"My grandfather was a longtime Chicago railroad worker who doubled as a terrific semi-professional ballplayer," Mike Rizzo said in a statement issued by the club on Wednesday. "A lifelong fan and student of baseball, it was his passion for the game that sparked careers in baseball for my father and myself."
Funeral services are pending. The Rizzo family requested that contributions be made in Vito's memory to the Chicagoland chapter of Autism Speaks.
