The Baltimore Orioles are a professional baseball team based in Baltimore, Maryland in the United States. They are a member of the Eastern Division of Major League Baseball's American League. One of the American League's eight charter franchises in 1901, it spent its first year as a major league club in Milwaukee, Wisconsin, as the Milwaukee Brewers before moving to St. Louis to become the St. Louis Browns. After 52 mostly hapless years in St. Louis, the Browns moved to Baltimore in 1954 and adopted the Orioles name in honor of the official state bird of Maryland. The Orioles name had been used by previous major league baseball clubs in Baltimore, including the American League Baltimore Orioles franchise from 1901–1902 that became the New York Yankees and the National League Baltimore Orioles which won National League championships under Hall-of-Fame manager John McGraw, before McGraw took the black and orange team colors to the New York Giants baseball team, which became the San Francisco Giants after the 1957 season. Nicknames for the team include the O's and the Birds. The Orioles have been best known for their successful stadium, the trend-setting Oriole Park at Camden Yards, opened in 1992 near the birthplace of Babe Ruth. read more
