A native of the Chicago suburbs, Ross Baumgarten was selected by the Chicago White Sox in the 20th round of the 1977 amateur draft. He had been a high school teammate of John Castino. He went 9-1 with a 1.82 ERA in 10 starts for the Class A Appleton Foxes of the Midwest League in 1978 before being called up to the majors that August. He was a member of the Sox rotation in 1979, going 13-8 with a 3.54 ERA and making the 1979 Topps All-Star Rookie Team. He also pitched a two-hitter on August 12th of that year against the Toronto Blue Jays.
Baumgarten suffered some hard luck in 1980, going 2-12 while posting a respectable 3.44 ERA. The highlight of his season was pitching a one-hitter on July 2nd against the California Angels. The lone hit was a single by Rod Carew in the top of the 7th inning.
Baumgarten was traded to the Pittsburgh Pirates prior to the 1982 season, and after one year, he was let go by the club. Despite the promise he showed early on, Baumgarten's big league career was over at age 27.
Since his baseball days he has been a financial advisor for a number of companies.
