Sheffield United moved back into the Sky Bet Championship play-off positions after two goals in three second-half minutes saw them breeze to a 3-0 victory over lowly Sunderland at Bramall Lane.
John Lundstram put the Blades on the way to a first win in seven games in the 36th minute when he slotted home a cross at the far post from Mark Duffy, who tormented the Black Cats all afternoon.
Richard Stearman doubled United's lead in the 59th minute with a fierce header into the bottom corner before George Baldock made it three with a close-range header into the roof of the net moments later.
