The Baltimore Mariners were an indoor football team based in Baltimore, Maryland. The team was founded when the American Indoor Football Association expelled the Baltimore Blackbirds for negotiating with another league. The AIFA maintained the lease rights to 1st Mariner Arena, so the Mariners were the league's replacement. On September 3, 2010, team owner Dwayne Wells was arrested on charges of wire fraud from an engineering firm he partially owned, allegedly using embezzled money from the firm to buy stakes in the Mariners franchise. Wells forfeited his ownership of the team, causing the Mariners to fold after the 2010 season. The Southern Indoor Football League, as successor to the eastern half of the AIFA, still holds the lease on 1st Mariner Arena.
