"Hull FC have been as poor in attack this evening as I have seen them this season."
In stark contrast, with Gareth Ellis in the stands, Hull FC look somewhat rudderless. Steve Michaels is held up over the line for the home side but from the next play Jordan Thompson ploughs forward into heavy traffic - on the last tackle. Not his or Hull FC's finest moment.
Warrington lose Ben Westwood to the sin-bin for conceding three penalties in three tackles.
And Widnes make the most of their numerical advantage when Kevin Brown dances through the defence to score, with Jack Owens' goal giving the Vikings a 20-point lead.
Josh Mantellato curls in a lovely effort to put Hull KR three scores clear - and it's no less than they deserve. It was noticeable the way Terry Campese took control of the situation, instantly calling for the two points when the penalty was awarded - a cool head in a pressurised environment.
That's what derby victories are built on - superb, full-hearted runs like the one Kris Welham has just produced from deep, powering past three tackles before winning the penalty as he's cynically held down as the pitch began to open up.
That's 20 unanswered points for Widnes now as Lloyd White goes over from dummy-half and Jack Owens adds the conversion from the touchline.
The two full-backs have had decent games but in the space of two minutes both Kieran Dixon and Jamie Shaul both fail to cover themselves in glory as high balls are allowed to bounce or kicked forward after being misfielded. But both players get away without being punished - maybe they've earned that luck for their displays thus far.
Hull FC defend with real passion to keep Hull KR out, but it's almost calamity at the handover as disorganisation at the play-the-ball sees players with their backs to play wandering back into position as the game restarts around them. Hull FC need their senior players to take control.
Catalans have a sixth try and Damian Cardace has his second after receiving a fantastic miss-out pass from Scott Dureau who, for once, can't add the conversion. Must be the commentator's curse.
Terry Campese is having a fine game at stand-off for Hull KR and his perfectly-weighted kick turns Jamie Shaul around and gives the full-back nowhere to go before he's engulfed by Robins defenders before he gets back into the field of play. Goal-line drop-out and all thanks to Campese's beautiful kick.
That was close. Albert Kelly shows great skill to pluck a kick out of the air in attack and in the shadow of the posts tries to slip the offload away only to nudge it forward - if that ball had gone backwards it was a try under the posts for Hull KR.
Very good start to the half for Hull FC as they win a penalty for an obstruction by Hull KR after a bomb goes up. They go close with Joe Westerman held up over the line but the Robins defence holds firm.
Hull KR put boot to ball and we're off. Which way will this go?
Wakefield begin the second half as they finished the first - conceding points.
Scott Dureau, who has been pivotal, puts the kick in behind and Damian Cardace reacts first to touch down. It's no surprise that Dureau remains perfect with the boot.

"Hull KR do seem to struggle to keep possession but they are devastating with ball in hand.
"It is a big ask for Hull FC because they have looked predictable. They have got 12 points in them but Rovers have probably got more than 12 points in them."
Right on the hooter Jack Owens has another chance from the tee after Warrington concede a penalty. Not for the first time, his effort is off target and Widnes only lead by eight points after the break despite outscoring the Wolves three tries to one.
Hull FC, who have lost Liam Watts to injury for the time being, have had plenty of possession but you have to say for the most part the black-and-whites have struggled to really put their opponents under enough pressure.
In contrast, Hull KR look vibrant in attack - but will they regret not getting further ahead of the bitter local rivals while being on top?
Still playing at Widnes, who extend their lead with a brilliant third try.
Fabulous pass from Rhys Hanbury to Stefan Marsh who touches down for his second try of the evening. The Vikings can't get full value for their score, though, as Jack Owens conversion attempt is off target.
Kieran Dixon - the star of the first half - is held in possession in his own half as the hooter goes for the half-time interval. Plenty to chew on after that 40 minutes - and plenty to be said in both changing rooms.
Not sure the half-time oranges will taste too sweet in the Wakefield dressing room. Tries from Benjamin Garcia, Willie Tonga, Ben Pomeroy and Elliott Whitehead have Catalans in complete control.
