb which bounced horribly for the Hull defence. Then Marc Sneyd twice opened up Wigan with high balls, both of which they failed to deal with.

A superb piece of handling then got Wigan back on level terms on the try front. But George Williams, for all his skills with ball in hand, is not the reliable kicker that some teams have. His missed conversion of Oliver Gildart's try is the margin of Hull's lead at half-time.

Will that still prove an even bigger factor come a quarter to five?

Our BBC One coverage is showing an animated Shaun Wane trying to get his message across to his Wigan team.

It looks a lot more relaxed from Lee Radford in the Hull dressing room.

What was it like on the pitch for the players? Captains Sean O'Loughlin and Gareth Ellis weigh in with their thoughts.

Wigan's O'Loughlin: "Very tough. We had to try and get used to the pace of this game. Energy levels have dropped towards the end but I think both sides will be pretty pleased with that first half."

Hull's Ellis: "The disappointing thing from our point of view is not getting to the end of our sets. Most of the game has been played on our try line so we need to switch it to the other end of the field."

While we've got a short respite from the action at Wembley, here's what our friends at BBC Get Inspired have been up to...

Marcus: Great first half with both teams showing how much they want it.

Chris: Missed kick after the try could come back to haunt Wigan.

A couple of close things in the final seconds of the first half, but the hooter goes with no further trouble to the scorers.

Only two points separate the sides at the halfway point of this Challenge Cup final.

On balance, Hull probably deserve to be just in front.

Trivia fans - did you know Wigan centre Oliver Gildart's father, Ian, was on a Challenge Cup-winning Wigan side in 1990?

Speaking to BBC Sport before kick-off, Gildart said: "He just told me enjoy it. There's only so many times you get to go to Wembley in your career so just take it all in. I don't know where my family will be sat but I want to get the win for my family today."

Gildart has a Wembley try to celebrate, but you imagine it'll mean a whole lot more if Wigan come away with a win.

They've changed their tactics and it's worked. Instead of hitting Sam Tomkins, they hit Oliver Gildart. Very clever play from Wigan.

Hull in front on the board and probably just about deservedly so.

While Marc Sneyd's kicking has produced two scores for Hull, a kick is only as good as the chase and that has been excellent from the Airlie Birds.

One thing you notice is the huge expanse that is the pitch here. That possibly could take its toll on that big Hull pack but they've managed that well thus far and it is still looking fresh.

I really like Sam Powell, who is a real live wire around the ruck and I think his introduction can really give Wigan a boost.

Just a word on the crowd - possibly down on recent years, but still a buzzing atmosphere.

How on earth have Hull FC survived that?!

A couple of repeat sets for Wigan weren't made the most of. Sam Tomkins lunged towards the line but was just short and lost control of the ball, under pressure from two Hull defenders.

There's a melee afterwards, which will take some sorting out.

What a passage of play that is!

Wigan attack and Josh Griffin again intercepts - this time Joe Burgess takes the free play and gets within a couple of metres of the Hull try line!

Hull then give away a penalty and Wigan will have a fresh set of six from close range.
