Hammarby had to do without Madelen Janogy, suspended after the high-profile red card push last time. But the fact that Bajen was missing one of his most high-profile scorers was not noticeable.
Matilda Vinberg set the standard with an early lead goal after a deep ball from Alice Carlsson. And then it just rolled on.
Hammarby had a total of 20 finishes on goals compared to Kalmar's zero, and six different scorers on the total of eight goals.
The delicacy of the match was two-goal scorer Matilda Vinberg when she heeled the ball on Sara Kanutte Fornes, who also became the two-goal scorer in the match, to make it 3-0.
Especially difficult for Kalmar, who is already injured, was that goalkeeper Anna Koivunen had to leave with a feared knee injury in the first half. She was replaced by Fanny Jungward.
Hammarby, who are still unbeaten after six games in Damallsvenskan, now top the table three points ahead of the nearest chasing BK Häcken.
