In-form Leeds moved back into the Championship play-off places after securing a gritty 1-0 victory against Hull.
Pablo Hernandez grabbed the decisive strike just before the half-hour mark - cashing in on a goalkeeping error - as Thomas Christiansen's men registered a hugely impressive fifth victory in seven matches.
Hull's worries increased under new boss Nigel Adkins.
Their recent boost was halted and they have now won just once in their last 10 games.
The visitors enjoyed the better of the opening exchanges at a packed Elland Road. The crowd of 35,156 was Leeds' best of the season so far.
Barely a minute had passed when Kamil Grosicki saw a sweetly-struck 25-yard effort superbly saved by Leeds keeper Felix Wiedwald.
Shortly after Grosicki found space once again, only this time his shot was bravely blocked by Pontus Jansson.
The Tigers rallied again and almost went in front when Ola Aina fired an effort narrowly over the top.
It was hugely against the run of play when Leeds broke the deadlock.
Hernandez pounced on a poor clearance from Hull's Allan McGregor, latching onto a loose ball before charging forward and chipping the Tigers' 'keeper to register his fifth goal of the season.
Hull were then denied by the woodwork as Spaniard Jon Toral saw his 20-yard pile-driver strike the post.
McGregor did his best to redeem himself just before the break. He saved brilliantly from Gjanni Alioski after he had been neatly teed up by Pawel Cibicki.
After the restart Leeds were on top in the early stages, with Luke Ayling unlucky as he just failed to stretch enough to meet Alioski's free-kick.
Hull responded with Australian midfielder Jackson Irvine then inches away from connecting with Toral's inswinging corner.
Another terrific delivery from Toral was met by the onrushing Kevin Stewart, but his header was directed over the crossbar when he really ought to have done better.
Stewart went close again minutes later, this time crashing a low shot narrowly wide after meeting a neat pass from Fikayo Tomori.
Leeds were hanging on as the final 20 minutes approached, but they did break and Cibicki whipped in a dangerous cross which had to be frantically cleared by Aina.
The hosts were hunting a second in the closing stages, and Cibicki almost netted when he fired over the top from an acute angle after meeting Jansson's pass.
Sub Pierre-Michel Lasogga then forced McGregor into a fine stop.
