SEATTLE - Taylor Prosychen scored the tiebreaker in the third period, lifting the Tri-City Americans to a 3-2 win over the Seattle Thunderbirds on Tuesday.
The win gives the Americans a 2-1 lead in the WHL Western Conference semifinal series with Game 4 scheduled for Wednesday in Seattle.
Jim O'Brien's first goal of the playoffs gave the T-birds a quick lead. The goal, on the first shot on net by Seattle, was a nicely placed wrist shot over Chet Pickard at 3:36 of the period.
Tri-City tied it when Shaun Vey snapped in a rebound after a shot by Procyshen with the Americans on the power play at 4:39 of the period.
The Americans took the lead at 13:09 of the period on another power play goal, this one controversial because the referees didn't make the signal but the light was turned on.
After conferring, Adam Hughesman was credited with the goal.
O'Brien tied the game with his second goal of the game, which came after Riku Helenius made several heroic saves as the Americans fired off 18 shots in the period.
O'Brien, a first-round draft pick of the Ottawa Senators, now has two goals and six assists in the playoffs.
Helenius had 42 saves for the Thunderbirds, which were outshot 45-24 by the Americans.
The T-birds again played without captain Thomas Hickey, who suffered a concussion in Game 1.
