The Halland side now need five points to secure a place in the Allsvenskan.
And it was a former HBK player who did the damage. Sead Haksabanovic came through the club’s ranks and curled MFF’s second goal into the far corner early in the first half.
In the second half, Daniel Gudjohnsen made it 3-0 for MFF.
Degerfors are also struggling near the bottom of the table. They suffered their third straight defeat at home to Västerås. Västerås’ Frederic Nsabiyumva opened the scoring before Axel Taonsa and Marcus Baggesen added goals to make it 3-0.
Degerfors are in a relegation play-off place, two points behind Kalmar, who are above the relegation zone.
Four rounds remain in the Swedish league.
