The Dynamo finished last in the league during the team's first two seasons. In the 1989–1990 season, the Dynamo won the National Division, but the squad lost to the Canton Invaders of Canton, Ohio, in the championship series. The team returned to the championship round the following season, losing to the Chicago Power this time. During the 1991–1992 season, the Dynamo, now in the National Professional Soccer League's American Division, finished last. Over the next three seasons, the team finished no higher than fifth in its division. Declining support from Dayton fans prompted the Dynamo to relocate to Cincinnati, Ohio, at the end of the 1994–1995 season. In Cincinnati, the squad became known as the Cincinnati Silverbacks.
In 2015, the Cincinnati Saints announced that they would relocate to Dayton and operate as an outdoor team renamed in honor of the old indoor team for the 2016 season.
