Amos Wilson Rusie, nicknamed "the Hoosier Thunderbolt", was an American right-handed pitcher in Major League Baseball during the late 19th century. He had a 10-season career in the National League (NL), which consisted of one season with the Indianapolis Hoosiers in 1889, eight with the New York Giants from 1890 to 1898, and one with the Cincinnati Reds in 1901.

The St. Louis Maroons were a professional baseball club based in St. Louis, Missouri, from 1884–1886. The club, established by Henry Lucas, were the one near-major league quality entry in the Union Association, a league that lasted only one season, due in large part to the dominance of the Maroons. When the UA folded after playing just one season, the Maroons joined the National League. In 1887 the Maroons relocated to Indianapolis and became the Indianapolis Hoosiers, where they played three more seasons before folding.
