Colin McMenamin continued his great goalscoring form to return Gretna to the summit of the First Division. The Gretna striker opened the scoring in the 39th minute and Danny Granger grabbed a second for the visitors on the stroke of half-time.
And McMenamin hit his fourth in two games in the 88th minute to wrap up a comfortable victory in Dumfries.
The three points extended Gretna's 100% record this season and put them two points clear at the top of the table.
