The Häcken heel chanted "SM gold, SM gold" when Rygaard punctured the match in the 82nd minute, and large parts of the IFK Gothenburg supporters had already gone home.
The effectiveness of the hedge impressed.
In the first half, they had four shots on goal and put three balls in the net.
IFK Göteborg, who only lost at home against Häcken once before, played a pretty good match but were still without a chance.
Hecken played with a golden shine throughout the match.
And the guests immediately silenced the crowd.
A really nice attack where Simon Gustafson made a heel pass to Blair Turgott just outside the penalty area.
Turgott could afford to slip up when he turned away Johan Bångsbo in the Gothenburg defence, but still managed to get a shot.
A hard shot in the right corner that Warner Hahn had no chance at.

Blair Turgott replaced the suspended Jeremejeff
Marcus Berg had a golden opportunity to equalize minutes later.
Free towards the goal, however, he took a little too long to get to the end.
Johan Hammar in Häckenförsvaret managed to break the shot attempt.
And the Hisings gang, who have been hyper-dangerous going forward all season, once showed where the cupboard would stand when they got a corner in the 16th minute.
Johan Hammar broke free in the penalty area and was able to head the ball in undisturbed to make it 2-0.
- We have our game, we can't do anything else, Hammar said at half-time, about how Häcken completely pushed forward in the beginning of the match.

Johan Hammar nods into second place
Hecken increased the score to 3-0 in the 31st minute, and thus the SM gold was basically complete.
Gothenburg opened up for Häöcken when Oscar Wendt left and Mikkel Rygaard Jensen was given free rein.
He advanced completely undisturbed in the middle and was able to slot the ball in behind a frustrated Hahn.
In the second half, which was a sleeping pill compared to the first, Blåvitt tried to come back, but Berg missed the best chance to reduce when he nodded straight into the arms of the Häcken goalkeeper.
Instead of 1-3, it was 4-0.
And it was Rygaard who struck again.
With a deliciously well-placed shot, he put the ball there in the 82nd minute.

Rygaard places the third
- Häcken showed today that they are several numbers bigger than IFK Göteborg.
Despite the surface at Gamla Ullevi, they show class by mastering that too, says SVT's expert Daniel Nannskog.
