After gathering a record of 21–1–1 as an amateur, Escobar debuted as a professional in 1931 defeating Luis "Kid Dominican" Pérez by knockout.

[2] Subsequently, he moved to New York and began boxing in other states, eventually capturing the Montreal Athletic Commission World Bantamweight Title.

Although at this time, boxing was illegal in Puerto Rico; remote places such as a house's backyard or rooftops were used to organize clandestine fights without attracting attention from the local police.

[3] In 1928, a Puerto Rican boxer named Ángel "Sotito" Soto moved from New York to a house near the Escobar family's residence and established a gym in his backyard.

[4] His draw was against Ramón Rodríguez of San Lorenzo and his only loss was in the hands of Pedro Montañez from Cayey, in a fight that took place in March 1930.

[4] Escobar turned professional on September 1, 1930, in a fight card organized at the Victory Garden gym in San Juan.

[4] In Puerto Rico, Escobar fought in 15 contests, before moving to Venezuela after the popularity of professional boxing declined in his home country.

But professional boxing suffered another decline in interest, which forced Escobar to work as an accommodator in baseball games three days of the week, generally on weekends.

[4] In the meanwhile, Tony Rojas, a friend of his managers Gustavo Jiménez and Arturo Gigante, convinced them to release Escobar of the contract which bound them.

After succeeding in this task, Rojas presented Escobar with a steam boat ticket to New York, which covered his food, clothes and hotel expenses.

[4] Escobar reached New York in early 1934, intending to "obtain fame and honor" for "[his] motherland", there he was received by Rojas and professional trainer Whitey Bimstein.

After this event, he stayed in Montreal expecting to fight against the winner of a matchup between Louis Salica and Bobby Quintana, which was scheduled to take place on December of that year.

[7] Upon arriving in Barceloneta, Escobar was recognized as a "predilect son" of that municipality by the city's mayor, which was followed by a week of festivities in his name.

[7] Escobar pursued a fight with Brown, but his offers were refused while the Panamanian pugilist promoted a campaign protesting the removal of his recognition as champion, demanding to be reinstated.

[6] On August 7, 1935, Escobar defeated Pete Sanstol—who once held, in 1931, the Canadian Boxing Federation and Montreal Athletic Commission (MAC) world bantamweight titles—by unanimous decision in 12 rounds.

[6] However, Escobar still wasn't considered the division's Undisputed Champion because Balthazar Sangchili had defeated Panama Al Brown and was recognized by the IBU.

Due to this, Sanstol sent a letter to the NYSAC noting that the fight was of eliminatory nature, even though it was recognized as a titular contest by the NBA and MAC.

[8] On November 13, 1935, Escobar became the first Puerto Rican to win a title fight in the first round, defeating "Indian" Quintana by knockout.

[8] On February 20, 1938, Escobar faced Jeffra in a rematch organized at the El Escambrón baseball park in Puerta de Tierra.

His remains are interred at Cementerio Municipal Viejo in Barceloneta, Puerto Rico, according to a memorial written to honor his life.

This statue's location served as a remembrance tribute during the 94th anniversary of Escobar's birth, when a flower crown was placed at its feet.

[14] During this date, an activity was presented by Puerto Rico's House of Boxing in the library of the Pabellón de la Fama del Deporte Puertorriqueño.
