The Black and Whites scored 28 unanswered points in the second half of the 205th meeting between the two to put an end to the Robins' winning run that had stood at three matches.

A total of eight tries, seven of which were scored by graduates of the club's academy, proved enough to earn Agar his first derby win as a coach and set his side up for their clash against Wakefield in seven days' time.

"We've trained with a good attitude and practised really well," he said. "I thought at half-time that when we'd done something good we followed it up with something bad. It was a little bit tit-for-tat.

"But we felt that if we ironed that out that we could win the game and win well. We cut out the errors and took our chances. I thought that Matt Sing's try was a catalyst for us and that once we got the lead we really thrived and buzzed off it."

Wakefield coach John Kear admitted he must rally his faltering side ahead of their semi-final against Hull after Sunday's 24-10 reverse at Bradford condemned them to a fourth straight defeat.

Wakefield established a 6-0 lead through Damien Blanch's second-minute touchdown and a penalty from Brad Drew, but they were simply overpowered after the break as Bradford claimed four tries through Paul Deacon, Terry Newton, Ben Jeffries and Iestyn Harris to render Blanch's second try in the closing stages meaningless.

"Hull will be buoyant after beating us last week and then beating Hull KR, but it's my job to turn things round," said Kear.

Castleford coach Terry Matterson was a happy man after the Tigers ran in 13 tries in a 66-12 demolition of Harlequins at the Stoop.

The Castleford backs feasted on some woeful defence as Richard Owen, Luke Dorn and Michael Shenton all claimed hat-tricks.

Further Tigers tries came from Stuart Donlan, Ned Catic, Ryan McGoldrick and Michael Wainwright as the visitors went in at the break 28-12 up and then stretched away after the interval.

Featherstone snatched a 30-30 draw against Co-operative National League One title-chasers Salford with a last-minute penalty goal by skipper Stuart Dickens.

Halifax kept up the pressure at the top by staging an impressive fightback to claim a 26-26 draw with Widnes at The Shay.

Ian Watson kicked a winning penalty with just two minutes remaining to snatch a dramatic 18-17 victory for Leigh over Batley.

Rock-bottom Dewsbury Rams produced an excellent second-half fightback but it was not enough to prevent a 36-32 defeat at home to Sheffield Eagles.
