It was Hammarby who had the initiative and the greatest scoring opportunities, but the Stockholm team failed to get the ball into the goal.
I don't think we're quite at the level, we have another level in us. But we still have chances to score, and in matches like this, it's about taking the chances you have, says Hammarby's Smilla Holmberg to Viaplay after the match.
Hammarby has, with one more match played, the same points, 49, as Häcken from Hisingen.
Häcken thus has the opportunity to reclaim second place when they face Vittsjö on Saturday.
Linköping is now eighth in the women's top division.
Next, Hammarby will face Austrian St. Pölten in the Champions League.
Earlier on Friday, Rosengård took the Swedish Championship gold after their 22nd consecutive win against Kristianstad at home.
