Donegal Celtic 0-3 Ballymena Utd
James Costello's double helped the Sky Blues to a deserved three points in the Premiership clash at Suffolk Road.
Allan Jenkins set up the striker for the opener in the first minute, with Costello turning and firing past DC keeper Robert Robinson.
Costello hit the net from a tight angle to double the lead while DC forward Paul McVeigh shot wide from six yards.
United sealed the victory three minutes after the break when Alan Davidson's half-volley found the top corner.
