What do YOU think is the premier derby in rugby league?

Here are a few suggestions:

• Workington v Whitehaven
• St Helens v Wigan
• Batley v Dewsbury
• South Sydney v Easts (Sydney Roosters)
• Manly v Parramatta
• Castleford v Featherstone

Castleford edged a real see-saw battle with Leeds Rhinos at the Jungle last night, running out 18-14 winners with a late score from Jake Webster.

It was one of two tries for the former Hull KR centre, who was joined on the scoreboard by ex-Hull FC prop Andy Lynch.

Luke Gale added the extras to all three of those scores, which proved crucial when Leeds half-back Liam Sutcliffe failed to convert two of his side's three scores.

Well, that first 40 has produced an interesting scoreline... were you expecting that?

It's not the only action we're bringing you this afternoon either.

We've got live text and radio coverage of St Helens v Wigan later. Kick-off in that one is 15:15 GMT.

Rovers try to run it with the clock over and the hooter gone but the ball goes loose.

It's been frantic, scrappy, ferocious but Rovers have come up with the moments of quality.

Ryan Shaw and Ken Sio scored the tries, which Josh Mantellato has added four points with the boot.

Lee Radford needs his side to find some rhythm and a platform - the direct, physical approach hasn't paid off yet.

Well it was always going to flare up at some stage.

John Boudebza started it after a shoulder charge from Josh Bowden. Everyone came flying in.

Nothing too serious, but a little bubble over of the Hull derby cauldron there. Penalty Rovers. Hooter has gone...

Josh Mantellato compounds Hull FC's glut of penalties conceded with another two points for Rovers.

It's a two converted score lead.

Hull FC make an error in their flow to gift possession back to Rovers with a scrum. Story of their half.

We've got fewer than four minutes to play before the break.

Danny Houghton pinged, Rovers might be going for goal here.... no it's a tap and another penalty!

Hull KR have found their rhythm now, mixing up out the back, at the line and flat passes to work the Hull defence.

Albert Kelly is probing, Ben Cockayne chiming in and in John Boudebza they have one of the smartest hookers around.

Hull need something before half-time because they are not in this game right now.

Hull KR have gone back to basics. Gone are the bustling shifts to the wings. It's smart, position-focused footy and it paid off there with the Hull FC error.

Another penalty goes Rovers way as we move into the last 10 of the half.

Hull FC think they're on the board... but Danny Washbrook knocks on in the process of scoring.

James Child is the man in the video referee booth and says no try.

Marc Sneyd's kick was teasing though, that might be the route to a score for the visitors.

Just wondering whether the last few penalties have given Hull a bit of momentum in this game.

Might have done, but Hull have spilled the ball in the Rovers 20. Scrum head and feed to the home side.

Potentially another let-off.

Maurice Blair got a bit mixed up on the last and has to hurry his kick away.

Rovers are finding themselves under the cosh at the moment.

Hull FC looking to bring the ball away from their own end but the red and white wall currently holds firm.

First quarter gone and this has been raw power rather than finesse.

James Green left on the deck by a thumping hit by Scott Taylor. Unusual technique.

Hull FC's prop pairing of Taylor and Liam Watts both played for Rovers. No sentiment at the moment. They've blasted in.

Clock is off, looks like another concussion assessment is coming. Quite right too. It's safety first.

Another six... Hull continue to hammer away but the move comes to an end when the usually impeccable Danny Houghton makes an error and the visitors knock-on.

Pressure relieved on Hull KR.

Hull finish off an excellent attacking set by forcing a goal-line drop out.

They bashed away at the Rovers line and a Marc Sneyd kick saw the covering Ken Sio pinned in-goal.

They get the ball back from the drop out and keep up the pressure...

Rovers cough up a penalty, too long in the tackle and FC get repeat sets.

They're up to the 20...
