Adrián González was born in San Diego, California to David and Alba González, both Mexican natives. González is the youngest of three boys; his brothers are David Jr. and Edgar, a former big leaguer. After his birth, his parents moved the family to Tijuana, where his father owned an air-conditioner business. The three boys grew up playing baseball in Mexico, where their father had been a member of the Mexican national baseball team. In 1990 the family returned to the United States, settling in Bonita, California.
