Bottom club Lisburn Distillery slumped into deeper relegation trouble when they lost away to fellow strugglers Donegal Celtic.
Stephen O'Neill ran on to a Mark Miskimmin flick to shoot DC into the lead in the 13th minute.
Dom Melly went close on two occasions for Distillery but Sean Cleary made it 2-0 on 65 minutes with a curling shot which went in off both posts.
Johnny Harkness shot in a goal for Distillery but it was not enough.
The Whites are now eight points adrift at the bottom - a huge margin for a team which has won just three Premiership matches all season.
