Castleford coach Daryl Powell and captain Michael Shenton said they were proud of their tough showing against Wakefield.
Castleford were 7-0 up at half time thanks to a try from Mike McMeeken and a drop-goal from Luke Gale.
Ben Jones-Bishop scored for Wakefield in the second half but Gale then added two further penalty goals to seal an 11-6 victory over arch rivals Wakefield at the Mobile Rocket Stadium on Thursday night.
Speaking after the game, Powell said: “Summer rugby is awesome, isn’t it?
“I thought our boys were awesome and Wakefield were tough as well. We just had to tough it out and the boys were great.
“It is very difficult getting your attacking game together in these conditions. You just have to get what you can and it was tough, but I’m really pleased.
“It is a big win for us. It is hard to go there (Wakefield) when they are playing well and win. We had a tight game there last year and this was another one.”
Castleford kept Wakefield scoreless in the first half and only conceded one try in the second period.
And Tigers captain Michael Shenton said he was proud of their solid defence.
He added: “We kept turning up for each other and I’m proud of our defending.
“Before the game, we spoke about playing tough because we know Wakefield like to play a lot with the ball and they are a dangerous team, so we’re really pleased with the win.
“We couldn’t seem to get to a kick on-field in the first half so we just had to keep riding the penalties and keep turning up for each other. We made some smart decisions.
“It was a really pleasing win and a great start to Easter for us.”
