Castleford did not look back from Zak Hardaker's first-half brace of tries as the Tigers all but secured the League Leaders' Shield with a 23-4 victory over Salford Red Devils.
Hardaker went over underneath the posts in the seventh minute and the full-back touched down again after 26 minutes following some neat footwork past the Salford defence.
Luke Gale converted both scores to give the Betfred Super League leaders a 12-0 cushion at the interval, a lead that was reduced three minutes after the re-start when Manu Vatuvei grounded Todd Carney's grubber kick.
What a performance by the Lads! Outstanding Away support from the Fans once again! YTBz 🐯✊️#COYF— Junior Moors (@Jnrmoors) August 11, 2017
Carney failed to add the extras, though, and Castleford increased their lead on the hour when Paul McShane burst over from dummy half, with Gale adding the two points.
Jy Hitchcox then delighted the travelling support at the AJ Bell Stadium in the 64th minute by racing clear to touch down in the left corner, a try that was awarded after confirmation from the video referee.
Gale missed the touchline conversion but he made certain of the victory five minutes from time by splitting the posts with a drop goal as Castleford went 10 points clear at the top of the Super 8s standings with five games of the season remaining.
Castleford coach Daryl Powell was delighted with the victory.
Ytbzzzz!!! Awesome to bounce bak n win in those conditions. Thank you to our fans! Look fwd to a packed out jungle next week. ✊🏾 #CAS— Ben Roberts (@ben02roberts) August 11, 2017
He said: "Once we got control of our game and started maintaining possession we were fine. We had to work so hard defensively which was crucial because of the way we started the second half.
"It was a tough team performance but Zak Hardaker did some special things. Paul McShane was superb and Jy Hitchcox has been a real bonus for us. He was really good tonight.
"We couldn't be our normal selves and we had to adapt and adjust but we finished off the game real smart. I'm delighted we got the result.
"We want to get to a Grand Final and we have to be smart how we manage things. I would imagine Wakefield (who Castleford play next) are rubbing their hands together and will want to spoil any sort of party we might want to have.
"The League Leader's Shield is a piece of history and a massive tick for us - when it gets nailed on. We are looking to maintain our standards and that's the key now."
Salford coach Ian Watson was disappointed with the result - their eighth defeat from the last nine Super League games.
He said: "I thought the effort over 80 minutes was there. We were knocking on the door but we needed to turn opportunities into tries.
"We just couldn't manage that and that's credit to Castleford. In the first half we got some rough calls - I don't know how Manu Vatuvei's try which was disallowed in the first half wasn't given.
Great effort by the boys tonight 👏🏻 fans were awesome as they have been all year! 🐯 Yeah The Boys! #Boyo's— Zak Hardaker (@zakhardaker1) August 11, 2017
"We looked a bit more dangerous and if we stick with that effort going forward we will learn. We are missing a bit of know-how and need to be ruthless in our defence.
"But we are learning every week. It's tough for us because of the losing run we are on but I know we can turn it around.
"As a club we have progressed well as a club and team but we have to learn from games like tonight."
