Oliver Bjorkstrand received the best birthday present he could hope for Thursday night.

On the night he turned 19, Bjorkstrand had a goal and three assists as the Portland Winterhawks wrapped up a second-round Western Hockey League playoff series in Game 5 with a 5-1 win over the Victoria Royals in front of 8,083 at the Moda Center.

“It’s always feels good to score on your birthday,” Bjorkstrand said.

He didn’t plan on doing too much afterward to celebrate, though.

“I don’t know what’s going to happen, but I’m pretty tired,” he said.

Portland, which won the series 4-1, has won 11 consecutive series against Western Conference opponents. The Winterhawks will compete for their fourth straight conference championship against the Kelowna Rockets, the only team in the WHL with a better regular-season record than Portland.

Thursday’s game was marred by two melees, one at the end of the second period that resulted in three ejections, and another in the third period after Victoria’s Brandon Magee cross-checked Portland’s Nicolas Petan in the back of the head.

Petan, the team’s leading regular-season scorer and offensive catalyst, was OK enough to participate in the ensuing fracas, but had to be helped off the ice following a fight with the Royals’ Ryan Gagnon.

Hawks coach Mike Johnston said afterward that it could take three or four days to evaluate Petan’s condition, but that he was coherent and talking to teammates in the locker room.

Johnston also wasn’t pleased with how the game got out of hand at times.

“You like to see the intensity of a playoff game, but you don’t like it when guys try to hurt people,” Johnston said. “I thought we did a pretty good job of controlling our emotions.”

After trading scoring chances with the Royals over the first 10 minutes Thursday, the Hawks took advantage of a power-play opportunity, as Taylor Leier banged in a rebound of a shot by Bjorkstrand to make it 1-0 with 6:14 left in the period.

Portland doubled its advantage on a goal with 34 seconds left in the first when Adam De Champlain picked up a loose puck behind the Victoria net and banked it off the back of Royals goalie Patrik Polivka’s leg and into the net.

Bjorkstrand scored 10:31 into the second, firing a loose puck into the net as Polivka was distracted by a glove that had fallen off of Leier's hand.

The Royals rebounded with a Steven Hodges power play goal to pull within 3-1 late in the second period, but the Hawks put the game away with two third-period goals by Chase De Leo.
