From Ohio History Central
The Cincinnati Rivermen was a men's professional softball team from Cincinnati, Ohio. The squad was a founding member of the North American Softball League (NASL). The NASL existed for only the 1980 season, before joining with the American Professional Slow Pitch League (APSPL) to create the United Professional Softball League. In the NASL, the Cincinnati Rivermen won twenty-two and lost thirty-six games, finishing third in the league's Central Division. With the unification of the NASL and APSPL at the end of the 1980 season, the Cincinnati Rivermen ceased to exist.
