Tyrone Barnett has returned from suspension to score only his third goal in 41 games to put Oxford United ahead against Tranmere Rovers at the break.
A fairly even contest has seen few chances, as both sides look to climb out of the relegation zone.
The visitors dominated in possession but failed to turn any of it into clear-cut chances.
Barnett broke the deadlock on the half-hour mark as a neat bit of interchange with Danny Hylton put the Barnett through, where he dispatched his shot into the bottom left corner.
