Alfonso Márquez played for the high school team of Ateneo de Zamboanga where he was mentored by a Jesuit priest. He was later scouted by coach Eddie Gullas who convinced him to suit up for the Green Lancers collegiate team of the University of Visayas (UV). He came into wider public attention due to UV's upset 74-63 win against the Ateneo de Manila in an intercollegiate tournament in Manila in 1957.

He later played for Meralco and Mariwasa during the 1970s in the Manila Industrial and Commercial Athletic Association.
Márquez was a former member of Philippine national team. His performance playing with the University of Visayas gained the attention of head coach Baby Dalupan helping Márquez secure a place in the Philippines roster for the 1959 FIBA World Championship in Chile.[2]
Márquez has also suited up for the Philippines at the Olympic Games participating in 1960 edition in Rome and the 1968 edition in Mexico City. In the 1960 Summer Olympics, the Philippines placed 11th and in 1968, the national squad placed 13th.[2] Márquez played a significant role in the Philippines' 63-60 win against South Korea in the play off for 13th place.
