Michela Cava bubbled in the summit between Luleå and Linköping

Both teams were undefeated before the meeting in Luleå and after a goalless first period, the home team struck twice in the middle period.

Emma Nordin stayed ahead and made it 1-0 after a quick attack where Cava found Noora Tulus who played on to Nordin.

Petra Nieminen then shot 2-0 in game five against three.

The Bullocks punished

In the third period, Cava struck twice.

First with 3-1 only 1.10 after Carly Bullock's reduction on penalties and then the Canadian also made 4-1 in powerplay.

Michela Cava leads the points league after four games with four goals and nine points, one point ahead of chain friend Nordin.

With Linköping's loss zero cracked, Luleå and Brynäs (three wins in three matches) are the only teams without a loss of points.
