Oli McBurnie scored for the third successive game since returning from injury to help Hull secure a 1-0 victory over 10-man West Brom at the MKM Stadium.
The striker, sidelined for nearly two months due to a calf problem, struck the only goal from the penalty spot seven minutes into first-half stoppage time as the Tigers moved into fourth place in the Championship after a third win on the trot.
West Brom had Alfie Gilchrist sent off with 15 minutes remaining as they suffered a third straight defeat.
After McBurnie glanced a header wide, West Brom missed a glorious chance to take the lead in the 12th minute when Isaac Price lifted his effort over the bar from just a few yards out.
As the first half drew to a close, the home side were awarded a penalty after Nat Phillips was penalised for handball following a corner.
McBurnie made no mistake from the spot register his 10th goal 13 games this term.
Chances were few and far between in the second half but the Baggies' hopes of getting back into the game were not helped by going down to 10 men in the 75th minute.
Gilchrist was shown the red card by referee Ruebyn Ricardo for a foul on Liam Millar as Ryan Mason's side slumped to an eighth consecutive away loss.
Hull's Sergej Jakirovic:
"It was very harsh. I was a little bit surprised because I was thinking it was a yellow card. But he (referee Ruebyn Ricardo) pulled out a red.
"It was typical [of the Championship] because there were a thousand balls in the air and two thousand challenges.
"We struggled for the second ball, especially in the first half. We started well but lost our balance and West Brom were better.
"They had two great situations to score a goal and then gave us a penalty. We controlled the second half much better and had a few good chances.
"We also kept a clean sheet which is very important and got three big points. The red card also helped a lot, for sure."
West Brom's Ryan Mason:
"It is frustrating and there are so many emotions.
"The worst thing we should have come away with was a 0-0 draw. But we haven't been able to do that and away from home, it is killing us.
"I thought it was a tough game for the referee. However, I can't make excuses for us and our lack of discipline. The reality is, that's what's cost us. It was a tight game and the pitch wasn't great.
"We managed it well in the first half and we should have come in at half-time winning. But we came in losing by gifting the opposition a goal.
"It's difficult to accept and to understand why. We've spoken about mistakes, individual errors and gifts to the opposition.
"For how well we played in that first half, to come in 1-0 down in the way we did and the way the penalty was awarded was hard to understand. It's a lack of discipline and it's not good enough.
"There's a lot of pain at the moment. It's about understanding and taking responsibility. We have to own it and change it. That's the only way we move forward."
