Castleford head coach Ryan Carr told BBC Radio 5 Live:
“It was unbelievable and something I knew was here in the group.
“We just had to keep going after it and not let outside noise dictate how we felt and played. We’ve stayed on course from day one and we’re going to keep staying on course.
“We’ll have bumps and bruises along the way but if we can continue to put more performances like that out there, we’ll be better as a club.
“Defensively, I was really impressed. We worked hard on that through the week because we know they’re a potent attacking team, so to keep them to a low score is something I’m more pleased about than the points we scored.”
St Helens head coach Paul Rowley told BBC Radio 5 Live:
“We were double figures in errors and double figures in penalties against – that’s not compatible to winning performances.
“Those two factors contribute to fatigue, then you lose the physicality as well and it doesn’t give you a chance to regain momentum.
“Cas had the momentum for pretty much all of that game, to be honest.
“It was remarkable to go in at half-time within touching distance. That gave us an opportunity if we scored first, but the trend of giving away cheap possession and unforced errors continued.
“We came out with belief and enthusiasm, but credit to Castleford, they continued what they did in the first half and unfortunately we copied and pasted as well with the errors and the penalties.”
