Roberto Alomar Velazquez was bom in the southern city of Ponce, Puerto Rico, on February 5, 1968. The son of Santos "Sandy" Alomar, Sr. and María Velázquez, Alomar grew up in a baseball family. He and his older brother Sandy Jr. were raised mostly by their mother, due to their father's Major League career. When school in Puerto Rico was out for the summer, they joined their father, who let his sons hang around the clubhouse, shag fly balls, and absorb the game especially from his New York Yankees teammates, such as Thurman Munson and Graig Nettles. Growing up, Alomar idolized both his father and José Cruz.
