Rovers managed to limit the previously unbeaten Wolves to just two tries and kept them scoreless for the remaining 49 minutes.
It was the Red and Whites second win of the season and was the perfect antidote to put the Salford blues behind them.
Sandercock said to the Hull Daily Mail: “If we want to win games and be competitive, then we need to do that consistently. Keeping Warrington to two tries gives belief to the boys in the systems and structures that we have in place. We work hard on them.
“Good sides perform like this every week like Warrington and Leeds. That’s why Warrington are the benchmark. It’s heartening and showed the boys had the heart and desire to defend. Full credit goes to the players.”
However the head coach refused to get carried away with the superb victory and said: “We’re not getting carried away by this result. Warrington had quite a few players out and that stifled their attack.
“The boys played well after getting an even share of play and penalties. We did some little things well and I was impressed with the whole display in attack and defence.
It was an debut win for marquee signing Travis Burns and Sandercock was pleased with his contribution: “Travis did well given it was his first run since July. He brought positivity, communication, competitiveness and determination, which is what I wanted.”
