It was Södertälje who took the lead when Emil Alba steered in the lead goal.
The guests dominated the first period, but it was like blown away to the second.
Then it was instead Troja-Ljungby who was better in front of their home crowd and they also got the equalizer through Daniel Karlsson Thörnros.
In the closing period, Alba had a great opportunity to end the match series.
He almost got an open goal after a shot, but did not manage to get hold of the puck.
The home crowd and the Troja players were really annoyed in the final minutes of the regular playing time.
First because the referees missed that Södertälje for a short time had six outfielders on the ice and then for a missed expulsion when Carl-Johan Sjögren got a SSK club in the face.
But it was 1-1 and the match went to extra time.
Once there, just one was not enough, but only in the second extra period Gustav Willman Borvik decided for Södertälje.
Thus, the match series ended 4-2 to Södertälje, which may remain in the country's second highest series.
