Zenón Díaz & Harry Hayes

Two of Rosario Central's early stars showing off some of the club's trophies.
Club Atlético Rosario Central evolved from Central Argentine Railway Athletic Club in 1904. The Liga Rosarina de Fútbol was founded in 1905, and Central won the first of their league  titles in 1908. They were Liga Rosarina champions 11 times during the  the amateur era (which ended in 1931). Rosario Central also won the following National titles: Concurso por Eliminación (1913); Copa Ibarguren (1914); Copa de Honor &  Copa Jockey Club (1916); Copa Competencia (1920). 
On the left is  Zenón Diaz , who, in Argentina's 4th international (15.08.06), became the first 'native' and also the first non-Buenos Aires player to be selected for Argentina. 
 To the right is Juan Enrique Hayes. Hayes, known as 'Harry' (his parents were English) was Rosario Central's first ever purchased player. He was 14 years old and his services cost the club a fee of A$4. In 1914 Hayes scored 51 goals for Central in a 20 match league season. Hayes represented Argentina 21 times (1910-19) and spent the entireity of  his 19 year club career at Rosario Central .
The photograph apparently dates from 1908, so among the silverware on display would be Copa Nicasio Vila  (Rosario First Division) and Copa Santiago Pinasco (championship of the second tier in Rosario). 

Zenón Díaz

As we have seen in earlier posts, Argentine football in its early years  was dominated by European in migrants or the sons of Europeans. Zenón Díaz was neither. He was of Rosario, a native south American, the first to play for the Albiceleste. 
In 1903 Diaz had been spotted by Rosario player (and later club president)  Miguel Green. Green was walking home from work (likely he was an employee of the railway company in which the club originated)  when he saw a group of young men playing some informal ball game in the street. He was so taken by Diaz's dexterity and athleticism that he persuaded him to join Rosario as a goalkeeper.
Diaz took to football. He soon became an outfield player, a solid defender.

 Zenón Díaz played for the combined Rosario XI against the Nottingham Forest Tourists in 1905. Weeks later he appeared in the Argentina team that took on Forest.

He made his full international debut in August 1906 in a 2-0 win over Uruguay at Montevideo. 
Diaz had to wait until August 1913 for his next international call up. This was followed by a further three year hiatus after which he made a further 4 appearances (as a 35 year old) in 1916.
