Djurgården had no dazzling evening at home at Hovet in the Hockeyallsvenskan playoffs.
In the middle of the third period, with the score 1-1, Mora instead got the chance with numerical superiority.
The visitors' Johan Persson got an open goal, but missed, and instead Djurgården counter-attacked.
It ended with David Blomgren, six goals in the regular season, being able to shoot 2-1 for the home team.
I find a space in the middle and we get a two-on-one with "Kryckan" (Marcus Krüger), I thought first to pass but then I thought I'd take the shot. Nice to see it go in, says Blomgren to TV4 Play.
Mora had a rib shot through Ludvig Levinsson in the final minute before Max Krogdahl could make it 3-1 into an empty net.
Djurgården, who won the first match in overtime, won the shot statistics with 44-20 and had seven numerical superiorities without getting a reward.
Instead, the winning goal came in numerical inferiority.
It was a hot match in Karlskoga with 55 penalty minutes and a match penalty on home team's Leevi Viitala for a left hook on Lukas Vesterlund.
Oskarshamn, relegated from SHL a year ago, caught up from 0-2 to 2-2 after Michael Joyaux equalized with the goalkeeper pulled 1.32 before the end of the third period.
Then the visitors' Sören Dietz Larsen decided the match after 4.17 of overtime.
Thus, it stands 1-1 in matches ahead of the next two matches in Oskarshamn.
