Big defence from Hull KR as they rob the ball off Edwin Ipape.

Now the Robins will look to protect it better from this set.

Ryan Hall knocks on in his own half and Leigh are given cheap possession once again in a good position.

Can they punish Hull KR further before the break?

A third kick of the half from Ben Reynolds and Leigh's advantage doubles to four points.

This is a Challenge Cup final, the players work their socks off to get into this position and the referee makes that decision.

I'm not sure he led with the elbow. I think that is harsh.

And it is decided that Elliot Minchella is worthy of a yellow card and ten minutes in the sin bin.

The Hull KR loose forward is the first player to be sin-binned in a Challenge Cup final for 22 years.

A late shot from Elliot Minchella on Ben Reynolds as he kicks the ball away is penalised.

Hull KR let down by another piece of indiscipline.

What a lovely try that was. It's absolutely superbly executed to the nth degree.

The dummy pass is superb, the timing and angle of the pass to Lachlan Lam is too.

How many time have we seen the back rower burst through on the line? This time we've seen Lam do it too.

Brilliant from John Asiata in the build-up. The Leigh machine is working. They were clinical there.

Australian centre Tom Opacic gives the ball up coming out of a tackle.

Wow, that is sloppy and Leigh get a scrum when they had been under pressure.

The Robins are knocking on the door but they lose composure and give the ball away with a loose pass.

Both teams are playing risky rugby league. Mistakes, indiscipline, poor decision making - it feels like the last few minutes, not the first half!

They know the opportunity that is at stake.

I think they're very lucky there but Leigh aren't out of the woods yet as there's a set of six coming.

Leigh look a bit rusty with the ball and whoever can get on top of that sooner will be on the right side of the scoreboard.

There is a check for a possible penalty try.

Leigh wing Tom Briscoe loses the ball in the tackle and Tom Opacic kicks the ball towards the try line.

But is he stopped illegally from reaching the ball?

No he is not. But Hull KR have possession in a good position.

It has been a frantic and very enjoyable start to the game.

The only problem we are hearing that as many as 20,000 fans have arrived into the ground late due to awful traffic on the M1.

That is a real shame.

Brian Noble
Former Bradford coach on BBC Radio 5 Sports Extra

He found a way through and lifted his legs out of the tackles. He's right through the door and under the sticks.

Brilliant.

John Kear
Wales coach on BBC Two

That was sheer brute force and determination to shrug the defenders off.

The way he broke through, he had the composure. That is a great try.

Kevin Brown
Former England international half-back on BBC Radio 5 Sports Extra

The referee said it's a spear tackle. Does he take it past the horizontal? I don't think he does.

But the referee says it's an illegal tackle. I think it's a harsh call.
