Originally signed by the Cardinals in 1962, Cosman made his pro debut the following summer and reached the majors on the final day of the 1966 season. He made hig big league debut on October 2nd of that year, starting against the Cubs. He pitched a two-hit shutout and earned the win; the two hits were a second-inning single by Ron Santo and a ninth-inning single by Glenn Beckert.
Cosman went 1-0 with a 3.16 ERA in 10 outings for St. Louis in 1967 but spent most of that year in the minors. He did not return to the majors in 1968, and after that season, he was dealt to the New York Mets for Jerry Buchek. After one year in the Mets system, he was selected by the Cubs in the 1969 Rule V Draft. He made one appearance for Chicago in 1970, a relief outing against the Atlanta Braves on April 30th. Pitching two thirds of an inning, he gave up three earned runs, including a solo home run to Hank Aaron. He spent 1971, his final pro season, with the Indianapolis Indians.
Following his baseball days, Cosman worked in the waste business. He began as a driver in 1972 and retired as President of Republic Services. He died in 2013 after a long battle with Alzheimer's Disease.
