With the score tied, 2-2, senior Trevor Schrecengost belted a two-out double that scored Jared Beach and Austin Berger in the eighth inning.

The third-seeded Tigers had a chance to take the lead in the sixth, but failed to score with bases loaded and no outs.
"It was a key ingredient to the rest of the game," Canon-Mac head coach Frank Zebrasky said.
"It was a well-played high school baseball game. We had an outstanding pitching performance.
Beach led the Big Macs, going 2 for 2 including a tying home run in the fourth, a double, a sacrifice fly, a walk and two RBIs.
