Nicknamed “The Rabbi,” he played one season with the San Francisco Giants in 2008. A standout player at the University of California, Horwitz was ready to pursue as a career as a chiropractor after college. However, he decided to give baseball a shot. He won two minor-league batting titles before the Giants elevated him to the big leagues in 2008. The outfielder, though, only hit .222 with 2 homers and 4 RBIs in 21 games. He never got another shot, ending his career in the Cleveland farm system in 2010.
Brian played in the Maccabi Games when he was 15 and 16, leading his L.A.-area team to national titles in 1996 and 1997.
