Oxford Utd 1-0 Barnet
Michael Raynes' last-gasp goal earned Oxford victory over Barnet and moved Chris Wilder's side to within five points of the League Two play-offs.
The U's started well with James Constable missing three early chances.
The Bees had their own chances and Ross Jenkins' strike from Luke Gambin's cross forced a good save from keeper Luke McCormick.
But in injury time Tom Craddock headed Scott Davies' free-kick into the path of Raynes to nod in from close range.
