[1] Born in Ensenada in 1910, Masantonio started his career in Villa Albino Sportivo,[1] that was affiliated to La Plata football league, where he debuted in the fourth division in 1926.

Three years later, Masantonio moved to Club Platense of the same league, where he started to show his scoring skills.

[4] Masantonio signed his first contract for Huracán, starting his career at the very dawn of the professional era of Argentine football in 1931.

I took the ball in the center of the field, dribbled the left half, then the centrehalf, and even the two backs, shooting so strong that not only the goalkeeper could not see the trajectory of the ball but many people only heard a huge strike on one of the goal posts, and nothing else.

In 1941, Masantonio was seconded by prominent players such as Norberto Méndez, Llamil Simes, and Delfín Unzué.

Since then, Masantonio has received several tributes, including a monument (inaugurated in March 1996 in front of the club headquarters on Avenida Caseros)[3] and a street with his name in Parque Patricios.

Masantonio was the inspiration for an Argentine tango titled El Mortero del Globito, written by Miguel Padula (music) and Francisco García Jiménez.
