Aaron Rapoza fired four scoreless innings of one-hit relief as the Damien Monarchs rallied to a 2-1 victory over Waianae in Division II semifinal action at Les Murakami Stadium.

Damien will meet Kamehameha-Hawaii for the D-II state championship on at 10 a.m. Saturday at Moanalua.

Damien (6-10) is the two-time defending state champion in D-II under coach Skyler Tengan, winner in three of the past four state tournaments.

Trailing 1-0 entering the bottom of the fifth inning, Rydge Kohagura led off with a triple to right-center. With one out, Maximillian DeTrinis singled to left, scoring Kohagura to tie the game.

In the sixth, Francis O’Connor singled to center and advanced on a sacrifice bunt by Nainoa Begonia. After Rapoza was intentionally walked, both runners moved up on a passed ball. Tryten Vicari’s sacrifice fly to right allowed O’Connor to score the go-ahead run.

Rapoza then retired the Seariders 1-2-3 in the top of the seventh to seal Damien’s victory.

OIA champion Waianae closed the season 12-3.
