Patrick Bamford nodded in a late winner to give Leeds a 1-0 win over local rivals Sheffield United at Bramall Lane.
The Premier League’s first Yorkshire Derby was dominated by defensive stubbornness and neither side looked set to find a breakthrough.
But a superb cross from Jack Harrison just three minutes from time was met by Bamford who nodded the ball beyond Aaron Ramsdale to give his side three points and their first away win since their return.
Bamford became the first Leeds player in 52 years to score in three straight top flight matches and make it two straight wins since their opening day defeat to Liverpool.
Marcelo Bielsa’s side were saved by goalkeeper Illan Meslier in the first half as he pulled off an early save of the season contender to deny John Lundstram.
Lundstram looked certain to score as he arrived to meet a cross at the back post only for the outstretched Meslier to parry his effort away.
But Leeds grew into the game and ended the first half on the ascendency with no side able to break the deadlock.
The visitors started brightly in the second half with Helder Costa, Mateusz Klich and Patrick Bamford both forcing smart stops from Ramsdale before the hour mark.
