It was goalless for quite some time, but in the middle of the second period, the American Alexis Mauermann, who made no mistake, was freed.
Djurgården made it 2-0 just five minutes later.
Julia Östlund broke a pass and played to star Fanny Rask who shot the puck in.
On several occasions it was noticed that it was a derby as emotions ran high and there were fights on the ice.
Just three minutes into the final period, Josefine Holmgren was bent down when Amanda Andersson tackled her in the sideline in an ugly way.
Holmgren was lying down and then her teammate Linnea Natt Och Dag Andersson cross-checked so that she fell to the ice.
Andersson and Natt Och Dag each got two minutes.
There were still no more goals and Djurgården won the season's first derby.
