San Clemente used a combination of defensive pressure and hot shooting to jump out to a 28-4 lead after one period, which was more than enough points already in their 64-24 victory.
Army and Navy only got into double-figure scoring during one quarter, the second, when they tallied 11. Otherwise, it was all Tritons.
For the second consecutive game, San Clemente scoring was led by Blake Birmingham, who had 25. Also in double figures were Aidan Butler with 13 and Roberton Medrano with 11. Evan Banks added eight; Dylan Hauser, 3; and Chris Kane and Daniel MIrcheff, 2 each.
In the semis, the Tritons will be facing an opponent on its home court for the second consecutive night.
