First Division leaders Gretna produced a fine performance to sweep past lowly Ross County at Rayeale Park.
Gretna opened the scoring in the ninth minute when Colin McMenamin netted from the penalty spot and two minutes later David Nicholls blazed in a free kick.
County were reduced to 10 men when Alex Keddie was shown a second yellow card.
McMenamin shot home his second before a volley from Diarmuid O'Carroll caught Gretna by surprise. Alan Jenkins made it four when he rounded the keeper.
