Debatably the first, but certainly among the first Latino players to play in the Major Leagues, Castro was a pitcher, infielder, and outfielder for Manhattan from 1895-1900, Castro played 42 games as an infielder/outfielder for the 1902 American League Champion Philadelphia Athletics. The Medellin, Columbia native played professionally for eight more years following his stint in Philadelphia, winning Southern Association Championships with the Birmingham Barons in 1906, and with the Atlanta Crackers in 1907.  He also managed two teams before retiring following the 1912 season.  He was known for his flawless fielding and timely hitting.
