A native of Glencoe, Ill., and a graduate of New Trier High School, Baumgarten played most of his five-year career on the Chicago White Sox. He finished fourth in the American League Rookie of the Year voting in 1979 and, in 1980, he pitched a one-hitter against the California Angels, with Rod Carew managing the lone single in the top of the seventh. In his first Major League season in 1978, he was teammates with Steve Stone and Ron Blomberg, creating a trio of Jews on the same White Sox team. The following year he was in the dugout for the famed “Disco Demolition Night” at Comiskey Park. Baumgarten grew up rooting for the Cubs, and he modeled himself after his favorite player, Ken Holtzman, a fellow left-handed Jew. Baumgarten became a successful financial advisor after his playing career ended.
