Established in 1880, the Metropolitans spent the first three years as an independent club before joining the American Association for the 1883 season. During this time the Metropolitans, along with their fellow National League rivals, the New York Gothams were owned by John Day. The team would win the league pennant in only their second year in the league, but were swept by the Providence Grays in a 3 game post season series, behind the Grays' ace pitcher Old Hoss Radbourn. The next three seasons found the team finishing in 7th place. The Metropolitans would drop out on October 8, 1887. The current New York Mets team is named after the old Metropolitans team, but is popularly referred to as the Mets.
