Professional baseball had been played off and on in Toledo since 1883, but the Mud Hens era began in 1896 with the "Swamp Angels", who played in the Interstate League. They played in Bay View Park, which was outside the Toledo city limits and therefore not covered by the city's blue laws. The park was located near marshland inhabited by American coots, also known as "mud hens." For this reason, the local press soon dubbed the team the "Mud Hens"—a nickname that has stuck to Toledo baseball teams for all but a few years since. After only one year, though, the team moved to Armory Park.
