Highlights included fighting Antonio Amaya, beating future world title challenger Francisco Coronado twice, future Alexis Arguello world title challenger Diego Alcala and Love Allotey, losing to former world champion Alfonso Frazer 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. Later on in his career, he lost to Antonio Gomez and to Bazooka Limon
