Oxford Utd 1-2 Morecambe
Stuart Drummond's winner earned Morecambe a surprise victory at play-off hopefuls Oxford.
The visitors struck in just the third minute when Craig Curran headed in Danny Carlton's cross from the right.
But the U's levelled almost immediately when Scott Rendell slotted home after Barry Roche parried Asa Hall's effort.
Both teams then had chances to score but the Shrimps grabbed the win when Drummond nodded in Lewis Alessandra's near-post corner.
