The penalty box has been the Achilles Heel for the Janesville Jets this season.
That was the case again Friday night.
Kenai River scored four power-play goals en route to a 6-4 win over the Jets in the first game of the best-of-five NAHL playoff series at the Janesville Ice Arena.
The Brown Bears lead 1-0 after one period and pushed the lead to 5-1 after two periods thanks to four power-play goals in the period.
Max Helgeson, who had two assists for Kenai River, added a shorthanded goal in the third period.
Shane Ott scored two goals for the Jets.
Game two of the series is Saturday at 7 p.m. at the Ice Arena.
