Hammarby continues to impress in the Swedish Cup.
Last weekend it was 4-1 against AFC Eskilstuna and it followed the Stockholm team with a planned victory away against Oskarshamn on Sunday.
Already after six minutes, they got in 1-0 after an own goal.
It took until the 58th minute before Akinkunmi Amoo was able to put his own return and double the lead.
Just three minutes later, Vladimir Rodic extended to 3-0, played by newly acquired Astrit Selmani after a quick conversion.
There were no more goals and the victory means that both AIK and Hammarby now stand at six points.
Therefore, next week's derby team decides between who goes on from the group.
AIK must win to advance. For Hammarby, a draw is enough.
