During the Civil War, Elorriaga fought for the Republican side under the Battalion led by Commander Luis Urkullu, which surrendered in Barakaldo to the national forces.^[6] After spending four months in the Carmelo prison in Begoña, he joined the Naval, where he briefly played for Deportivo Alavés in the 1938–39 season.^[6] After the war, he signed for Zaragoza, then in the First Division.^[6] In total, he scored five goals in 26 league matches throughout two seasons, the latter of which ended in relegation.^[1][2]
