Career
He played in three different major leagues in his career: with the Cincinnati Reds in the National League (1911 to 1914), with the Saint Louis Terriers in the Federal League (1914 to 1915), and with the Saint Louis Browns and New York Yankees (1916 to 1918). Marsans and Rafael Almeida debuted together with the Reds on July 4, 1911. They are sometimes named the first major league players born in Cuba, which is untrue since Havana-born Chick Pedroes played in the National League in 1902.
(Cuban-born Steve Bellán played from 1871 to 1873 in the National Association of Professional Base Ball Players, whose status as a major league is disputed by baseball historians).
Marsans also played Negro league baseball in 1923 for the Cuban Stars (Riley, 514). He is buried at Colon Cemetery, Havana.
Marsans played winter baseball in the Cuban League from 1905 to 1928 and was one of ten players elected to the Cuban Baseball Hall of Fame in its 1939 inaugural class. In 1923, he served as manager of the minor league Elmira Pioneers.
In 1953, he managed the Havana Cubans.
