Hull coach Peter Gentle praised his side for adapting to his changes at half-time as they came from behind to win the 220th Hull derby 38-20.
Hull were trailing 8-6 at the break and Gentle was unhappy with the way his side had performed for the first 40 minutes.
However, three tries in seven second-half minutes proved crucial as Challenge Cup finalists Hull leapfrogged bitter rivals Hull KR in the Super League table.
A penalty try for Kirk Yeaman and further touchdowns from Jamie Shaul and Joe Arundel helped the visitors turn the match around and emerge triumphant in the derby at MS3 Craven Park.
It was Hull's third successive win and a third straight defeat for the Robins and with the Challenge Cup final creeping up fast, Gentle was delighted his side came out focused for the second half.
"We had a chat and changed things at half-time," Gentle said.
"To the players' credit they adapted to it very well both in attack and in defence.
"As a coach, you are never happy to be behind.
"We squandered good possession when we got into good territory which was disappointing."
Gentle revealed the players had been motivated by a special message given to them during the week and while he would not elaborate, he said it served its purpose well.
"We got a special message during the week," Gentle said.
"I don't think the person would want me to reveal who he was.
"It was a very good message and it was well received and it certainly worked as it was a reality check for players.
"I'm pleased with the win because it was a good result for the club.
"Our under-16s won on Thursday night and the under-20s won before our game.
"It's a great effort from all the players especially with the distraction. It's a wonderful position to be in."
Rovers coach Craig Sandercock was pleased with his side's efforts despite the scoreline and losing one of his players prior to kick-off when second-rower Rhys Lovegrove withdrew.
His place went to George Griffin, who had missed Rovers' last 10 matches.
"I was really happy we competed hard and we had no right to win to be in that game at all," Sandercock said.
"To come up short like we did was disappointing.
"Rhys had a rib problem and wasn't able to play and I've no idea how long he might be out for.
"A few poor individual errors in the second half cost us big time.
"Other than that, it was nip and tuck for long periods.
"The penalty try was 50/50.
"I was happy with the way everyone of my players played
"Of course we missed the eight players that didn't play but we were in a position where we could have won that game against the odds."
