The lone game on the WHL playoff trail Thursday had the Everett Silvertips in Portland.
The Tips won the game 3-2 to take a 3-1 lead in the series.
Portland took a 2-1 lead in the 3rd when Henri Jokijarju scored on the power-play at 17:53, but Garrett Pilon tied it nine seconds later with Wyatt Wyllie getting the winner for Everett at 18:48.
The Silvertips will look to finish things on home ice Friday night.
The winner of the series will meet Tri-Cities in the Western Conference final. The Americans have not lost in the playoffs having registered sweeps against both Kelowna and Victoria.
