West Ham overcame a spirited Hull side to keep pace with Southampton at the top of the Championship table.
Jack Collison's composed finish added to Sam Baldock's close-range volley to keep the Hammers within five points of the Saints.
Both goals came in the second half to complete a sixth away victory of the season for Sam Allardyce's men.
Poor finishing and good goalkeeping from Robert Green denied City, who dominated in the opening 45 minutes.
Robert Koren and Matty Fryatt both went close in a first half which was one-way traffic towards the West Ham goal.
It took the Hammers 31 minutes to register their first effort on goal, but they were soon into their stride after the interval.
The catalyst for the turnaround was the introduction of Carlton Cole, in place of John Carew.
The switch seemed to pay almost instant dividends when Papa Bouba Diop set up Baldock to lash home from six yards out.
And, as the Tigers pushed men forward in a bid to get back into the game, Cole's neat pass split the home side's defence and Collison showed great maturity to pick his spot and double his side's advantage.
Hull did everything to get themselves back into the contest, but good defending by Julien Faubert and more top saves from Green denied them a deserved share of the spoils.
VIEWS FROM THE DRESSING ROOM
On being linked to Leicester, Hull boss Nigel Pearson told BBC Radio Humberside:
"Did we deserve to lose the two games we've played? Probably not.
"We get back to working hard for the next game because the division is still pretty tight.
"As far as I am concerned, my job is my job and I do it as best I can and I will always do that.
"So I am now not going to turn it around the other way. You will have to ask the club if they have had an approach but I don't think they have.
"My job is to do this job as well as I can and if that changes then you'll know from the club, you won't hear it from me."
