Houser, the only South Sound player in the series, entered the game in relief in the seventh inning when Team Rainier trailed, 6-4, but Rainier scored three unanswered runs in the eighth for the comeback victory.
Team Rainier will face Team Adams for the championship at 3:15 p.m. today at County Stadium. Team Adams defeated Team Baker, 10-1, in the first game.
The All-State series features some of the state’s top senior baseball players. Houser was a first-team All-4A Narrows League pitcher this past spring, leading the Bears to the 4A Narrows regular-season crown with a 3-0 record.
