Kelso Thirds notched up their fourth successive victory with a comfortable away win on Saturday.
In a frenetic start, Grange scored in the first minute, only for Kelso to equalise 60 seconds later through a neat strike from Lucy Murray.
Aimee Martin then scored for the visitors to make it 2-1 after only five minutes.
The game settled down, but Kelso went into half-time 3-1 up following a second goal from Martin midway through the half. It was more of the same after the restart with Kelso pushing.
A goal from Katie Scott and a further two from Martin sealed the win.
