The game puts Magnolia in its first Class A title game in school history. The Blue Eagles won the 2006 title as a Class AA school and was reclassified among the state's smallest schools beginning in the 2012-13 school year.
Notre Dame, meanwhile, under fourth-year Coach Patrick Marozzi, was making its first appearance in the state tournament since two years before he arrived. Notre Dame lost in the Class A final in 2005.
"If you ask our kids, our expectations are to be here," Marozzi said. "With a bunch of freshmen, sophomores and juniors, their expectations are that we're not young. Coach Cisar just told me that we were the better team."
Magnolia was on the ropes, trailing 3-2 into the top of the seventh. However, starting pitcher Spencer Harlow walked two batters and Miller relieved. He left after getting two outs and hit a batter to load the bases when Hanna stroked his game-winning hit.
Josh Baker had two hits and two of Notre Dame's RBI.
Cisar almost made the ultimate mistake of not starting his ace, Kyle Elliott. Instead, Zack Wilhoit took the mound, going 21/3 innings and giving up three earned runs. Elliott relieved in the third and no-hit the Irish with three strikeouts and a walk.
"I probably started the wrong pitcher," Cisar said. "Wilhoit's been pitching real, real well, but, I'm thinking, 'Hey, if Wilhoit can beat this team today ...'"They were by far the better ballclub through the first three innings. The swung the bats, they hit the ball hard, and we didn't do much of anything. I decided, if I'm going to lose, I'm going to go with my best pitcher."
