Stenhousemuir's 4-1 win at Stair Park was thoroughly merited.
The Warriors dominated proceedings and Isaac English punished Stranraer after 35 minutes with a wicked drive.
But the visitors second and third goals, either side of a Billy McDonald 30 yard screamer for Stranraer, both had a hint of offside about them.
In the 50 minute Scott Miller beat home keeper Mark McGeown with an angle drive.
The flag stayed down again when English ran onto a through ball and chipped it smartly over McGeown.
Blues boss Billy McLaren was far from happy and ran on to the pitch in protest after the goal was awarded.
It was no surprise when Paul McAneny made it four from close range 12 minutes from time.
