The home team got off to a dream start and scored in the sixth minute.
Omar Faraj, on loan from Levante, was responsible for a fine preparatory work where the ball via Dijan Vukojevic reached Rasmus Örqvist who distinctly put it there.
Degerfors was on and the aforementioned Faraj was also close to scoring, but Ricardo Friedrich made a great save in the away goal.
Degerfors up to the qualifying spot
Instead, Kalmar got the last word of the first half.
After a dribbling raid by Sebastian Nanasi, Oliver Berg was able to net the ball just before the break.
But this was Degerfors' afternoon.
In the 63rd minute of the match, Örqvist-Vukojevic was at it again, and the latter scored with his half-volley for the second game in a row.
Degerfors won 2–1 and thus moved up to the qualification spot.
