BRECHIN City ended the season on a disappointing note, going down at Dumbarton by four goals to two.
The result means that the reds end the current campaign in third bottom spot, having been edged out of seventh place in the table by near-neighbours Forfar Athletic, who got the win they required to remain clear of the relegation play-0off spot.
Brechin came close to an early lead when Charlie King’s corner found the head of Craig Molloy but he failed to direct his header.
James Lister and Rory McKenzie both went close before the break but were denied by keeper Arnaud Gastal as the hosts held firm.
But City did take the lead eight minutes after the restart, King with a stunning volley inside the area from David McKenna’s cross.
However, Dargo struck an equaliser six minutes later when he collected Anthony Wallace’s pass before firing into the corner.
And they were ahead soon after when Dargo headed home David Gray’s cross before sealing his hat-trick with another header 18 minutes from time.
Craig Molloy pulled a goal back two minutes from time before Glen Thomson added a fourth for the Sons deep into stoppage time.
Dumbarton - Gastal, Finnie (McNiff), Kennedy, Lyden, Nugent, Gray, Nicoll, Wallace, McKell (Thomson), Dargo and Mptata (Walker).
Brechin City - Scott, Webster (McClune), Buist, Moyes, Hodge, McKenzie, Fusco, Molloy, McKenna (Crawford), Lister and King (Carcary).
