The Spokane Chiefs' offense, quiet for the equivalent of 60 minutes stretching back Tuesday's game, woke up during the final 4:22 of the first period Thursday in Kennewick. Adam Helewka and Todd Fiddler scored to give the Chiefs a 2-1 lead over the Tri-City Americans in Game 4 of their best-of-seven WHL series. Spokane outshot the Americans 14-8 to overcome Justin Feser's early score for T-C. The Tri-City crowd booed lustily after Helewka's goal, convinced that Spokane's Blake Gal should have been called for goalie interference for being on top of T-C goalie Luke Lee-Knight shortly before the shot. Replays showed an Americans player pushing Gal into Lee-Knight.
