The 1900 Brooklyn Superbas captured their second consecutive National League championship by four and a half games. The Baltimore Orioles, which had been owned by the same group, folded after the 1899 season when such arrangements were outlawed, and a number of the Orioles' players, including star pitcher Joe McGinnity, were reassigned to the Superbas.

Joseph Jerome McGinnity was an American right-handed pitcher in Major League Baseball (MLB) in the late 19th and early 20th century. McGinnity played in MLB for ten years, pitching for the National League's (NL) Baltimore Orioles (1899) and Brooklyn Superbas (1900), before jumping to the American League (AL) to play for the Baltimore Orioles (AL) (1901–1902). He returned to the NL with the New York Giants (1902–1908). McGinnity continued to pitch in the minor leagues, eventually retiring from baseball for good at the age of 54.
