Before today's match, Närkeklubben was in the Allsvenskan's penultimate place and to have a chance to stay in Sweden's highest division, three points against Hammarby is a must.
It started hard when Hammarby initially accelerated towards Örebro's goal and got a dream situation immediately when Gustav Ludwigson was given the opportunity to finish towards an open goal - and shot high over.
But the guests it was the guests who would set the first goal and it came via a real defensive miss.
The green and white hill Björn Paulsen tried to clear a post in his own penalty area but got a real miss that made the ball look behind Oliver Dovin in goal.
Eight minutes into the second half, Bajen's answer came.
Simon Sandberg rushed into the penalty area and sent in the equalizer.
Örebro, however, showed great will and refused to give up.
In the 64th minute, the team also received a dividend when Hussein Ali came around the edge, recorded the ball to Nahir Besara who could put in 2-1.
The answer?
A lightning bolt.
Sandberg's sensitive right foot found Akinkunmi Amoo who with his forehead beautifully controlled the ball in goal.
2-2.
The lead then came in the 85th minute of the match when Ludwigson got revenge and pushed in 3-2.
Hammarby will face Degerfors in the next round.
Örebro is visited by Kalmar.
