Alexandria Dukes / Alexandria Mariners
The Alexandria Dukes were a Class A Carolina League minor league baseball team that played in the Washington D.C. suburbs from 1978 through 1983. During the 1979 season, the team was known as the Alexandria Mariners thanks to a short-lived affiliation with the American League’s Seattle Mariners. The Dukes enjoyed their greatest success as a Pittsburgh Pirates farm team from 1981 to 1983, including a Carolina League title in 1982. The team moved away to Woodbridge, Virginia in 1984.
