Bajen started strongest in terms of play - but despite that they got a real cold shower.
The Stockholm team ended up in a 0-2 disadvantage after 20 minutes of play, to then manage to gather strength and turn the event around and get to the semifinals of the Swedish Cup.
The shock start came when Norrköping's Jonathan Levi found Christoffer Nyman who managed to score the match's first goal after a goalkeeper mistake by the home team's Oliver Dovin.
Just three minutes later it was time again.
Hammarby was careless in the defense and Nyman sent in 2-0 after a new dubious intervention by Dovin.
Just before the half-time break, Bajen's pick-up began.
Astrit Selmani caught the ball in the penalty area and found ingeniously in to an inbound Nahir Besara who shaved in 1-2.
It did not take long before the equalizer came in the second half.
Five minutes in, the goal scorer Besara found the midfield anchor Darijan Bojanic's feet and further into the goal.
Just eight minutes later, the turn came to completion.
Selmani, with a performance from before, was caught in a duel with the opposing team's Jean Carlos de Brito and awarded a penalty.
The striker took care of the penalty himself - and he put in a cool 3-2.
It was also the end result.
Bajen is thus ready for the semifinals.
Djurgården and Elfsborg are already further in the tournament.
