1890 Baltimore Orioles season
The Baltimore Orioles team left the American Association after the 1889 season and started playing in the minor Atlantic Association. However, when the Brooklyn Gladiators ballclub folded mid-way through the 1890 season, the Orioles returned to the AA to finish out the season.
