The Miners earned their spot after sweeping Cedar High School last week in the best-of-three series to qualify for the playoffs.
The Friday and Saturday contests were the final games Park City will play at its current baseball stadium.
Last month, the city’s planning commission approved a permit for a new sports complex along with other additions to Dozier Field. The district hopes to install new turf fields for baseball and softball later this year.
Parents and students say the current grass field has made baseball and softball play difficult in the spring due to lingering snow.
Park City’s game starts at 7 p.m. in St. George. If they win, the Miners will advance to a semifinals matchup with the winner of Monday's Desert Hills and Crimson Cliffs game.
