Two goals from Gary Harris helped Fraserburgh take the points at Lossiemouth in a keenly contested encounter on Saturday.
Fraserburgh went ahead in the 14th minute through Harris but Lossie levelled 12 minutes later, Willie Mathers forcing the ball over the line from close-range.
The Broch scored the winner from the penalty spot in the 76th minute, Harris converting after he had been brought down in the box by right back Connor Macaulay.
Fraserburgh assistant-manager James Duthie said: “Gary was very good again and overall we more than deserved to win the game as apart from a short spell we pretty much controlled it.
“Grant Park is an awkward place to go, you need to dig out the result and that’s we did to keep us on a decent run of form.
“Scott Henry had a good debut too. We played him in a holding midfield role as, with Ryan Christie missing, we put him there to give us a bit of height.
“Considering he has not played for a long time he did extremely well and l’m sure he will do well for is from now until the end of the season.”
Coasters manager Charlie Charlesworth said: “We did make a few mistakes, including conceding a soft penalty but there were times when we were really positive against a team who look like finishing in the top six.”
