Carlos Torres was born in Santa Cruz, California after his father, Jose, emigrated from Zacatecas, Mexico. As a child, Torres moved from house to house in Santa Cruz County's "south county" agricultural region where his father looked for work to support his five children. Before focusing on baseball, Torres lettered in four sports at Aptos High School, graduating in 2000. His father encouraged his playing sports in order to keep him active and out of trouble.
