The first period was a real goal celebration and already after five minutes, 35-year-old Carl Söderberg scored his first goal since returning to Malmö.
Söderberg, who made almost ten years in the NHL, got the puck from Marcus Sylvegård and put 1-0.
The answer came quickly when Oskarshamn's new Canadian Cameron Brace equalized in powerplay.
It just kept popping in the goal cages, Sylvegård made it 2-1, Johan Johnsson equalized and already after 13 minutes came the match's fifth goal.
Christoffer Forsberg took advantage of the home team's carelessness and put a backhand in a numerical disadvantage.
At the end of the period, Sylvegård got into a fight with Tomas Zohorna and both went on a five minute expulsion.
The Malmö player was not gracious in the break interview that followed.
- He grabs my leg, almost like a "slew foot".
Something the judges do not see.
I think they are extremely bad.
I will probably be fined now because I said something bad to the judges in this PK-Sweden, he says to CMore.
In the second period, Carl Persson extended Malmö's lead to 4-2.
Oskarshamn played well at times, but did not get a hole on Daniel Marmenlind in the Malmö box office.
At the end of the period, another Sylvegård, namely Emil, made it 5-2 in the open box.
- I think we give away simpler goals than Malmö does, says Oskarshamn's coach Martin Filander.
Malmö has started the SHL season in the desired way as they have two straight victories.
