PORTLAND, Ore. - For more than four months, the Portland Winterhawks were invincible on home ice.
The Edmonton Oil Kings ended the Winterhawks' 25-game home winning streak Friday and closed to within one game of winning their second Western Hockey League championship in three years.
Bittner broke a scoreless streak of nearly 132 minutes for the Winterhawks with his fourth goal of the series with 4:32 left in the first period to put Portland up 1-0.
Kulda responded with 1:33 left in the first on the Oil Kings' fourth power play of the period.
The Oil Kings took their first road lead of the series on Reinhart's goal 2:11 into the second period, then made it 3-1 on Samuelsson's fourth goal of the series at 7:39.
Dumba scored with 1:45 left in regulation to pull Portland within a goal, but could not find an equalizer down the stretch.
Edmonton finished 1 for 5 on the power play, while Portland went scoreless on four chances.
Edmonton, which beat the Winterhawks in seven games in the 2012 WHL finals, has won three straight games after dropping the first two of the series in Portland. The Winterhawks won last year's championship in six games over Edmonton.
