Who are Mike Yastrzemski’s Parents?
Mike Yastrzemski spent his formative years in Andover, Massachusetts, where he was raised by his parents, Carl Jr. (known as Mike) and Anne-Marie. Growing up in a baseball family, Yastrzemski was influenced by his father, who had played college baseball for the Florida State Seminoles and pursued a career in the minor leagues from 1984 to 1988.
