Corbin (3-3-1) moved back in front with 1:51 to play before halftime when Trey Monaco scored.
"They owned us in the first half," Reynolds said. "We couldn't get anything going. We looked like Keystone Kops at times."
Danville outshot Corbin 9-4 in the game.
The Admirals will host Somerset, a 5-0 winner over Oneida Baptist, in the championship game at 7:30 p.m. Saturday at Admiral Stadium.
Harrodsburg 4, Washington County 1 - Jared Holt scored twice as Harrodsburg (2-2) turned back Washington.
Manuel Garcia scored once, and the Pioneers also got an own-goal. They had 20 shots on goal and 10 saves.
Boyle County 5, Pulaski County 0 - At Somerset, Sarah Hall scored four goals and Caitlin Day had a goal and two assists to help Boyle (4-2-1) blanked Pulaski (0-4).
Hall had two goals and Day had a goal and two assists in the first half as Boyle (4-2-1) opened up a 3-0 lead.
Hall added two more goals in the second half, but coach Brian Deem said there was plenty of praise to go around.
"It's a process for us right now, but I think we're playing well," Deem said. "Marissa Hibbs did a fabulous job for us, and all of our backs did well. Our outside mids, Kelsey Arnett, Erica Adams and Emily Woolum played great. But Caitlin Day was the standout tonight, even though Sarah Hall scored four goals. Day was fabulous in the field for us today."
