Doncaster Rovers 0-3 Leeds United
Leeds earned a rare away win to maintain their top-six challenge with a resounding victory at struggling Doncaster.
Leeds were the better side in the first half and went ahead when Matt Smith headed in Alex Mowatt's free-kick.
Rovers were unlucky not to equalise when Theo Robinson had a goal controversially ruled out for offside.
But Leeds cashed in when Ross McCormack scored against the run of play before he crossed for a Rodolph Austin strike.
The scoreline flattered Brian McDermott's Leeds side after Doncaster dominated the second half, with their disallowed goal a particular frustration.
After losing six of the last seven games away from home in all competitions, it was a vital win for Leeds's promotion ambitions.
Leeds's top scorer McCormack headed over the bar in the 17th minute after Smith had nodded the ball across the face of goal following a corner.
Smith then converted from a floated ball from teenager Mowatt, who was playing against his home-town club.
Rovers responded when Richie Wellens had a goalbound shot deflected and they had a great chance to equalise in the 44th minute after Robinson had brilliantly controlled a through ball from Wellens but he made a complete hash of the shot and fired high over the bar.
After Smith headed over the top at the other end, Doncaster were on the front foot in the second half, with Wellens twice going close before Robinson's effort was disallowed.
The hosts were stunned when McCormack scored in opportunist style in virtually their first threatening moment of the second half before Austin added insult to injury from McCormack's right-wing cross in the 87th minute.
Doncaster manager Paul Dickov on Theo Robinson's disallowed goal:
"I haven't had an opportunity to speak to the referee yet but intend seeking him out for an explanation.
"I've had the benefit of replaying the incident about 20 times on the video and Theo is clearly a yard on side.
"But the late flag has baffled me as much as anything else. It looked as if the linesman thought he was on side but changed his mind when Theo scored.
"It's a massive decision because we were all over them at that stage and had we got a goal it could have changed the course of the game.
Leeds boss Brian McDermott:
"It was a tough game - there's no getting away from that.
"I thought we were good value for the lead in the first half but we just couldn't get out of our half after the interval.
"Doncaster came out in the second half and played really well. We had to change our system to combat that and we did better when Michael Brown came on midway through the second half."
