Nathan Holland and Matty Taylor both scored twice as Oxford got their Sky Bet League One promotion bid back on track with a 5-0 victory over AFC Wimbledon.
On-loan West Ham winger Holland and striker Taylor scored in quick succession in the first half to set up what was only Oxford's second league win since December.
It moved the U's to within five points of the play-off places.
Taylor was twice denied by goalkeeper Joe Day before he turned in James Henry's right-wing cross after 32 minutes.
Two minutes later, after a forceful run by Mark Sykes, the impressive Holland made it two with a 20-yard drive.
Henry chipped over the keeper five minutes into the second half after Marcus Browne played him through.
Holland added his second of the night with a low finish after 55 minutes, and Taylor claimed his 13th of the season with a volley in stoppage time.
Browne also smashed a 20-yard drive against the bar.
Dons' best early chance came when Simon Eastwood saved Joe Pigott's effort with his legs.
