Highlights included fighting Antonio Amaya,[2] beating future world title challenger Francisco Coronado twice,[3][4] future Alexis Arguello world title challenger Diego Alcala[4] and Love Allotey,[5] losing to former world champion Alfonso Frazer[6] and challenging Ricardo Arredondo for the Mexican's World Boxing Council's world Super Featherweight (Junior Lightweight) title, losing to Arredondo by a somewhat controversial and close but unanimous fifteen round decision with scores of 145-146, 142-146 and 141-149 in favor of Arredondo, on Saturday, January 29, 1972, in the Costa Rican capital of San Jose.[7] Later on in his career, he lost to Antonio Gomez and to Bazooka Limon

Marin had 37 wins, 30 losses and 1 draw (tie), with 18 wins by knockout.
