Anna Anvegård struck in the 74th minute after a post from Jessica Samuelsson, who was left with a message after his injuries.
The goal meant 1-0 in the summit against Gothenburg on away and became the deciding match.
- Fantastic good finish on the move. Anna Anvegård is outstanding in Sweden at the end with a touch. That is quality, says SVT's expert commentator Markus Johannesson.
It was Anna Anvegård's ninth goal for the season. She arrived at the club last summer and has really made an impression.
The match ended 2-0 after 16-year-old midfielder Hanna Bennison bounced another post from Jessica Samuelsson in the 77th minute.
- The gold battle is not settled, Vittsjö still has weathering. But of course, now they have pole position, says Johannesson.
Rosengård leads by 38 points, four before the second Vittsjö and now eight before the four Gothenburg. The last scouts won the SM gold was 2015.
