Newly-promoted Castleford suffered a harsh reminder of the realities of Super League as they fell to defeat against an impressive Hull.
Castleford (6) 18
Tries: Viane (2), Fa'aoso, McGoldrick
Hull (18) 42
Tries: Domic, Briscoe, Cooke, Blacklock, Raynor, Yeaman (2), Lupton
Goals: Brough (3), Cooke (2)
Tries from Sid Domic, Shaun Briscoe and Paul Cooke gave Hull a commanding 18-6 half-time lead, although a late score from Gray Viane gave the Tigers hope.
Hull pulled clear after the break with tries for Nathan Blacklock, Kirk Yeaman (2) Gareth Raynor and Peter Lupton.
Cas showed some encouraging touches to score three second-half tries.
The home side came out all guns blazing, but found discipline a problem early on as they conceded a string of needless penalties to put themselves under pressure and Danny Brough kicked Hull into the lead.
Paul King's skilful pass then created the overlap for Domic to skate over for his first Hull try.
Richard Fletcher's penalty cut the gap, but soon after a brilliant pass from Jamie Thackray allowed Richard Horne to sprint clear and two tackles later Briscoe burst over.
Cooke's try made it 18-2 to Hull, but Viane's late score - following a precise Danny Sculthorpe chip early in the tackle count - cut the arrears.
Castleford started the second half well, but could not make their territorial dominance show on the scoreboard as some panicked decisions deep in Hull territory with the try-line beckoning.
Hull then showed some clinical finishing to effectively wrap up the match with two tries in two minutes from wingers Blacklock and Raynor.
Viane's second try, after Ryan McGoldrick's kick, brought the score back to 26-10, but Hull's superior fitness started to tell as they went over twice through Yeaman and then again through Lupton.
Late tries from Richard Fa'aoso and McGoldrick added some respectability to the score, but Castleford were a well-beaten side.
Castleford coach Terry Matterson:
"I'm a bit disappointed, definitely - not with the effort but we were pretty poor with the ball.
"I was expecting a better result, a closer result. I thought at times we looked like getting on top but we just couldn't get over the line.
"It's going to take a while but we're going to get better."
Hull coach John Kear:
"I think there were some good signs for Castleford.
"They certainly don't look as far off the pace as Leigh (last season's promoted club) did this time last year.
"Obviously they are going to get better. They had 10 new guys and that is a lot of people to integrate into their team."
