Nava's first time on a baseball field was when he threw out the first pitch at an Oakland Athletics' game after his grandmother entered him into a random drawing.
In his spare time, Nava enjoys playing the guitar. He plays in a band at his church back home with his brother, who is the drummer, his hometown of Los Altos, California.
