Vianney (21-7) meets Rockhurst in the final Saturday at 8 p.m.
Coach Steve Bieser led Vianney to the title game in his first year.
"I knew coming in that we had a chance because any time you get to the high school playoffs and you have one dominate guy like we do, everyone knows that we have a great chance to win that day," Bieser said.
Golden Griffins pitcher senior Nick Schmidt (9-3) walked nine and also struck out nine. Sophomore Jim Klocke relieved him in the top of the seventh.
"We all came here focused and ready to play," Klocke said. "We didn't really hit the ball at first because the pitcher kind of caught us off-guard, so we came in threw strikes and put good defense behind them."
