Pittsburgh Ironmen

The Pittsburgh Ironmen were a charter member of the Basketball Association of America (a forerunner of the National Basketball Association). The team was based in Pittsburgh, Pennsylvania and played at Duquesne Gardens.

They ended their only season in the BAA in 1946–47 with a record of 15–45, finishing in fifth and last place in the Western Division and worst overall in the league. According to Nate Silver and Reuben Fischer-Baum, applying the Elo rating system, this was, through 2015, the worst season ever by a professional basketball team in a major league.
