The Louisville Bats, of the International League and briefly in Triple-A East, play their home games at Louisville Slugger Field in Louisville, KY. The hugely successful club's lease largely funds the Louisville Downtown Development Corporation.
In 2002, the Louisville RiverBats moved into "The Slug" - a new but much smaller ballpark that makes million-fan seasons unlikely - dropped "River" for just "Bats" and switched from the Brewers to the Reds.
Each year, the Bats play a Kentucky Derby Week game as the "Derby City Mint Juleps".
They play Copa de la Diversión Hispanic engagement campaign games as Murciélagos de Louisville - a literal translation of Louisville Bats (the flying mammal, not the wooden tool used to hurt baseballs).
